EA: 05C3053

By submitting your resume or personal data, you consent to BGC Group Pte Ltd collecting, using, and disclosing your personal data to our clients and partners for the purpose of evaluating your suitability for job opportunities and related recruitment services. You acknowledge that you have read, understood, and agree to our Privacy Policy for Job Applicants, available at https://bgc-group.com/notice-for-job-applicants.

You can take an Interface Design Document, build the OIC integration end-to-end, handle the error cases the document did not cover, deploy it across environments, and hand over technical documentation that the support team can use a year later. That is the standard we build to.

ABOUT ROLLING ARRAYS

Rolling Arrays is a private equity-backed, award-winning HR Tech consulting firm — Asia Pacific's premium partner for enterprise HR digital transformation. Headquartered in Singapore and with offices across India, Malaysia, Australia, and Hong Kong, we have delivered more than 200 HR Transformation projects since our founding in 2009, and were recognised as one of Singapore's Top 100 fastest-growing companies in 2025. We specialise in SAP SuccessFactors, Oracle HCM, and Workday across the full delivery spectrum: HR process design and consulting (ALIGN), technology implementation (AUTOMATE), change management and adoption (ADOPT), and managed support services (AMS).

POSITION SUMMARY

RAC is hiring an Interface Developer to build Oracle HCM integrations using Oracle Integration Cloud (OIC). You will develop, test, and deploy integration flows between Oracle HCM Cloud and third-party systems, working from functional Interface Design Documents and translating them into production-grade OIC implementations.

WHAT YOU WILL DO

• Build Oracle Integration Cloud flows from functional Interface Design Documents — implementing trigger, adapter connections, orchestration logic, data transformation, and error handling without requiring functional re-explanation of the business requirement
• Configure OIC adapters across the full HCM integration surface — Oracle HCM Cloud adapter for REST API calls, HDL-based operations, and Atom Feed subscriptions; REST and SOAP adapters for third-party systems; FTP adapter for SFTP file transfer; and database adapter for ATP persistence patterns
• Build XSLT data transformations — field mapping, conditional logic, array iteration for multi-record payloads, data type conversions, and null value handling
• Configure fault handling — scope-level fault handlers, global error handlers, retry policies, and alert notifications for failures that require human intervention
• Deploy integrations across environments — configuring environment-specific connection parameters, promoting via OIC Projects, deploying to Test/UAT/Prod, and validating post-deployment in each environment
• Perform unit testing and contribute to SIT — building test scenarios for happy path, error conditions, and edge cases, documenting results, and resolving defects to sign-off

WHY ROLLING ARRAYS

Every integration RAC builds goes to a live client environment with a real go-live dependency. You will develop OIC depth across the full Oracle HCM module integration surface in APAC legislative contexts, with a clear pathway to Senior Interface Developer and Integration Architecture roles.

OUR CULTURE CODE

Six values define how we operate every day at Rolling Arrays:

• Thinking Smart — spot patterns, chase smarter solutions, and illuminate the path to greater productivity
• Never Stop Learning — refine and elevate skills constantly; explore the world with a curiosity lens
• Being Nice to Everyone — treat everyone with genuine warmth and respect, regardless of seniority
• Be Super Patient with Customers — exercise patience and proactivity in every client interaction
• Help Your Teammates — share the load, lighten the stress, nurture a truly collaborative team
• Acknowledge Your Mistakes — embrace mistakes as steppingstones; grow from each one

WHAT WE'RE LOOKING FOR

• 2–3 years of Oracle Integration Cloud (OIC) development experience on live implementation or AMS projects
• Hands-on experience building REST and SOAP integration flows in OIC — not training sandbox experience
• Practical XSLT mapping experience — can build multi-element transformations with conditional logic independently
• Experience configuring OIC fault handling and understanding the error hospital for reprocessing failed instances
• Ability to deploy integrations across environments and validate post-deployment without functional team support

PREFERRED QUALIFICATIONS

• Oracle Cloud Platform Application Integration 2025 Professional — the OIC certification; the primary target credential for an Interface Developer; at Consultant level this should be actively in progress or completed
• Oracle Fusion Cloud Applications HCM Process Essentials certified — the foundational HCM credential; understanding the HCM data model makes integration development significantly more effective
• Oracle ATP (Autonomous Transaction Processing) or ADW hands-on experience for integration persistence and parking lot patterns
• Java or Python scripting for payload pre-processing and transformation logic that OIC cannot handle natively

BUSINESS & CONSULTING SKILLS

• Technical documentation discipline — produces handover documentation that the support team can use 12 months after go-live without calling the SI
• Build-from-spec discipline — implements from the IDD without re-engaging the functional team for clarification; questions the spec before building, not during
• Deployment rigour — validates post-deployment in every environment before declaring a build complete
• Cross-functional collaboration — works alongside functional designers and client IT teams without creating communication gaps
• Fault handling ownership — does not declare an integration complete until error scenarios are handled, not just the happy path
• Learning agility — adapts to new adapter types, system APIs, and integration patterns across engagements without needing extended ramp-up

CAREER PROGRESSION

Consultant → Senior Consultant → Lead Consultant → Solution Architect → Practice Lead

You know that the integration architecture decisions made in week two of a project determine whether the support team can maintain the system for three years without calling the SI. If you build to that standard — reusable connections, governed error handling, documented deployment pipelines, clean technical handover — this is your programme.

ABOUT ROLLING ARRAYS

Rolling Arrays is a private equity-backed, award-winning HR Tech consulting firm — Asia Pacific's premium partner for enterprise HR digital transformation. Headquartered in Singapore and with offices across India, Malaysia, Australia, and Hong Kong, we have delivered more than 200 HR Transformation projects since our founding in 2009, and were recognised as one of Singapore's Top 100 fastest-growing companies in 2025. We specialize in SAP SuccessFactors, Oracle HCM, and Workday across the full delivery spectrum: HR process design and consulting (ALIGN), technology implementation (AUTOMATE), change management and adoption (ADOPT), and managed support services (AMS).

POSITION SUMMARY

RAC is seeking a Senior Interface Developer to lead the technical integration build workstream on Oracle HCM implementations. You will architect the OIC solution, define build standards, review developer deliverables, manage the deployment pipeline, and act as the technical integration authority for both the delivery team and the client IT architecture team.

WHAT YOU WILL DO

• Architect the OIC integration solution — designing the connection strategy, error handling framework, lookup table structure, and OIC Project organisation that governs the entire integration landscape for the programme
• Define and enforce integration build standards — naming conventions, mandatory components per integration, XSL mapping standards, and the deployment checklist that every integration must pass before environment promotion
• Build and review complex OIC integration flows — personally building the architecturally demanding integrations and reviewing junior developer builds for conformance to design specifications and build standards
• Own the deployment pipeline — designing the Dev to Test to UAT to Prod promotion strategy, managing integration versioning and rollback procedures, and externalising connection parameters for clean environment promotion
• Present integration architecture and status to client IT architects — explaining design decisions with rationale, maintaining the integration risk register, and facilitating discussions about Oracle's platform capabilities and limitations in the client's enterprise context
• Build the technical handover package — integration architecture documentation, error handling runbook, connection configuration guide, OIC monitoring and alerting setup, and the post-go-live support model for integration issues

WHY ROLLING ARRAYS

RAC's Oracle HCM programmes involve complex multi-country, multi-system integration landscapes. As Senior Interface Developer, you own the integration architecture, grow a team beneath you, and are a central voice in client enterprise architecture discussions — with a clear pathway to Oracle Practice Solution Architect.

OUR CULTURE CODE

Six values define how we operate every day at Rolling Arrays:

• Thinking Smart — spot patterns, chase smarter solutions, and illuminate the path to greater productivity
• Never Stop Learning — refine and elevate skills constantly; explore the world with a curiosity lens
• Being Nice to Everyone — treat everyone with genuine warmth and respect, regardless of seniority
• Be Super Patient with Customers — exercise patience and proactivity in every client interaction
• Help Your Teammates — share the load, lighten the stress, nurture a truly collaborative team
• Acknowledge Your Mistakes — embrace mistakes as steppingstones; grow from each one

WHAT WE'RE LOOKING FOR

• 4–5 years of Oracle Integration Cloud development experience with technical team leadership or architecture ownership on at least two live programmes
• Proven OIC solution architecture capability — has designed the connection strategy, error framework, and deployment pipeline for a multi-integration engagement, not just built individual flows
• Advanced XSLT, adapter, and fault handling capability — can build and review complex integrations and identify architectural issues in junior developer builds
• Has owned integration testing cycles and managed defect resolution to UAT sign-off
• Demonstrated technical documentation and handover capability — client IT teams can maintain the system post-go-live from the documentation you produce

PREFERRED QUALIFICATIONS

• Oracle Cloud Platform Application Integration 2025 Professional — the OIC certification; at Senior level this is an expected baseline credential, not a differentiator
• Oracle Cloud Infrastructure 2025 Foundations Associate or higher — OCI services (Streaming, ATP, Functions, API Gateway, Vault) are increasingly central to enterprise Oracle HCM integration architecture
• Oracle Global Human Resources Cloud Implementation Professional — Senior integration architects who hold Core HR certification can independently make data availability decisions without functional team escalation
• Oracle Visual Builder Cloud Service (VBCS) hands-on experience — for integration requirements that extend into custom Oracle-hosted UI development

BUSINESS & CONSULTING SKILLS

• Integration architecture authority — presents solution design decisions to client IT architects with technical credibility and defends them with rationale
• Build standards governance — defines and enforces naming, error handling, and deployment standards across a developer team without creating friction
• Technical handover ownership — produces documentation that client IT teams can maintain post-go-live; handover quality is a delivery outcome, not a nice-to-have
• Developer team leadership — reviews builds, identifies architectural issues, and develops junior OIC developers through structured feedback
• Integration risk communication — translates complex technical failures into business impact language for project leadership
• Commercial awareness — understands that every re-work cycle from a poorly specified build costs the programme time and margin

CAREER PROGRESSION

Senior Consultant → Lead Consultant → Solution Architect → Practice Lead

In Oracle HCM, the difference between a well-built OTBI analysis and a poorly built one is not just formatting — it is whether the report respects the user's security context, whether it handles flattened hierarchy joins without returning duplicate rows, and whether it actually answers the HR question the business asked. If you build to that standard, this is your role.

ABOUT ROLLING ARRAYS

Rolling Arrays is a private equity-backed, award-winning HR Tech consulting firm — Asia Pacific's premium partner for enterprise HR digital transformation. Headquartered in Singapore and with offices across India, Malaysia, Australia, and Hong Kong, we have delivered more than 200 HR Transformation projects since our founding in 2009, and were recognised as one of Singapore's Top 100 fastest-growing companies in 2025. We specialise in SAP SuccessFactors, Oracle HCM, and Workday across the full delivery spectrum: HR process design and consulting (ALIGN), technology implementation (AUTOMATE), change management and adoption (ADOPT), and managed support services (AMS).

POSITION SUMMARY

RAC is hiring a Report Developer to build Oracle HCM reports and analytics using OTBI and BI Publisher. You will work with functional consultants and client HR stakeholders to translate business reporting requirements into delivered, validated reports that meet operational HR and management reporting needs — and that remain maintainable after go-live.

WHAT YOU WILL DO

• Select the correct OTBI subject area for each reporting requirement — knowing which HR data lives in which subject area, when subject areas can be combined safely, and when the requirement needs a BI Publisher SQL data model instead
• Build OTBI analyses across all HCM functional domains — Workforce Management, Compensation, Absence, Payroll, Talent, Performance, Recruiting, Learning, and Security — applying filters, calculated measures, dashboard prompts, conditional formatting, and drill-down links
• Build BI Publisher reports for all formatted output types — statutory documents such as payslips, IR8A, and CPF reports; transactional outputs such as offer letters and employment verification letters; and operational HR reports requiring pixel-perfect layout
• Test all reports against the intended user's security profile — not the admin account — validating that data scoping by Person Security Profile and Organisation Security Profile behaves correctly before UAT
• Build the report catalogue for client handover — report name, subject area, filter logic, security role required, refresh behaviour, and known limitations — at a standard that allows the client's HR team to maintain and extend reports without calling the SI
• Support post-go-live report training for client HR super-users

WHY ROLLING ARRAYS

Reporting is where Oracle HCM clients see the most immediate business value — and where poorly designed reports create the most post-go-live support noise. At RAC, report development is treated as a skill, not a task, and you will work alongside functional consultants and HR analytics leaders with a clear pathway to BI and Analytics Practice Lead roles.

OUR CULTURE CODE

Six values define how we operate every day at Rolling Arrays:

• Thinking Smart — spot patterns, chase smarter solutions, and illuminate the path to greater productivity
• Never Stop Learning — refine and elevate skills constantly; explore the world with a curiosity lens
• Being Nice to Everyone — treat everyone with genuine warmth and respect, regardless of seniority
• Be Super Patient with Customers — exercise patience and proactivity in every client interaction
• Help Your Teammates — share the load, lighten the stress, nurture a truly collaborative team
• Acknowledge Your Mistakes — embrace mistakes as steppingstones; grow from each one

WHAT WE'RE LOOKING FOR

• 2–3 years of Oracle HCM reporting experience with hands-on OTBI Answers and BI Publisher development on at least one live implementation
• Demonstrated subject area selection judgement — can explain why a given HR requirement belongs in a specific subject area and what the risk is of using the wrong one
• BI Publisher RTF template development — has built at least one formatted output report (offer letter, payslip summary, employment verification letter) on a live project
• Understanding of OTBI security behaviour — knows that reports must be tested against user security profiles, not admin accounts, and has done so on a delivered report
• Report catalogue documentation discipline — has produced handover documentation at a standard that allows client HR administrators to maintain reports post-go-live

PREFERRED QUALIFICATIONS

• Oracle Fusion Cloud Applications HCM Process Essentials certified — the foundational HCM credential; the expected starting certification at Consultant level; report developers who understand the HCM process model build more relevant reports
• Oracle Global Human Resources Cloud Implementation Professional — working toward this demonstrates that report development is grounded in Oracle HCM module depth rather than just tool proficiency
• Oracle Analytics Cloud certification or hands-on OAC experience — for programmes where OTBI is insufficient and advanced workforce analytics are in scope
• SQL proficiency for BI Publisher SQL-based data models and for diagnosing OTBI data lineage issues against Oracle HCM base tables

BUSINESS & CONSULTING SKILLS

• HR analytics communication — translates OTBI subject area constraints and data availability into language that HR Directors can use to scope reporting requirements realistically
• Security-aware delivery — tests every report against the intended user's security profile before UAT; admin-account testing is not testing
• Report catalogue discipline — produces handover documentation at a standard that allows the client's HR team to maintain and extend reports without calling the SI
• Structured requirements translation — converts an HR stakeholder's reporting request into the correct subject area, filter logic, and data model design
• Cross-functional collaboration — works alongside functional consultants to understand the data model before building, not after encountering missing fields
• Learning agility — adapts to new HCM modules and reporting subject areas across engagements without requiring extended ramp-up

CAREER PROGRESSION

Consultant → Senior Consultant → Lead Consultant → Solution Architect → Practice Lead

A Fast Formula error does not produce a support ticket — it produces a wrong payroll run affecting hundreds of employees, an incorrect accrual balance, or a benefits eligibility failure. If you write formulas to a standard where that scenario does not happen, and you have the project scars that come from knowing exactly what produces that scenario, we want to hear from you.

ABOUT ROLLING ARRAYS

Rolling Arrays is a private equity-backed, award-winning HR Tech consulting firm — Asia Pacific's premium partner for enterprise HR digital transformation. Headquartered in Singapore and with offices across India, Malaysia, Australia, and Hong Kong, we have delivered more than 200 HR Transformation projects since our founding in 2009, and were recognised as one of Singapore's Top 100 fastest-growing companies in 2025. We specialise in SAP SuccessFactors, Oracle HCM, and Workday across the full delivery spectrum: HR process design and consulting (ALIGN), technology implementation (AUTOMATE), change management and adoption (ADOPT), and managed support services (AMS).

POSITION SUMMARY

RAC is hiring a Fast Formula Developer to write, test, and maintain Oracle HCM Fast Formulas across Payroll, Absence Management, Benefits, and Time & Labor modules. You will implement business rules that cannot be met through standard Oracle configuration, translating HR and Payroll policy into validated, precisely documented Fast Formula code.

WHAT YOU WILL DO

• Assess each business rule requirement and select the correct Fast Formula type before writing — aligning formula types to the right functional context across Payroll, Absence Management, Benefits, Compensation, Time and Labor, HCM Extracts, and Core HR validation use cases
• Write and own Oracle Payroll Fast Formulas — earnings calculations, element skip rules, mid-period proration, and retrospective processing formulas, from first draft through payroll run validation
• Write Absence Management Fast Formulas — accrual calculations, carryover rules, entitlement logic, duration calculations, and plan eligibility formulas across all absence plan types in scope
• Write Benefits Fast Formulas — plan eligibility rules, coverage amount calculations, rate formulas, post-election edits, and service calculation formulas
• Write Compensation Fast Formulas — worksheet eligibility, person selection, matrix lookup, and total compensation statement item formulas
• Write Time and Labor Fast Formulas — time entry validation rules, time calculation rules, and data transformation formulas for third-party time system integrations
• Write HCM Extracts Fast Formulas — data element transformation and row selection formulas that control extract output for outbound integrations and statutory reporting
• Debug formula compilation and runtime failures — diagnosing null database item errors, context mismatches, and conditional logic failures, and resolving them across all formula types in scope
• Document every delivered formula to handover standard — business rule, variable declarations, database items referenced, version history, and known edge cases

WHY ROLLING ARRAYS

Fast Formula development is among the most specialised and highest-value technical skills in Oracle HCM. RAC's APAC programmes include real legislative payroll complexity — Singapore CPF, Malaysia EPF, Australia Superannuation — giving you implementation experience that is genuinely rare and a pathway to Oracle HCM Payroll Practice roles.

OUR CULTURE CODE

Six values define how we operate every day at Rolling Arrays:

• Thinking Smart — spot patterns, chase smarter solutions, and illuminate the path to greater productivity
• Never Stop Learning — refine and elevate skills constantly; explore the world with a curiosity lens

• Be Super Patient with Customers — exercise patience and proactivity in every client interaction
• Help Your Teammates — share the load, lighten the stress, nurture a truly collaborative team
• Acknowledge Your Mistakes — embrace mistakes as steppingstones; grow from each one

WHAT WE'RE LOOKING FOR

• 2–3 years of Oracle HCM Fast Formula development on live implementation or AMS projects — has written and deployed formulas in production, not just training environments
• Demonstrated ability to write, compile, and debug Oracle Payroll and Absence formulas independently
• Understanding of Fast Formula type selection, database item scope, and the DEFAULT block requirement
• Systematic testing approach — tests zero-value edge cases, mid-period joins, multiple concurrent assignments, and retro scenarios before declaring a formula production-ready
• Ability to translate a business rule description into a correct formula implementation without requiring a technical intermediary

PREFERRED QUALIFICATIONS

• Oracle Payroll Cloud Implementation Professional — the primary target certification for a Fast Formula Developer; the exam specifically covers payroll element architecture, balance definitions, and formula processing which are the exact domains this role works in daily
• Oracle Absence Management Cloud Implementation Professional — absence formulas are the second most common formula type after payroll; this certification demonstrates the absence module depth the role requires
• Oracle Fusion Cloud Applications HCM Process Essentials certified — the foundational HCM credential; the expected entry-level certification at Consultant level
• Singapore CPF, Malaysia EPF, or Australia Superannuation payroll formula implementation experience — APAC legislative formula expertise is the highest-demand specialism in our market

BUSINESS & CONSULTING SKILLS

• Formula documentation precision — documents every delivered formula to a standard that the support team can maintain and the client can audit without calling the SI
• Business rule translation — converts an HR or Payroll policy description into a correct formula implementation without a technical intermediary
• Payroll impact awareness — understands that a formula error affects hundreds of employees on a live payroll run; treats testing as a responsibility, not a formality
• Structured testing mindset — tests zero-value edge cases, mid-period joins, concurrent assignments, and retro scenarios before declaring production-ready
• Cross-team collaboration — works alongside Payroll Functional Consultants and Core HR team without creating specification gaps
• Learning agility — adapts to new legislative payroll requirements across APAC markets without requiring extended ramp-up on each engagement
