About The Team

The Citizen Developers Infrastructure team sits within the Infrastructure & Productivity organization and is responsible for the internal platform that powers critical business processes at Airwallex.

We build and operate a citizen‑developer platform that lets non‑product engineering groups safely build and run workflows and automations. Our goal is to make it easy and safe for these “citizen developers” to ship value quickly while embedding security, compliance, and software engineering best practices by default.

This role is based in Singapore.

What You’ll Do

As a Senior/Staff Software Engineer on the Citizen Developers Infrastructure team, you will design, build, and operate the platform services that underpin Airwallex’s citizen‑developer ecosystem and internal workflow automation.

You will partner closely with application teams and citizen developers to define tooling, patterns, and development processes, while continuously improving the platform abstractions and paved paths they build on. You’ll be responsible both for the developer experience and guardrails of the platform, and for the underlying workflow infrastructure that makes it reliable and scalable.

Responsibilities

• Design, build, and evolve the citizen‑developer platform and tools that make it easy to create and operate automation / applications without deep infrastructure knowledge.

• Establish secure SDLC and guardrails for citizen‑developer‑built applications so compliance and security are baked in by default.

• Build self‑serve development and operations tooling that reduce dependence on central platform engineers.

• Design, build, and maintain the Temporal‑based workflow infrastructure, addressing challenges such as multi‑tenancy, high availability, and cost effectiveness.

• Contribute to the Kubernetes and GitOps foundation (ArgoCD, Helm, Terraform) that powers the platform, ensuring deployments are safe, repeatable, and auditable.

• Participate in code reviews, technical design discussions, and on‑call rotation for workflow‑related services, leading incident response and driving long‑term fixes where needed.

• Document standards, best practices, and reference architectures so teams building on top of the platform have clear, self‑serve guidance.

Who You Are

You are a backend/platform engineer who enjoys building shared platforms, cares deeply about developer experience, correctness, and operability, and is comfortable working at the intersection of application code and infrastructure.

You get energy from enabling other teams to move faster safely, through well‑designed abstractions, tooling, and guardrails.

Qualifications

• 4+ years of experience in Software / Platform Engineering roles, building and operating backend or platform services in production.

• Strong hands‑on experience with at least one strongly typed backend language (e.g., Golang, Java) and familiarity with Python or Bash for tooling/automation.

• Experience designing and building internal platforms or developer tooling used by multiple teams, with a strong focus on developer experience.

• Experience with Kubernetes and GitOps practices/tooling (ideally ArgoCD and Terraform).

• Experience building platforms or tooling for non‑product engineering users (e.g., operations, finance, analysts) or low‑code/no‑code / citizen‑developer environments is a strong plus.

• Proven experience with Temporal or similar workflow/orchestration systems (e.g., Cadence, Step Functions, Airflow) or large‑scale stateful workloads (e.g., Redis clusters, Cassandra, HBase) in production is a huge plus.

• Comfortable working in highly collaborative, multi‑team environments, able to translate platform constraints into clear APIs, contracts, and paved paths for application teams and citizen developers.

• Practical, proactive problem solver who can navigate ambiguity, break down complex technical problems, and drive them to closure.

• Equity: VIMA-Compliant Option Pool Allocation Available.

Position Overview

OmniSyn SG is recruiting a founding Lead Enterprise &Security Architect to steer the technical deployment of our real-time national healthcare financial clearinghouse utility.

You will own the absolute design sovereignty of ahigh-performance network that connects corporate HR platforms, major brokerage networks, primary clinical terminals, and Tier-1 insurance carriers across Singapore.

Your core mandate is to ensure our Lean Steel Thread microservices pipeline continuously delivers sub-50ms transactional clearing latency while strictly satisfying MAS FinTech Sandbox Plus, PDPC, and Health Information Act (HIA) 2026 data residency parameters natively at the perimeter edge.

Core Responsibilities

1. System Topology & Infrastructure Design

• Architect and maintain a secure Hybrid Edge Cloud Topology utilizing local Singapore cloud boundaries (AWS ap-southeast-1 or GCP Singapore).
• Isolate public-facing perimeter nodes from air-gapped backend vaults housing our core relational schemas.

2. High-Velocity Message Streaming & Security Proxy Governance

• Configure and tune Kong API Gateway OSS instances in DB-less Mode using static local YAML schemas to eliminate database bloat.
• Mount and manage perimeter protection plugins, including hmac-auth signature checking and custom Token Bucket rate-limiting configurations.
• Design and supervise multi-topic Apache Kafka event message stream buffers to process unstructured payload spikes asynchronously without system timeouts.

3. Rules Engine Adjudication & Micro-Ledger Structuring

• Oversee the data object model matching framework feeding our in-memory Java-based Stateless Drools Engine.
• Ensure declarative rules perfectly parse and compute complex financial-grade variables, including MOH Private Fee Benchmarks, 5% co-payment splits, and rolling annual out-of-pocket ceilings.
• Structure highly optimized PostgreSQL relational micro-ledger tables using hardware-level AES-256 partition encryption filters.

4. Identity Ecosystem & Integration Governance

• Own the technical implementation of GovTech’s Singpass OpenID Connect (OIDC) 3-legged authentication loop.
• Enforce absolute privacy boundaries by mapping users via unique, system-generated 128-bit UUID hashes, completely removing raw NRIC numbers from database records to satisfy regulatory audits.
• Architect hands-free transactional synchronization pipes directly linking system outputs to the platform's Xero automated invoicing API gateway.

Technical Profile & Prerequisites

• Experience: 7+ years directing core software architectures within high-volume FinTech processing environments, clearinghouse utilities, or medical-grade data exchanges.
• Runtime Languages: Advanced engineering fluency across Java (for Drools rules environments), Node.js, or Python microservices.
• Infrastructure Domain: Expert mastery of Kong Gateway setups, Apache Kafka clustering topologies, Docker environments, and PostgreSQL index optimization.
• Identity Tech: Deep operational knowledge of OAuth 2.0, FAPI 2.0, and OpenID Connect protocols (prior deployment inside GovTech Singpass Developer staging environments is highly valued).
• Regulatory Vetting: Proven experience passing institutional technical audits under MAS TRM (Technology Risk Management) guidelines or state healthcare data frameworks.
