Role Overview
The GIS Support Engineer provides the daily operational backbone for a production Esri ArcGIS Enterprise environment, delivering proactive monitoring, first-response incident handling, routine GIS administration, lower-complexity service request delivery, and embedded quality assurance. The role also owns operational documentation and provides on-call coverage in rotation with the rest of the technical team.
The GIS Support Engineer works closely with the Senior GIS Engineer / Tech Lead, who provides technical mentorship and code review, and escalates complex issues according to the agreed severity model.
Key Responsibilities
Daily Monitoring & Service Health
• Perform daily health checks on the ArcGIS Enterprise platform — Portal status, map service availability, REST API endpoints, and batch job runs.
• Maintain the operational dashboard; alert early on anomalies in service availability, response time, or batch job completion.
• Contribute to the 99.5% monthly system availability target through proactive monitoring and rapid first-response action.
Routine GIS Administration
• Create, author, publish, start, stop, and refresh map and geoprocessing services.
• Add, remove, and configure map layers; manage symbology, cartography, and scale dependencies.
• Create and manage cache for various layers and groups of layers; tile cache maintenance.
• Monitor and maintain spatial data currency and integrity; flag data issues to the Tech Lead.
• Optimise layers for performance; regular geodatabase compress and analyse runs as directed.
Service Request Delivery (Lower Complexity)
• Deliver service requests of smaller complexity (typically up to 3 man-days) end-to-end — analysis, implementation, testing, and documentation.
• Prepare and maintain functional specifications, design notes, user guides, and administration guides for delivered changes.
• Escalate higher-complexity service requests to the Senior GIS Engineer / Tech Lead with a clear handover.
Incident Response (Sev-2 / Sev-3 First Responder)
• Act as first responder for Severity 2 and Severity 3 incidents; acknowledge within the response window and drive initial diagnosis.
• Immediately escalate Severity 1 incidents to the Senior GIS Engineer / Tech Lead and Project Manager.
• Track and update incident progress and resolution on the client's helpdesk support platform.
• Co-operate with the client's infrastructure FM team for issues that cross the application/infrastructure boundary.
Batch Jobs & REST API Monitoring
• Monitor the scheduled batch jobs daily; raise alerts and perform first-level troubleshooting on failures.
• Perform daily REST API endpoint health checks; log response times and escalate anomalies.
UAT, Testing & Quality Assurance
• Prepare and refresh base test data sets for UAT and independent testing; support end-to-end flow testing.
• Execute test cases, log defects, track them through retest and closure, and maintain the defect register.
• Perform regression checks after service request deployments to production.
Documentation & Reporting
• Maintain operational documentation — administration guides, runbooks, service logs, and change records — after every change.
• Supply operational data (incident logs, service metrics, batch job history) to the Project Manager for the monthly progress report.
End-User Support & On-Call Coverage
• Respond to ad-hoc user queries and provide day-to-day guidance on the use of the system (approximately 20 active users).
• Participate in the on-call roster for out-of-hours support; maintain readiness to handle Emergency Service Requests.
Key Requirements
Experience (Mandatory)
• Minimum 2 years of hands-on experience supporting, administering, or developing on Esri ArcGIS software (ArcGIS Enterprise and/or ArcGIS Pro).
• Experience working within a formal service management process (incident, problem, change) with defined SLAs.
• Experience using a helpdesk or IT service management platform to log and track tickets.
Core Technical Skills
• Esri ArcGIS Enterprise (v11.x) — map services, Portal, layer publication, and basic server administration.
• Esri ArcGIS Pro — map authoring, geoprocessing, and geodatabase handling.
• Python (ArcPy and general scripting) for automation and data processing.
• Working knowledge of JavaScript, HTML, and the ArcGIS API for JavaScript for lightweight web map and widget work.
• Microsoft SQL Server basics — T-SQL queries, joins, indexing concepts, and spatial data types.
• Windows Server operations — services, tasks, logs, and basic PowerShell.
• Version control (Git), ticketing/helpdesk tools, and documentation tooling (e.g. Confluence, SharePoint, or equivalent).
Personal Attributes
• Strong attention to detail, disciplined operational habits, and a user-first mindset.
• Clear written and verbal English communication; able to document issues and solutions crisply.
• Willingness to participate in an on-call rotation and respond to out-of-hours incidents when required.
• Eagerness to learn — stays current on ArcGIS releases, SQL Server updates, and geospatial best practices.
Qualifications
• Diploma or Bachelor's degree in Computer Science, Geographic Information Systems, Geomatics, Information Technology, or a related discipline.
• Must be Singapore-based and eligible to work in Singapore.
• Able to obtain and maintain the relevant government security clearance for the engagement.
Nice-to-Have Qualifications
• Esri ArcGIS certifications (e.g. ArcGIS Pro Foundation, Enterprise Administration Associate).
• Microsoft SQL Server (e.g. Azure Database Administrator Associate) or comparable database certification.
• Exposure to .NET / C# development for ArcGIS customisations or add-ins.
• ISTQB Foundation (or similar) testing certification and experience with structured QA methodologies.
• ITIL v4 Foundation certification.
• Prior experience supporting Singapore government agencies or statutory boards.
• Awareness of OWASP Top 10 web application security risks.
• Familiarity with Government Commercial Cloud (GCC) or similar hardened cloud environments.
