Job description

GIS Solution Architect (Enterprise Geospatial Platforms)

Are you a GIS specialist who enjoys shaping the architecture behind large-scale geospatial systems? We're looking for an experienced GIS Solution Architect to provide technical leadership and architectural oversight for enterprise GIS platforms — spanning architecture design, cloud migration, system modernisation, security, integration, and day-to-day operational support. You'll play a key role in keeping these platforms reliable, scalable, and future-ready.

What you'll do

• Provide technical leadership and architectural oversight across enterprise geospatial platforms and related systems.
• Drive architecture design, cloud migration, system upgrades, infrastructure modernisation, and operational readiness.
• Plan and execute platform upgrades, cloud migrations, system refreshes, disaster recovery exercises, and infrastructure security initiatives.
• Evaluate and recommend technology solutions aligned with government technology directions — cloud adoption, enterprise architecture standards, cybersecurity, secure-by-design principles, and modernisation of legacy systems.
• Design and support cloud-native and hybrid GIS architectures on AWS, Azure, GCC, or equivalent.
• Design integration patterns using REST APIs, web services, SFTP-based data exchanges, authentication/identity management, and system-to-system integrations.
• Manage geospatial data architectures — geodatabases, spatial data models, metadata, data governance, and data lifecycle.
• Conduct technical assessments, solution reviews, sizing exercises, root cause analysis, and troubleshooting of complex application and infrastructure issues.
• Manage vendors and service providers across implementation, upgrades, support, and service delivery.
• Translate business and technical requirements into practical, scalable, sustainable GIS solutions.

What you'll bring

• Degree or Diploma in Computer Science, IT, Geomatics, GIS, Engineering, or a related field.
• Minimum 5 years' experience as a Technical Lead, GIS Solution Architect, GIS Engineer, or equivalent, covering geospatial systems design, implementation, operations, and modernisation.
• Hands-on delivery of enterprise GIS projects across the full lifecycle — requirements, architecture, implementation, testing, migration, deployment, and operations.
• Strong knowledge of enterprise GIS platforms, preferably Esri ArcGIS Enterprise (Portal for ArcGIS, ArcGIS Server, Data Store, Web Adaptor, Experience Builder, Dashboards, ArcGIS Online, ArcGIS Pro).
• Experience supporting production-critical GIS platforms with high availability, security, monitoring, backup, disaster recovery, and performance optimisation.
• Strong grasp of government security, compliance, and governance requirements — risk assessments, security reviews, and operational readiness.
• Excellent stakeholder management and communication skills, both written and verbal, with the ability to engage technical teams, senior management, vendors, and business stakeholders.

Technical skills

• Enterprise GIS: ArcGIS Enterprise, Portal for ArcGIS, ArcGIS Server, Data Store, Web Adaptor, Experience Builder, Dashboards, ArcGIS Online, ArcGIS Pro
• Cloud & Infrastructure: AWS, Azure, GCC, GCC+, hybrid architectures, high availability, backup, disaster recovery, performance optimisation
• Integration: REST APIs, web services, SFTP data exchanges, authentication/identity management, WOG AD, IAM, SSO, API security
• Databases & Geospatial Data: PostgreSQL/PostGIS, SQL Server, Oracle, geodatabases, spatial data models, metadata management, data governance
• Standards & Formats: feature/map services, WMS, WMTS, WFS, GeoJSON, shapefiles
• Automation: Python, ArcPy, geoprocessing workflows, GIS automation

Nice to have

• ArcGIS Enterprise administration and troubleshooting, including on AWS/GCC+ environments.
• Experience with geospatial platform migrations and cloud transformation projects.
• Exposure to government geospatial platforms and inter-agency data-sharing initiatives.
• Experience managing geospatial products and services used across multiple agencies and external stakeholders.
• Familiarity with government security policies and compliance for spatial data and enterprise systems.
