About the job GIS Technical Advisor - DTS
057 The GIS Technical Advisor is a senior, hands-on role responsible for providing technical leadership and advisory support to a multi-disciplinary project team delivering a modern Spatial Data Infrastructure (SDI) and Geographic Information System (GIS) solution.
This role will play a critical part in replacing and modernizing legacy GIS platforms, ensuring that geospatial requirements are well-defined, technically sound, and aligned with enterprise architecture and public-sector standards. The GIS Technical Advisor contributes across the full project lifecycle—from discovery and solution design through implementation, migration, testing, and transition to operations.
This is an advisory and delivery-focused role, emphasizing practical implementation guidance, risk mitigation, and knowledge transfer rather than ongoing system operations.
Key Responsibilities Provide expert GIS architecture and technical input during project initiation and planning, including scope, risks, dependencies, and constraints
Support the development and review of key project artefacts, including technical approaches, architecture designs, implementation strategies, and migration plans
Advise on options for modernizing and replacing legacy GIS systems, including platform selection, integration considerations, and technical feasibility
Guide the design and configuration of the target GIS solution to align with business needs and enterprise standards
Define GIS data models, layers, metadata standards, and data quality requirements
Provide recommendations on out-of-the-box configuration vs. customization, ensuring sustainable and maintainable solutions
Review vendor deliverables and technical designs to ensure alignment with project requirements and spatial analysis needs
Advise on geospatial data migration strategies, including data cleansing, transformation, validation, and quality assurance
Identify risks related to legacy data structures and recommend mitigation strategies
Support testing and validation of migrated data to ensure accuracy, completeness, and usability
Perform or advise on spatial analysis and mapping requirements to validate solution capabilities
Translate complex GIS concepts into clear, actionable guidance for both technical and non-technical stakeholders
Contribute to technical documentation, standards, and knowledge transfer materials
Ensure alignment with data governance, security, and quality standards within a public-sector environment
Support the establishment of GIS best practices, processes, and controls to minimize technical debt and operational risk.
Qualifications & Experience Degree or diploma in GIS, Geography, Geomatics, Spatial Sciences, Computer Science, Engineering, or a related field
GISP (Geographic Information Systems Professional) designation is considered an asset
Up to 10 years of experience as a GIS Architect or GIS Developer with hands-on involvement in GIS/SDI implementations or major system upgrades
Demonstrated experience supporting large-scale SDI initiatives, particularly involving legacy system replacement
Strong knowledge of commercial and/or open-source GIS platforms (e.g., ESRI ArcGIS or equivalent)
Experience designing GIS and SDI architectures using ArcGIS Enterprise within secure, regulated environments
Experience building GIS services and SDI components for high-demand, scalable environments
Strong programming skills in Python, including experience with ArcGIS API for Python
Experience designing and implementing metadata strategies to support SDI governance
Proven ability to communicate complex technical concepts clearly to diverse stakeholders
Experience working in public sector or large enterprise environments with multiple stakeholders
Strong analytical, documentation, and problem-solving capabilities
