6 Months Intial contract

Role Purpose

We are seeking an experienced GIS Developer to play a key role in delivering high-priority geospatial data migration and modern web GIS applications. Working within an Agile delivery team, you will design, build, and support customer- and internal-facing spatial systems using ArcGIS Experience Builder, write robust spatial ETL pipelines with FME Workbench and Python, and deliver clean, well-tested code integrated via Azure DevOps CI/CD.

Key Responsibilities

• Application and Platform Development: Design, build, and maintain intuitive web mapping applications and spatial dashboards using ArcGIS Experience Builder and modern web technologies.
• ETL and Data Migration: Lead and execute complex geospatial data transformation and migration workflows using FME Workbench, Python (ArcPy, GeoPandas, Shapely), and SQL.
• Engineering Standards and Delivery: Write clean, modular, maintainable code backed by automated testing strategies and API documentation (Swagger/OpenAPI).
• Agile Collaboration: Actively participate in Scrum ceremonies, backlog refinement, peer code reviews, and quarterly Program Increment (PI) planning sessions.
• Pipeline Integration and Operations: Work with Azure DevOps pipelines to support CI/CD deployments; monitor application performance, troubleshoot incidents, and contribute to occasional out-of-hours support if required.

Mandatory Technical Skills

• Proven track record developing with ArcGIS Experience Builder (custom widgets, themes, and configuration).
• Advanced expertise in FME Workbench / FME Server (Flow) for enterprise-scale spatial ETL and batch data transformations.
• Strong background in geospatial data migration projects (schema mapping, data cleansing, validation, legacy-to-modern platform transitions).
• Strong programming experience in Python applied to spatial analysis and automation.
• High proficiency in SQL (spatial indexing, relational queries, PostGIS, MS SQL, or Oracle Spatial).

Secondary / Working Knowledge

• Practical experience within Azure environments and Azure DevOps (pipelines, repos, work item tracking).
• Experience documenting APIs using Swagger / OpenAPI standards.
• Familiarity with formal test strategies (unit testing, regression testing, automated UI/data tests).
• Understanding of SAFe / Agile delivery concepts, including PI Planning cadence.
