The GIS Specialist owns end-to-end GIS delivery, automation and development, and day-to-day administration of the GIS enterprise environment for AECOM's infrastructure, transportation, utilities and urban development projects. The role spans three areas: (1) core GIS delivery – spatial data production, analysis, quality control and design coordination; (2) automation and development – building and maintaining Python-based automation, geoprocessing tools and web GIS applications; and (3) GIS Enterprise administration – supporting ArcGIS Enterprise/Portal/Server,and cloud-hosted GIS environments. This is a hands-on, technically diverse role suited to a candidate who can deliver GIS outputs, build the tools that make delivery faster, and help keep the underlying GIS platform running reliably.

Key Responsibilities

GIS Delivery & Spatial Analysis

• Produce, manage and maintain spatial datasets, geodatabases and cartographic outputs for multi-discipline design teams.

• Perform spatial analysis (overlay, buffer, network, suitability) and integrate survey, design and asset data into GIS.

• Apply data standards, topology rules, QA/QC and metadata to ensure data accuracy, completeness and consistency, in line with the ISO 19100 series.

• Support design coordination, constraints mapping and options analysis, and assist with authority/client submissions.

• Manage coordinate systems, projections and transformations across local and regional datums.

Automation & GIS Development

• Design, build, test and maintain automation scripts and geoprocessing models using Python/ArcPy to streamline GIS workflows and reduce manual effort.

• Develop and support web GIS applications and dashboards using JavaScript, the ArcGIS API, Experience Builder and StoryMaps.

• Design and consume REST APIs, and write/optimise SQL queries against enterprise geodatabases.

• Build and maintain FME/ETL workflows for data transformation, migration and system integration.

• Own the full tool lifecycle – requirements, development, testing, deployment, documentation and ongoing bug-fix/maintenance support.

• Collaborate with BIM, engineering and IT teams to integrate GIS with CDE platforms (ACC/ProjectWise) and other enterprise systems.

GIS Enterprise Administration

• Support installation, configuration, upgrades and licensing of ArcGIS Enterprise, Portal and Server.

• Administer user roles, permissions and security settings across ArcGIS Online/Enterprise organisations.

• Publish, monitor and maintain map, feature and geoprocessing services; troubleshoot performance and connectivity issues.

• Support geodatabase/SDE administration, including schema management, versioning and maintenance schedules.

• Demonstrated experience developing Python/ArcPy automation and web GIS applications in a production environment.

• Working knowledge of ArcGIS Enterprise/Portal/Server administration (installation, security, service publishing) is required; hands-on administration experience is a strong advantage.

• Experience in an engineering, infrastructure or consultancy environment (transportation, utilities, urban development) preferred; Middle East experience an advantage.

• Esri certification (e.g., ArcGIS Enterprise Administration, Desktop Associate/Professional) and/or a programming language certification is preferred.

Technical Skills

• GIS platforms: ArcGIS Pro/Desktop, ArcGIS Online/Enterprise, geodatabases (SDE), ModelBuilder.

• Programming & automation: Python/ArcPy, JavaScript, ArcGIS API, REST APIs, SQL, FME/ETL.

• Integration: BIM-GIS integration and CDE platforms (ACC/ProjectWise).

• Core Microsoft Windows and Office productivity tools.

Core Competencies

• Strong verbal and written communication; able to translate technical GIS concepts for technical and non-technical audiences.

• Effective team collaboration and multi-discipline coordination.
