1. Context

Digit’Eaux is the sector-specific entity responsible for providing shared IT services to public water operators in Wallonia.

It designs, operates, and evolves a sectoral GIS platform based on Esri technologies (ArcGIS Pro, ArcGIS Enterprise, Utility Network, Field Maps, Survey123, Dashboard, etc.), PostgreSQL/PostGIS, FME Desktop & Flow, and integrates numerous business processes related to the management of drinking water supply and sanitation networks. Digit’Eaux must ensure the continuity and evolution of its services, while supporting the cooperators in their strategic projects, following a logic of resource sharing, consistency, and increasing sector maturity.

To support the realization of transformation projects as well as the ongoing and corrective maintenance of solutions, Digit’Eaux wishes to strengthen the team with GIS Experts. The experts may be complementary and will be able to intervene in the functional analysis of business needs, the design, development, and configuration of appropriate geospatial solutions, as well as their ongoing and corrective maintenance, while ensuring quality, performance, security, and documentation.

2. Missions

Their missions include, among others, the following tasks:

• Leading user workshops;
• Challenging business requests to ensure consistency, viability, and added value;
• Working closely with architects to align needs and feasibility;
• Producing detailed functional specifications by precisely formalizing business rules, use cases, and acceptance criteria;
• Structuring requirements in a rigorous and prioritized manner;
• Modeling processes (UML/BPMN) and data flows (ArcGIS/UN/PostgreSQL/FME);
• Preparing test scenarios and supporting UAT;
• Contributing to change management, user guides, and documentation for deployment and operation;
• Developing/configuring ArcGIS apps (Experience Builder, JavaScript API, Field Maps, Survey123) and publishing services/layers in ArcGIS Enterprise;
• Performing unit tests, corrective actions, and documenting code and scripts;
• Designing/optimizing FME Desktop/Flow workflows (scheduling, monitoring, recovery);
• Integrating web services (REST/OGC) and PostgreSQL/PostGIS data;

Skills

Experience:

• Higher education in geomatics, geography, computer science or equivalent (minimum Bac+4/5);
• Minimum 10 years of experience in functional analysis in a GIS context and/or in GIS development on the Esri ecosystem;

Skills:

• Experience in leading workshops and drafting functional documents;
• Ability to communicate with non-technical profiles;
• Skills in modeling geographic data (MCD, MLD);
• Proficiency in UML and BPMN;

• Mastery of the ArcGIS suite:

• ArcGIS Pro: advanced understanding of models, rules, domains, topology.

• ArcGIS Enterprise: service publishing, portal management, user management, optimization via tiling, administration (federations, Data Store, security, dedicated/shared instances, etc.)

• Expertise in configuring ArcGIS Experience Builder, Survey123, Field Maps, and ArcGIS Dashboards;

• Proficiency in Python (ArcPy) for automation of geospatial processing and/or deployments;
• Utility Network: solid knowledge of concepts (associations, rules, tracing, topology), ability to analyze functional impacts;
• Mastery of FME Desktop/Flow: creation of standard workflows (simple transformers) is a MUST / complex automations, FME Flow, logs & debugging is an asset;
• Proficiency in SQL / PostgreSQL / PostGIS: solid command of spatial databases, operational command of SQL, joins/aggregations, basic spatial functions (ST_Intersects, ST_Buffer…), spatial indexes;
• Notions of DevOps (Git, CI/CD, deployment on ArcGIS Enterprise);
• Proficiency in French;
• Knowledge of technical English required;
• Esri certifications (ArcGIS Enterprise Administration, Utility Network, Desktop Associate or Professional) and FME (Certified Professional) are considered assets;
• Demonstrated experience in GIS projects related to the water/sanitation sector (knowledge of business processes and practices of public operators) is an asset.
