Water infrastructure engineering and GIS mapping for sustainable cities

Environmental Services Venelles 51–200 employees Founded 1989 Privately Held

Altereo is a 30+ year-old French engineering consultancy focused on water systems, urban planning, and climate resilience. The stack—heavy on geospatial tools (QGIS, ArcGIS, PostGIS, GeoServer, OpenLayers) plus core backend (Python, Java, Spring)—reflects a business built around spatial analysis and data visualization for infrastructure clients. Hiring is engineering-dominant (67 of 72 active roles), with senior-level preference, signaling deep technical project work rather than rapid scaling.
