About Gilytics
Gilytics is a Swiss geospatial SaaS company. Our platform, Pathfinder, helps utilities, grid operators and infrastructure planners find the best routes and sites for new infrastructure, turning months of manual planning into a data-driven, transparent process. We are a remote-first team of about 26 people across Europe and the Americas.
The role
We are looking for a Backend Lead to own the server-side engine behind Pathfinder: the geoprocessing, spatial data APIs and backend services our customers rely on. This is a hands-on senior role. Depth of knowledge and an ownership-driven, collaborative attitude matter more to us than years in a management title.
You will report to our CTO, Salvador Bayarri, and work closely with the Frontend, DevOps and GIS Data teams.
Tasks

What you will do
Architect and build the backend data model, REST APIs and services behind Pathfinder
Develop, optimise and maintain geoprocesses and spatial data functions
Set backend priorities with the CTO and run agile delivery for the team
Lead code reviews and set the standards for testing,



documentation and security
Mentor and grow backend developers
Integrate AI into the backend (model endpoints, MCP servers, AI agents) and champion AI-assisted development across the team
Contribute to product roadmap planning and technical estimation
Requirements

What you bring
5+ years of professional software development, primarily backend
Strong Python, including GIS libraries such as GEOS, GDAL/OGR, Shapely or GeoPandas
Hands-on experience building geospatial applications with PostgreSQL/PostGIS
A track record of designing and maintaining REST APIs and scalable backend services
Technical leadership experience: coordinating developers, reviewing code and mentoring, whether or not you held a formal management title
Good knowledge of Git, automated testing and CI/CD
Professional working English
A degree in Computer Science, Software Engineering, GIS/Geoinformatics or similar, or equivalent pro
