Senior Backend Engineer (Python/GIS)
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 professional experience
Nice to have
- Django / Django REST Framework
- Geoprocessing pipelines at scale and large spatial datasets
- AWS, Docker, Linux
- Scrum or other agile delivery experience
- Some proven experience applying AI or GeoAI in a product
Benefits
What we offer
- Real ownership of the technical core of a product used by major utilities and grid operators
- Work that matters: Pathfinder helps speed up the infrastructure behind the energy transition
- Flexible hours around CET core time (10:00–15:00), and a choice of hybrid in Valencia or fully remote in Europe
- A small, senior, international team where your decisions ship
- An AI-forward engineering culture, with tooling and time to use it
