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.

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

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

-

- Geoprocessing pipelines at scale and large spatial datasets

- Scrum xqbhyrx or other agile delivery experience

- Some proven experience applying AI or GeoAI in a product

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
