About the role

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
