About Position:

We are looking for a Senior Backend Developer / Architect to help design and build the next generation of our RF network planning platform. The product combines telecom domain algorithms - radio propagation modelling, antenna optimization, network prediction - with a modern cloud-native engineering stack. You will own backend services end to end: designing microservices in .NET, modelling geospatial and network data in PostgreSQL, securing APIs with Keycloak, and shipping to Kubernetes through automated CI/CD. Alongside the hands-on work, you will set technical direction, review code, and mentor engineers across the team. This role suits someone who enjoys working at the intersection of a deep engineering domain and modern distributed systems. Telecom or RF background is a genuine advantage, but it is not a prerequisite - we care more about backend and architecture strength, and we will support the right engineer in building domain depth.
