About the Role

We’re looking for a Full Stack Developer to build and deploy cloud applications for Generative AI within a Microsoft ecosystem. The role leans toward backend (Python or .NET on Azure), where most of the work happens, with frontend work in React/Next.js when a feature needs it end-to-end. We work across both languages, so being comfortable with either is essential and experience with both is a real plus.

You’ll own the full lifecycle of cloud services (development, deployment, monitoring, troubleshooting and maintenance) with a strong focus on practical AI solutions built around LLMs, RAG and agent-based architectures.

This is a fully remote position within Spain , ideal for someone who enjoys innovation, ownership, and working in a collaborative environment.
