About the Role

We’re looking for a Middle Full-Stack Developer to build and deploy cloud applications for Generative AI within the 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.
