What we're looking for

• Strong commercial experience developing backend applications in C# and .NET.
• Experience integrating AI or LLM technologies into production software.
• Understanding of RAG, embeddings, prompt engineering and vector search.
• Experience building scalable cloud-based applications using Azure.
• A genuine interest in Applied AI and solving real-world product problems.

What's on offer
