From validated proof of concept to production. • - Deliver MCP servers that expose data and services to AI agents and applications. • - Implement the security and authentication layer around them: enterprise authentication, custom IdP integrations, OAuth/OIDC flows. • - Consume external APIs and wrap them into services – web services, traditional APIs, or basic UIs. • - Integrate LLM providers (OpenAI and others) into client systems. • - Build semantic search and retrieval on vector databases (Pinecone). • - Query, process, and analyze data in Snowflake using SQL and Python. Prepare datasets that feed AI features and analytics. • - Contribute to data pipelines when needed. Other team members own them day to day, so this stays occasional. • - Document design decisions before implementation.

Expect a lot of querying, processing, preparing, and analyzing. • **Infrastructure and web services** • - Good fundamentals in AWS (EC2, IAM, RDS, S3 and friends), Terraform, and Docker. You don't need to be the expert in the room, but you should have real experience and know your way around. • - Experience consuming and integrating external APIs. • - Experience building web services, APIs, or simple UIs. • **General** • - 5+ years of professional engineering experience. • - Undergraduate or graduate degree in Computer Science, Engineering, Mathematics, or a similar field. • - Comfortable working in both Windows and Linux environments. Your workstation runs Windows; part of the server estate does too. • - English at C1 or above, spoken and written. • - Clear technical writing. You document decisions and ask questions before they become problems. • Extra points for • - LLM fine-tuning experience. • - Working knowledge of MCP and MCP-based integrations. • - Background in statistics or machine learning – training and evaluating basic models with scikit-learn or PyTorch. • - Experience with agent frameworks. • - Working knowledge of OAuth 2.0 and OIDC flows. • - Airflow and dbt. • - Experience with FastAPI or other Python web frameworks. • - TypeScript or JavaScript, plus Next.js or React if UI work interests you.
