About
Real innovation starts with a strong foundation, and at commercetools, that comes from the perfect balance of our product and our people. Behind every leap forward is a collective of builders, explorers, doers, makers, and problem-solvers. The kind of people who not only pioneered a more flexible approach to commerce architecture but also shaped the culture of experimentation that approach unlocked.
Responsibilities
•Build agent loops and orchestration: tool use, structured outputs, business-rule enforcement, graceful failure
•Build the integration layer (via MCP) that lets agents securely call backend systems and business APIs
•Render model output into live, streamed, accessible UI via generative-UI protocols
•Ground models in real data: retrieval, embeddings, and feedback loops that actually close
•Treat evals as a first-class system - provable improvement, not vibes
•Take a capability from prompt-in-a-notebook to a measured, guard-railed production feature
Requirements
•Shipped full-stack apps to production and owned them end-to-end: frontend through backend to deploy and operate, not handed off at a layer boundary
•5+ years shipping production software, 2+ building with LLMs in production (real users, not demos)
•Hands-on experience with UI protocols (A2UI, AG-UI, MCP-UI, or similar). You've built against a generative/agent-driven UI protocol, not just consumed a REST API
•The AI spine: prompt/context engineering, agents, tool use, structured outputs, evals, MCP
•Python and TypeScript/Node + React; comfortable with async, streaming, and observability
•Working fluency with retrieval/embeddings and SQL
Nice to have
•Fine-tuning/distillation, e-commerce or marketplace systems, and a track record in 0→1
