About the role

Key responsibilities & impact

You own AI capabilities end-to-end: from the data and context that feed a model, through agent orchestration, to the generative UI a user sees and trusts.
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
Take a capability from prompt-in-a-notebook to a measured, guard-railed production feature

Requirements

What you’ll need

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
