What will you own

You will work across the agent runtime, RAG, memory, evaluation, and the Studio as part of the senior engineer track. You will be responsible for building reference agents, the knowledge-base pipeline,

evaluation datasets, and driving pilot feedback initiatives. This role focuses on the areas of the product where AI quality, performance, and user outcomes are defined.

Responsibilities

- Implement features end to end — API, data model, tests, telemetry — from a design agreed with your track lead
- Build and tune agents: prompts, tool schemas, structured outputs, routing rules; measure them with the eval harness rather than by feel
- Own the knowledge-base pipeline (ingestion, chunking, embedding, retrieval quality) and the memory features
- Contribute to the Studio (React / TypeScript) when your feature needs a UI

Must Have

- Strong Python with modern tooling (typing, Pydantic, async,



pytest); can work in TypeScript /

React when needed

- Hands-on with LLM APIs: tool / function calling, structured outputs, prompt iteration, token and cost awareness; has shipped at least one LLM-powered feature to real users
- Built a RAG pipeline or search feature: chunking, embeddings, a vector database, retrieval evaluation
- Comfortable with PostgreSQL and Redis; understands REST API design and event-driven basics
- Works with Docker, Git and CI daily; writes tests without being asked
- Curious and rigorous: reads model behaviour from traces, forms a hypothesis, tests it

Good to Have

- Experience with LangGraph or other agent frameworks
- Experience with Temporal
- Familiarity with Kubernetes
- Experience building evaluation datasets or implementing LLM-as-a-Judge methodologies
- Prior experience working on enterprise integrations
