## About the role

We're hiring an AI Engineer to build LLM-powered products that actually ship. You'll live at the seam between research and production — turning models, prompts, and retrieval into reliable systems users depend on. Less "train a model from scratch," more "make foundation models do useful work at scale, cheaply, and without hallucinating."

## What they're looking for

- 3+ years of software engineering, with at least 1 year shipping LLM-based features in production
- Strong Python and TypeScript, comfortable in a real codebase, not just notebooks
- Deep practical knowledge of the LLM stack: prompting techniques, function calling, structured outputs, context management, embedding models, vector search
- Have built and maintained an eval suite — and have opinions on why most public benchmarks are misleading
- Comfortable with at least one orchestration approach (custom, LangGraph, Inngest, Temporal) and one vector store (pgvector, Pinecone, Turbopuffer, Weaviate)
- Cost- and latency-aware: can read a token bill and a trace and know where to cut
