## About the role

You'll design, build, and iterate on the agents powering Santé's core merchant experience. Working on this mission-critical team, you'll develop production agent and context-layer applications — turning each store's sales history, catalog, and market context into decisions that make independent retailers money. You'll own your models from research to production, and your work ships into stores the same week.

## What they're looking for

- Apply state-of-the-art ML and LLM techniques to problems spanning:
- Document understanding (invoice OCR and structured extraction across LLM engines),
- Retrieval and ranking (embedding-based product matching on pgvector, catalog dedup, contextual recommendations)
- Build agent capabilities on top of Santé's Manager Agent platform — task generation, review workflows, and chat over each store's own data
- Build the evaluation harness for both offline and online techniques, designing experiments and metrics (evals, QA playbooks, Langfuse tracing) that provide deep insight into recommendation quality and merchant impact
- Collaborate cross-functionally with engineers, PMs, and store owners to ensure our AI drives measurable improvements in merchant revenue and hours saved
