## About the role

Baselayer answers questions the loan application didn't ask. For every business that crosses our queues, we need to know things that aren't on the form: what the business actually does, where it actually lives on the web, whether the people it names match the public record, and whether anything across the open web contradicts the story we were told.

## What they're looking for

- Shipped LLM-driven agents to production - not notebooks, not demos. Real users, real cost, real failure modes, real on-call
- Strong async Python including structured-data libraries, modern web frameworks, and relational databases
- Experience across multiple frontier LLM providers and at least one agent framework, with deep knowledge of failure modes
- Built or maintained eval methodology: curated golden datasets, scoring functions, labelling guidelines, regression diagnostics
- Browser automation experience: headless browsers, anti-bot evasion, authenticated flows
- Holds informed opinions on structured-output reliability - when to use JSON-schema mode vs. function calling vs. extractor-on-top-of-text
