## About the role

Agentic reperformance. Building agents that reconstruct what a statement, notice, or dispute resolution should have been from raw data — recalculating minimum payments, interest, and finance charges, then comparing against what the consumer actually received. Context engineering for regulation. Turning dense regulatory text and bank-specific test requirements into specifications an LLM-as-judge can apply consistently across populations of hundreds of thousands of records.

## What they're looking for

- This is a founding engineer role, not a specialist one. We care more about how you think than which frameworks you've memorized. The people who thrive here usually:
- Reason from first principles. A physics, math, or competitive-programming background is a strong signal — not for the credential, but for the habit of decomposing an unfamiliar problem and testing hypotheses against reality
- Are comfortable being fuzzy. Compliance is ambiguous, our roadmap moves, and you'll context-switch across regulatory domains constantly. You're someone who can hold uncertainty and still ship
- Communicate exceptionally well. This is near the top of our list. You'll work directly with banks and translate between regulation, code, and customers — clear thinking on the page and out loud matters as much as clean code
- Own problems end-to-end. Customer obsession over ticket-closing. You don't hand off at the edge of your function, you follow the problem until the customer's outcome is right
- A fintech, banking, or consulting background is a plus — regulatory familiarity shortens the ramp. But what we're really hiring for is someone who finds it interesting that a $0.09 discrepancy on a minimum payment is a finding
