Here Is What You'll Do
- Encode natural language rules into code. You'll work with DSLs and novel techniques — including AI — to translate dense regulatory guidelines into executable logic. Think of it as compiling English into a system that makes six-figure decisions.
- Work side-by-side with mortgage experts. You won't be guessing what the rules mean. You'll pair with people who've spent their careers in mortgage to understand nuance, exceptions, and the "it depends" that makes this domain so hard.
- Build systems where correctness is everything. This isn't a domain where "close enough" works. You'll design for precision, build robust test coverage, and think deeply about failure modes.
- Push into uncharted territory. We're applying AI in ways the mortgage industry hasn't seen. You'll help define what's possible — not just implement what's been done before.
- Automate complex, regulated processes. Every rule you encode is a step toward a world where mortgages are faster, cheaper, and more accessible.
Tech Stack
- TypeScript
- Custom DSLs for rule encoding
- AI/ML tooling and agentic infrastructure
- NestJS + GraphQL
- SQL (PostgreSQL)
- Temporal.io (workflow orchestration)
Who Will Succeed Here
- Is deeply curious
- Wants to own features from design to development to deployment to maintenance
- Is willing to put the work in to solve the hardest of problems
