Here Is What You'll Do
- Define what a mortgage is in code. Seriously. You'll work on semantic models that don't just represent mortgages as they exist today — they expand what a mortgage can be. This is product design at the API layer.
- Build toward an event-driven API. We're moving to a world where our API doesn't just respond to requests — it tells you what happened, why, and what you can do next. You'll help design and ship that future.
- Make the complex feel simple. Our API should make the mortgage process impossible to get wrong. That means thoughtful abstractions, clear documentation, and an obsessive focus on developer experience.
- Design for nonlinearity. Mortgage flows aren't linear wizards. Our future API encodes choice, branching, and path-dependence natively. You'll work on guided experiences that model real-world complexity without exposing it as chaos.
- Treat this as a product surface. You'll think about breaking changes, versioning, onboarding, and the full lifecycle of an API that real companies depend on.
Tech Stack
- TypeScript
- GraphQL (this is the product)
- NestJS
- SQL (PostgreSQL)
- Temporal.io (workflow orchestration)
- Event-driven architecture
- AI-driven development tooling and agentic infrastructure
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
