Description
About the role
We're a fast-growing W26 YC startup building the AI operating system for banks and credit unions.
We’re a team of repeat entrepreneurs, ex-VCs, ex Google/Apple ML leaders, and Math/Cyber Olympiad gold medalists. We're working directly with bank CEOs to build AI products that completely transform their business.
We're looking for founding engineers who want to build from first principles.
What we're looking for
You have shipped real products that people depend on.
More important than a specific tech stack, we're looking for engineers who:
- Figure things out without waiting for instructions.
- Enjoy owning ambiguous problems end-to-end.
- Take pride in reliably shipping software that actually works.
- Have high energy and want to build something that matters.
Experience in fintech, healthtech, or enterprise software is a plus, but not required.
What you'll do
- Build product directly with the founders.
- Design and ship AI systems used by real financial institutions.
- Own major technical decisions from day one.
- Help shape the engineering culture and the company itself.
Why join
- Very early stage with significant ownership.
- Work directly with founders every day.
- Customers already using the product to solve meaningful operational problems.
- Opportunity to define the future of AI in one of the world's largest industries.
If you're happiest when you're building, learning, and taking ownership, we'd love to talk.
