## About the role

Slash is, at its core, a technology company and is on a mission to build the best engineering team in the world. We’re looking for a Senior/Staff Software Engineer to help build and evolve our core banking product that powers $10b in transaction volume a year. This role blends infrastructure-level thinking with deep product intuition. You’ll build fault-tolerant, user-facing financial primitives that spans across all customers, and you’ll do it fast, cleanly, and with ownership.

## What they're looking for

- Has shipped and owned full product surfaces — not just isolated features, but entire systems from data model to deploy
- Is a strong full-stack engineer: comfortable designing API endpoints, writing a database migration, and building the frontend for a project end to end
- Has strong product instincts — thinks holistically about UX, API ergonomics, and system correctness, and pushes back when something doesn't feel right
- Thrives working independently in a small team that ships fast — you're the kind of person who builds product without requiring a full spec
- Cares about craft: writes clean, well-tested code, thinks about edge cases, and takes pride in building software that is delightful to use
- Bonus: Has an intuition for financial systems (payments, ledgers, compliance) or a genuine desire to go deep on them
