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
More about this role
Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate. That's why we're creating a new category of business banking. We combine the reliability of traditional banking (high yields, competitive rewards, and comprehensive security) with industry-specific features that make businesses more efficient, more competitive, and more profitable.
Started in 2021, Slash is one of the fastest growing fintechs in the world and we power over ten billion dollars a year in business purchasing across numerous industries. We recently raised a $100M Series C led by Ribbit Capital with participation from Khosla Ventures, Goodwater Capital, NEA, and Y Combinator, accelerating our expansion into new markets and products.
Slash is headquartered in San Francisco, and has a strong in-person culture.
