Senior/Staff Software Engineer role to build and evolve core banking product handling $10b yearly transaction volume.
Responsibilities
- 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.
Other
- 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.
- Own and ship entire product surfaces end-to-end, from database schema and API design to building the product customers interact with daily
- Build and scale our core financial infrastructure: payments, transfers, invoicing, bill pay, onboarding, and card management systems that move tens of billions of dollars a year
- Design data models, write migrations, and build the backend services that power complex multi-step financial operations
- Work directly with product, design, and compliance to ship features that are correct, compliant, and actually good to use — in financial software, the details are the product
- Shape engineering standards, contribute to architecture decisions, and talk to customers to figure out what to build next
- 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
- Opportunity for high growth
- High autonomy + ownership culture
- Comprehensive health + benefits plan
- Working out of our downtown San Francisco office space
- Unlimited PTO
