About Slash
Slash is reimagining the future of business banking, helping companies prepare their financial workflows for the fundamental shifts driven by technologies like AI and crypto.
We’re building an elevated financial OS that combines the reliability of traditional banking (high yields, competitive rewards, and uncompromising security) with future-proof capabilities like stablecoins, tailored financial software, and agentic finance.
Our core tenet is a relentless focus on our customers. We serve a wide spectrum of businesses: resourceful internet entrepreneurs, traditional SMB owners, and ambitious founders building at the bleeding edge of technology. We move quickly on customer feedback—building scalable, generalizable products as well as industry-specific software that strengthens our moat within each vertical we serve.
Founded in 2021, Slash is one of the fastest-growing fintech companies in the world. We power over $10B in annual transactions across a diverse range of industries. To date, we’ve raised over $60M in venture funding, from leading investors like Goodwater Capital, Menlo Ventures, NEA, and Y Combinator.
Our team is deeply experienced yet dynamic, bringing together leaders from fintech companies like Cash App, Mercury, and Finix, alongside self-starters who have built and exited 7–8 figure businesses from their dorm rooms. Slash is headquartered in San Francisco, California.
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 an engineer to help build and evolve the core banking product — the foundation that powers Slash. 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 you’ll be doing:
Building and scaling the core banking features that moves tens of billions of dollars a year.
Working cross-functionally with product, design, and compliance teams to get the details right
Setting code-standards, shaping our engineering culture, contributing to our roadmap, and talking to customers to figure out how we can solve their problems with software.
Contributing to architecture decisions and shaping our product direction
We’re looking for someone who:
Has strong product instincts and thinks holistically about UX, API design, and system correctness
Has an intuition for financial systems or a strong desire to learn
Cares about craft, values deep technical knowledge, and delivers great product experiences.
Has experience shipping high-quality software products
Thrives working independently and in small teams in a fast-paced environment
What's in it for You:
Opportunity for high growth
High autonomy + ownership culture
Ownership of product-critical surfaces in a fast-growing fintech
Competitive pay + equity package
Unlimited PTO, Health, Vision, and Dental coverage
