About Slash
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.
About the role
Slash's stablecoin and on-chain infrastructure team builds the rails powering some of the fastest-growing surfaces of the company. We launched stablecoin payments less than a year ago and have already crossed $3B in annualized volume. Our Global USD Account is a USD account for businesses in 130+ countries, backed by USDSL, our own stablecoin issued on Base has become the entry point for thousands of businesses globally that have never had real access to U.S. dollar rails. Our Global Card lets customers spend their stablecoin balance anywhere Visa is accepted. We're hiring a product engineer to build the next chapter of all of this. You'll work on the Global USD Account, our expanded global account offerings, stablecoin payments, and the issuing stack behind the Global Card. If you want to build infrastructure where on-chain rails meet traditional banking and ship it to real businesses moving real money, this is the role.
What you'll do
Own and ship full product surfaces end-to-end across the Global USD Account, expanded global accounts, stablecoin payments, and our Global Card — from data model to API to the product customers interact with daily
Build and extend our core stablecoin infrastructure: on-chain execution, on-ramp and off-ramp orchestration, USDSL mint/redeem flows, and the settlement systems that move billions of dollars a year
Build the issuing stack for our Global Card, where stablecoin balances integrate with card rails, handling spend authorization, settlement, and the financial primitives that make a stablecoin-backed card feel as smooth as a traditional debit
Expand the Global USD Account into new markets and new use cases, giving more businesses real access to U.S. dollar rails
Work directly with customers to figure out what to build next, and partner with compliance and design to ship it correctly
We're looking for someone who
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 database migrations, and building the frontend end to end
Has strong product instincts and thinks holistically about UX, API ergonomics, and system correctness, and pushes back when something doesn't feel right
Is excited to go deep on on-chain systems, stablecoins, and the messy seams between crypto and traditional finance
Thrives working independently in a small team that ships fast
Cares about craft: writes clean, well-tested code, thinks about edge cases, and takes pride in building software that's delightful to use and correct under load
Strongly preferred
Comfortable reasoning about on-chain UX and settlement mechanics, including signing, finality, gas, and confirmation tradeoffs
Hands-on experience integrating with stablecoin on/off-ramp orchestration APIs, custody providers, or settlement infrastructure
Familiarity with cross-border money movement, FX, or treasury systems
Nice to have
Experience with Account Abstraction, smart wallets, paymasters, or multi-sig / key quorum systems
Card issuing experience, especially stablecoin-backed cards or programs built on top of issuer-processors
Background in regulated fintech — payments, banking, or compliance-heavy infrastructure
What's in it for you
Opportunity for high growth
High autonomy + ownership culture
Comprehensive health + benefits plan
Working out of our downtown San Francisco office space
Unlimited PTO
