Software Engineer, Stablecoin

About the 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 is why we are creating a new category of business banking. We combine the reliability of traditional banking with high yields, competitive rewards, and comprehensive security alongside industry-specific features that make businesses more efficient, more competitive, and more profitable. Slash is hiring a product engineer to build the next chapter of all of this. You will own and ship full product surfaces end-to-end across the Global USD Account, expanded global accounts, stablecoin payments, and our 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. You will build and extend our core stablecoin infrastructure: on-chain execution, on-ramp and off-ramp orchestration, USDSL mint and redeem flows, and the settlement systems that move billions of dollars a year.

Key facts

What you'll do

You will 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. You will build and extend our core stablecoin infrastructure: on-chain execution, on-ramp and off-ramp orchestration, USDSL mint and redeem flows, and the settlement systems that move billions of dollars a year. You will 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. You will expand the Global USD Account into new markets and new use cases, giving more businesses real access to U.S. dollar rails. You will work directly with customers to figure out what to build next, and partner with compliance and design to ship it correctly. You will translate ambiguous product requirements into robust technical solutions, collaborating closely with design, compliance, and other stakeholders to deliver high-quality features on schedule. You will ensure system reliability, performance, and security at scale, monitoring production behavior and iterating on improvements to meet the needs of a rapidly growing business. You will contribute to a culture of craftsmanship by writing clean, well-tested code, documenting your work, and sharing knowledge across the team. You will participate in code reviews, debugging complex issues, and mentoring less experienced engineers where appropriate.

Requirements

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.

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 is delightful to use and correct under load. Comfortable reasoning about on-chain UX and settlement mechanics, including signing, finality, gas, and confirmation tradeoffs. Has hands-on experience integrating with stablecoin on and 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.
