Software Engineer, Stablecoin

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.
