Our platform combines custodial wallets, global payment orchestration, and stablecoin issuance. Customers can use each product independently or connect them into a single end-to-end flow.\nWe operate through our own regulated entities, with compliance and risk controls built directly into the platform. We can also support customers operating under their own licenses with the compliance and financial operations required to run their programs.\nOverview\nWe are looking for a Senior Software Engineer to join our engineering team and build the core infrastructure that powers our stablecoin platform. In this role, you'll design and ship services that handle custody, transfers, issuance, and compliance workflows-systems that process real money and require exceptional reliability and security.\nYou'll work within one of our product verticals (Custody, On/Off Ramps, Issuance, or Shared Services), collaborating closely with product managers, compliance, and other engineers. Our teams are small and cross-functional, which means your work ships fast and has direct impact on customers and partners.\nThis is an opportunity to build financial infrastructure at a 30+ person company where ownership is real. We expect engineers to take initiative. Whether that's shipping features, improving observability, or strengthening the codebase. If you want to work on hard problems in a regulated domain where your contributions matter immediately, we'd love to talk.\nWork to Be Done\nInstead of a list of requirements, we want to give you a directional look into the first 30, 90, and 180 days on the job.\nWe are a startup, so the pace is fast and the specific work will change. You need to be okay with that.\nIf you think this is something you can handle, we will be excited to speak with you.\nWe are building out our engineering hub in New York City, and this role is based our of our SoHo office.
