About BastionBastion builds regulated financial infrastructure for modern businesses. Bastion's full stack product suite covers stablecoin issuance, custodial wallet infrastructure, and global asset conversion rails, with the flexibility to deploy individual capabilities or combine them end-to-end.Bastion's regulated foundation underpins a compliance-first approach to risk management, ensuring the integrity and security of all financial activity within its systems. Bastion holds the appropriate licenses for its own operations, but can also act as a service provider, offering compliance and financial operations support under our customers’ licenses.OverviewWe are looking for a Backend 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.You'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.This is an opportunity to build financial infrastructure at a 30+ person company where ownership is real. We're remote-first, async-by-default, and expect engineers to take initiative—whether that's shipping features, improving observability, or strengthening the codebase.
