Senior Software Engineer
About The Position
Bastion 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. We 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. If you want to work on hard problems in a regulated domain where your contributions matter immediately, we'd love to talk.

- Build relationships with your vertical team and cross-functional partners
- Take ownership of a service or capability across our product, with an eye toward production-readiness
- Lead a medium-scope project: updating an API contract, implementing a partner integration, or improving robustness of a critical path
- Strengthen reliability with better logging, tracing, alerts, and failure handling
- Lead a cross-service initiative, such as an API versioning plan, a data model migration, or a compliance-driven workflow change
- Shape technical direction with design docs and mentoring
- Partner with product and compliance to make pragmatic, regulation-aware tradeoffs
- Designing stable, evolvable APIs for custody, transfers, or issuance without breaking downstream clients
- Building idempotent job flows for high-throughput transfers with strong audit trails
- Hardening key operations using hardware-backed isolation and robust key policies
- Improving p95 latency through query tuning, caching, or backpressure strategies
- Navigating tradeoffs between product velocity and compliance requirements in a regulated environment
- Building services that integrate with banking partners and crypto infrastructure providers
