Senior Software Engineer

Bastion provides regulated infrastructure for holding, moving, and issuing stablecoins through custodial wallets, payment orchestration, and stablecoin issuance. The Senior Software Engineer will build reliable and secure services for custody, transfers, issuance, and compliance workflows, while owning service surfaces, leading cross-service initiatives, and collaborating with product, compliance, and engineering teams.

Responsibilities:

• Ramp on service architecture, CI/CD, observability, and engineering conventions
• Ship a small feature slice or quality-of-life improvement in one service
• Add tests, dashboards, or runbook notes for the areas you touch
• 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
