Job Description
Bastion enables financial institutions and enterprises to issue regulated stablecoins, generate revenue on reserves, and expand their ecosystems. Bastion’s platform combines stablecoin issuance, secure custody, and seamless orchestration for cross-border transfers, on/off-ramps, and stablecoin conversions. They are looking for a Senior Backend Engineer to join their engineering team, focusing on building stable, evolvable APIs for custody, transfers, or issuance without breaking downstream clients. You'll also be building idempotent job flows for high-throughput transfers with strong audit trails, and improving p95 latency through query tuning, caching, or backpressure strategies.
The role involves owning a service surface and leading medium-scope projects to improve product metrics and reliability, and driving cross-service initiatives. The tech stack includes Go, TypeScript/Node.js, Rust (for some services), gRPC, REST, GraphQL/tRPC, Postgres, Redis, Kafka, Temporal, AWS, Kubernetes, and Terraform.
Bastion offers equity and visa sponsorship, and has a hybrid work policy with flexibility for remote work, with a preference for candidates in NYC. This is a chance to shape the technical direction of a growing startup.
