Overview

We are looking for senior software engineers focusing on the backend to join the Bastion engineering team.

We are mostly based in New York, but are open to amazing engineers anywhere in the United States as long as you are effective working remotely.

Work to Be Done

Instead of a list of requirements, we want to give you a directional look into the first 30, 90, and 180 days on the job.

We are a startup, so the pace is fast and the specific work will change. You need to be okay with that.

If you think this is something you can handle, we will be excited to speak with you.

First 30 days: Learn the rails, ship confidently

• Ramp on service layout, CI/CD, observability, engineering conventions and practices

• Ship a small feature slice or quality-of-life improvement in one service

• Add tests, dashboards, or runbook notes for the areas you touch

• Outcomes

  • Multiple safe production deploys with follow-up verification

  • You can run core services locally and trace requests through logs/metrics

  • Updated documentation and/or PRs that improve onboarding in your area

By 90 days: Own a service surface and raise the bar

• Take ownership of a service or capability across our product, with an eye toward issuance-readiness

• Lead a medium-scope project: eg. 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

• Outcomes

  • A delivered feature/refactor that improves a product metric, SLO, or developer ergonomics

  • You’re a go-to person for your service domain

By 180 days: Drive cross-service impact

• 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

• Outcomes

  • A multi-sprint delivery that simplifies the system and unlocks product velocity

  • Clear before/after reliability or performance improvements

  • Documentation and designs that help others ship faster and safer

Some problems you might work on

• 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

Our typical stack

• Languages: Go and TypeScript/Node.js; some services in Rust as needed

• Service patterns: gRPC and REST; GraphQL/tRPC at the edge for frontend BFFs

• Data and async processing: Postgres, Redis, Kakfa

• Workflow Management: Temporal

• Infra: AWS, containers, Kubernetes, Terraform; hardware-backed key isolation with Nitro Enclaves for sensitive operations

• Observability and ops: Datadog, Grafana, Sentry, Incident.io
