Role
Who you are
- 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
What the job involves
- We are looking for a Senior Software 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 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
- First 30 days: Learn the rails, ship confidently
- 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
- 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 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
- A delivered feature or 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
- 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 challenges you might tackle
- 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
- Your team's 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, Kafka
- 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
Our take
There is a lot for businesses to consider nowadays, as the evolution of the internet and technology is often hard to keep up with. Founded in 2023, Bastion is very new to the scene and sets out to enable companies to seamlessly integrate web3 infrastructure into enterprise technologies. The white-label platform uses a cost-effective product suite of tools (from custodial wallets to data analytics) for businesses to determine their on and off-chain products and further develop digital assets to better their consumers' experience.
Founded by two a16z Crypto C-suiters the platform combines the simplicity of web2 with the capabilities of web3. The company has enjoyed two impressive rounds of funding, and the premise looks promising. It will be really exciting to see how Bastion takes on competitors in the market and sets itself apart.
