Job Description
About Bastion
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.
Overview
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.
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.
This role is based out of our New York City office. We work in a hybrid-but-flexible way (no set days in the office, come in when you think its effective, travel when you like). As a result, we are also open to remote candidates.
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
Outcomes
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
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 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
