Overview

We are looking for (very) 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

Youre 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
