About the role

Work to Be Done

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

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

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

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
