## Job Description

## 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
