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
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 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
