Full Job Posting
Main Responsibilities
- Design and build Go microservices, model database schemas, and write migrations for the multi-tenant k0rdent AI platform.
- Design and implement durable orchestration in Temporal — idempotency, retries, timeouts, determinism constraints.
- Design public REST APIs with OpenAPI, along with multi-language SDKs.
- Build event-driven, asynchronous communication between services on a distributed streaming or message-broker platform.
- Implement authentication and authorization boundaries across an enterprise IAM platform and an API gateway — OIDC/JWT, service-to-service auth, tenant-scoped RBAC, gateway routing and rate limiting.
- Extend the identity model with standards-based user and group lifecycle provisioning (SCIM), and unify authorization between the platform's API permissions and Kubernetes-native RBAC.
- Write unit, integration, and end-to-end tests as part of every change.
- Instrument services for production — structured logging, metrics, and audit trails.
- Package and ship services with Docker, Helm, and Kubernetes.
- Review peers' code and debug incidents to root cause with regression coverage.
- Mentor junior engineers — onboarding, design guidance, and review feedback that raises the team's bar .
Required Skills/Abilities
- 10+ years of professional software engineering, including 5+ years building production backend services using Go language.
- Strong Go fundamentals: concurrency, context propagation, error wrapping, stdlib HTTP routing (Go 1.22+).
- Deep relational database experience: schema design, migrations, transactions, and query tuning under multi-tenant load.
- Track record designing versioned REST APIs consumed by external clients, and the SDKs generated from them.
- Experience building durable or event-driven asynchronous systems — workflow engines, streaming platforms, or message brokers — with idempotency and retry semantics.
