What The Role is About

The API Experience team is responsible for Lambda’s customer-facing Core Cloud APIs — everything from creating a new instance or attaching storage to managing VPCs.

• Work directly with Superintelligence customers’ engineering teams.

• Own production features and systems, including participating in incident response rotations.

• Design and implement observability and maintenance processes for the new features we build.

You

• Backend experience building business-critical services using Python, Unix/Command line, Django or FastAPI, and Postgres.

• Proven ability to clearly communicate trade offs in scoping and timelines.

• Experience designing, implementing, and maintaining developer-facing APIs and documentation.

Additional Core Experience

• CI/CD: Automation for testing and deployment workflows

• Reliability & Observability: Logging, alerting, and building highly available systems

• Cloud Native Services: Experience with AWS, Okta, Cloudflare, etc.

Nice-to-Haves

• Experience with Kubernetes
