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
