• Enable effective self-service by turning platform capabilities into reusable abstractions.

You have...

• Strong problem-solving skills and experience delivering and shipping pragmatic solutions in production environments.
• Experience with distributed systems fundamentals (networking service-to-service communication failure modes caching/storage concepts).
• Experience working on production systems (through industry roles internships or substantial open-source work).
• Experience with one or more CI/CD tools (Jenkins Argo CD GitHub Actions) and infrastructure management tools (Terraform CloudFormation)
• Clear written and verbal communication skillscomfortable writing docs/runbooks and collaborating across teams.
