• Execution-driven mindset. You thrive in environments where you are directly responsible for delivering production-ready solutions and iterating quickly.

• Familiarity with Docker, Kubernetes, Terraform, Express, Node JS, TypeScript and GraphQL is strongly preferred.

• Passionate builder who enjoys coding, solving hard problems, and rapidly iterating toward clear goals.
