• Experience with caching and in‑memory data stores.
• Comfort with Docker and Kubernetes, and with deploying and debugging services in a cloud environment.
• Experience building and maintaining CI/CD pipelines.
• A habit of writing well‑tested, maintainable code, and an understanding of observability in production.
• Strong problem‑solving skills, sound judgement, and a willingness to own problems end to end.
