Strong experience with infrastructure as code, GitOps, CI/CD workflows, and modern deployment practices. Strong command of observability and reliability fundamentals across metrics, logging, tracing, alerting, and incident response. A track record of leading through influence, making sound technical decisions, and raising the bar across engineering teams.

Experience supporting cloud or multi‑cloud environments with a focus on resilience and scale. Comfort with TypeScript or Python for internal tooling and operational automation. You'll thrive here if you... Embrace AI as a core tool for problem‑solving, creativity and scale. Show a strong work ethic, high ownership and bias toward action.
