• Develop, maintain, and support our own Docker-based workloads.
• Own the product deployment and upgrade process end to end.
• Support and troubleshoot running customer-facing services.
• Work 50% of your time with our product teams, ensuring much-needed improvements get defined, explained, worked on and rolled out.
