• Enhance our CI systems for reliability, including adaptive response to available capacity, resilience and self-recovery from outages, and highly-leveraged observability.
• Detect and isolate code breakages to minimize their blast radius.
• Work directly with product engineers to understand and deliver their productivity needs.
