• Design and Implement multi-region deployments, such as BigTable clusters spanning multiple regions, with strategies to ensure specific customers are routed to designated regions (e.g., sticky sessions at the regional level).

• Solve complex problems that arise from our unique data volume and request rate which may involve digging deep into data store and messaging internals

• Optimize local development and testing workflows to be fast, efficient, and seamless.

• Design and implement services and libraries for components to interact with data stores, messaging layer and services platform

• Develop tools for monitoring, detecting faults, and automatically repairing distributed systems

• Provide design support to internal engineering teams for optimal usage of data stores, data growth planning, production workload optimization, messaging, caching and service platform

• Participate in on-call support and incident response activities, providing 12/7 coverage for one calendar week approximately once every 3-4 weeks.
