Use AI Tooling to write high-quality code and automated solutions that enable fast, reliable releases, reduce operational expense, and allow our infrastructure and platforms to scale thoughtfully across regions.

Evaluate the scalability, resiliency, performance, and security of production services, including testing high-availability and disaster-recovery measures and addressing potential single points of failure.

Troubleshoot complex issues across infrastructure and platform services, participate in the on-call rotation and incident-management process, and turn root-cause findings into lasting reliability improvements.

Collaborate with application development teams and other stakeholders to meet internal Service Level Objectives and customer-facing Service Level Agreements while improving the tools, frameworks, platforms, and automation used throughout the service lifecycle.
