What you will do

• Design, build, and maintain cloud infrastructure independent of the on-premises environment.
• Architect resilient and reliable systems with security integrated into the design.
• Support production and HPC-style cloud workloads, including provisioning, scaling, performance, and cost management.
• Own networking, identity, compute, storage, monitoring, and related infrastructure end to end.
• Lead root cause analysis and improve monitoring, logging, alerting, access management, secrets management, hardening, and audit logging.
• Work with a globally distributed team to maintain high availability and address infrastructure priorities with minimal oversight.
