  • Proven experience improving reliability, observability, and incident response in production systems.
  • Solid background in cloud infrastructure (AWS, GCP, or Azure), including networking, IAM, monitoring, and deployment.
  • Ability to lead multi-quarter projects across teams — building consensus and delivering results.
  • Track record of mentoring engineers, setting technical direction, and raising engineering standards.
