Strengthen security and compliance using governance, guardrails, and automated controls
Collaborate with development squads on onboarding, platform adoption, and day-to-day platform use
Drive incident response, root-cause analysis, and continuous improvement of platform reliability and support quality
Share knowledge, document standards, and establish accountable ownership for shared platform services
Support the transition of platform ownership and operational responsibility to a dedicated cross-functional/SRE team
Requirements
Extensive experience designing, operating, and troubleshooting Kubernetes in production
Strong understanding of cloud-native architectures, distributed systems, and modern infrastructure
Experience operating Amazon Web Services and Kubernetes platforms at scale
Experience designing secure, resilient, and highly available production environments
Strong understanding of Kubernetes architecture, networking, storage, security, and workload scheduling
Experience managing platform lifecycle activities (upgrades, maintenance, operational readiness)
Strong automation mindset with Infrastructure as Code and configuration as code
Experience applying software engineering principles to infrastructure and operations
Strong understanding of observability (metrics, logs, traces)
Experience integrating security, governance, and compliance into technical solutions
Benefits
Opportunity to help build and shape a central SRE capability that owns, operates, and continuously evolves Kubernetes across the enterprise.
