- Define and enforce workload safety standards for resource configuration, isolation, disruption tolerance, and Karpenter consolidation.
- Build automation and enforcement paths to move platform standards from onboarding through policy-enforced defaults.
- Establish observability, baseline audits, and reporting to identify hot spots and measure risk mitigation.
- Partner with cluster-user teams to understand workload needs and shape the platform.
- Drive cost and capacity strategy across node scaling, bin packing, and EC2 instance selection.
