Responsibilities
Design and Implement Core Platform Components: Evolve our Kubernetes-based environment, focusing on areas like multi-tenancy, network policy, resource management, and service mesh integration (e.g., Istio, Linkerd)
Architect for Scale and Reliability: Lead the technical design for scaling our control plane and data plane to handle a 10x increase in services and traffic. Define and implement SLOs for the platform itself
Improve the Developer Control Plane: Design and build the next generation of our CI/CD pipelines and GitOps workflows. Drive the strategy for our internal developer portal (e.g., Backstage) to unify tooling, documentation, and service lifecycle management
