• OCI Bundle Orchestration: Manage packaging, distribution, and lifecycle of application bundles in OCI-compliant registries for edge environments.
• Helm Expertise: Build, optimize, and maintain Helm charts for application packaging and upgrade automation.
• Security & Networking: Enforce security best practices, network segmentation, and zero-trust principles throughout platform design.
• Upgrade Strategy: Define and execute robust cluster and platform upgrade strategies to ensure long-term stability and security.
• Collaboration & Leadership: Partner with product, security, and engineering teams; mentor junior engineers; and establish technical standards.
• Documentation & Communication: Create clear documentation of architectures and processes while effectively communicating to technical and non-technical audiences.

• Deep hands-on expertise with upstream Kubernetes, RKE2, and Rancher Gov stack.
• Proven experience implementing GitOps workflows with Fleet and/or ArgoCD.
• Strong knowledge of OCI bundle management, Helm packaging, and orchestration pipelines.
• Expertise in secure infrastructure design, networking, and segmentation strategies.
• Demonstrated success in leading teams or initiatives delivering end-to-end platform solutions.
• Solid background in CI/CD, containerization (Docker, Kubernetes), and Linux systems.
• Excellent problem-solving, communication, and leadership skills with the ability to influence across teams.

Nice to Have
