• Kubernetes Administration: Install, configure, operate, and troubleshoot Kubernetes clusters on Linux-based bare metal infrastructure, ensuring scalability, performance, and reliability.
• Kubernetes Fleet Management: Manage multiple Kubernetes clusters using standardized configurations, automated rollouts, and reconciliation processes across environments.
• GitOps & CI/CD: Design and maintain CI/CD pipelines integrated with GitOps workflows. Use Argo CD to synchronize Kubernetes environments with the desired state defined in Git, enabling traceable deployments and controlled rollbacks.
• Application Deployment: Containerize applications using Docker and deploy them to Kubernetes. Develop and maintain Helm charts and version-controlled configuration values to support repeatable deployments and controlled upgrades.
• Monitoring & Logging: Implement and maintain monitoring, visualization, logging, and alerting solutions using tools such as Prometheus and Grafana, with configuration managed through GitOps.
• Networking & Security: Configure Kubernetes Services, Ingress controllers, and Network Policies. Implement security best practices, including RBAC, least-privilege access, secure service accounts, and secrets management.
• PKI & Identity Management: Manage certificate authorities, trust chains, TLS/mTLS, and automated certificate lifecycle processes using tools such as cert-manager. Integrate enterprise identity providers through OIDC/SAML and support SSO, MFA, and centralized access control.
• Secrets Management & Governance: Integrate solutions such as HashiCorp Vault and External Secrets Operator to manage and rotate credentials securely. Maintain access policies in Git, protect sensitive data, and support auditing of access changes.
• Bosch Device & IoT Integration: Integrate Kubernetes-enabled Bosch devices into the platform management ecosystem and deploy IoT applications using Git-managed configuration and reliable data delivery mechanisms.
