• Integrate and optimize CSI for persistent storage in Kubernetes workloads
• Configure and test F5 load balancing and traffic management solutions in high-traffic environments
• Conduct performance and stress testing of infrastructure and applications to identify bottlenecks across compute, storage, and network layers
• Analyze performance results, create detailed reports, and recommend optimization strategies
• Collaborate with application, operations, and security teams to validate infrastructure under realistic customer conditions
• Support hardware infrastructure (servers, switches, storage) as needed for testbed environments
• Contribute to automation, observability, and tooling for continuous performance validation

The skills you bring

• Strong experience with Kubernetes platforms (deployment, operations, and troubleshooting)
• Hands-on knowledge of Cilium or similar CNI solutions for advanced networking
• Experience with CSI drivers, ideally HPE CSI, for containerized storage management
• Solid understanding of F5 load balancers and traffic management in enterprise environments
• Background in infrastructure performance testing, benchmarking, and tuning
• Familiarity with Linux systems, containers, and CI/CD tooling
• Knowledge of physical infrastructure components (servers, networking hardware, storage systems)
• Strong problem-solving skills, with the ability to investigate complex performance issues across multiple layers

Nice to have

• Experience with observability stacks (Prometheus, Grafana, Loki, etc.)
• Familiarity with hybrid infrastructure environments (on-prem and cloud)
• Exposure to security aspects of Kubernetes and networking
