- Prior hands-on experience shipping core security platforms such as Vault, SPIFFE/SPIRE, eBPF sensors, or just-in-time access engines.
- Ability to analyze complex cloud and on-premise architectures, isolate blast radiuses, and eliminate execution risks.
- Deep knowledge of Linux kernel security, container runtimes, Kubernetes, IAM frameworks, PKI, GPUs, switches, bare-metal systems, and infrastructure orchestration.
