Ability to build or modify security tooling in Go, Python, or Rust.
Preferred experience includes image scanning, SBOMs, secure base images, policy-as-code using Kyverno or OPA, multi-cluster environments, runtime detection, customer-facing application security testing, and AI-driven security tools.
Ability to drive technical decisions, influence security practices across teams, and collaborate in dynamic cross-functional environments.
