Description

You will own the security posture and hardening of K3s environments.

Responsibilities

• Design and implement security-first cluster configurations for K3s nodes.
• Enforce mandatory access control (MAC) using SELinux and AppArmor profiles across pods and system services.
• Integrate TPM-based attestation and secure boot processes for cluster nodes.
• Define and enforce workload sandboxing strategies using SecComp, AppArmor, and SELinux contexts.
• Monitor workloads for runtime anomalies and build observability hooks for security events.

Required Skills

• Strong knowledge of K3s/Kubernetes internals, particularly security features.
• Hands-on experience with SELinux, AppArmor, seccomp, and Linux capabilities.
• Experience with TPM (Trusted Platform Module) for secure boot and attestation.
• Deep understanding of Pod Security Standards, OPA/Gatekeeper/Kyverno.
• Experience implementing RBAC, NetworkPolicies, and workload isolation at scale.
• Proficiency in Linux kernel security mechanisms and debugging.
• Familiarity with container runtimes (containerd, CRI-O, gVisor, Kata) and their security implications.
• Strong background in incident response, forensic data collection, and audit logging in Kubernetes.
• Experience integrating SBOM scanning and vulnerability management into CI/CD pipelines.

Preferred Skills

• Experience with supply chain security frameworks (SLSA, NIST 800-190).
• Hands-on with Falco or other runtime security tools.
