What You’ll Do

• Harden hosts and containerized workloads using Linux security mechanisms (AppArmor, SELinux, seccomp, cgroups) and eBPF-based tooling (Cilium, Tetragon)
• Secure containerized infrastructure across multi-cloud environments via RBAC, network policies, admission controls (Gatekeeper), and runtime threat detection.
• Build and manage automated services for Cloud Security Posture Management (CSPM), workload identity, vulnerability management, and access controls across AWS, Azure, and GCP
• Write production-quality code and leverage Infrastructure-as-Code (Terraform) to version, test, and deploy security controls as code
• Build real-time security monitoring, logging, and alerting systems to detect anomalies and track security posture at Atlas scale
• Lead initiatives across their full lifecycle; from threat modeling and architectural design to implementation, rollout, and long-term production reliability
