• Ensure least privilege/access governance: account management oversight, privileged access workflows, periodic access reviews, and audit compliance requirements
• Translate security requirements into implementation guidance that engineering teams can operationalize (clear, testable, and automatable where possible)

This position may be eligible for an increased sign‑on bonus. Eligibility, bonus amount, and applicable terms and conditions will be discussed during the recruiting process.

• Experience with vulnerability and configuration compliance workflows
• Familiarity with Linux‑based enterprise environments and common hardening concepts
• Ability to communicate risk clearly to both technical engineers and non‑technical leadership
• Strong documentation discipline
• Active TS/SCI security clearance with a current polygraph is required

Preferred Qualifications

• Experience securing or assessing containerized workflows (e.g., container runtime hardening, image governance, supply chain considerations)
• Experience with eMASS (or comparable GRC tooling), security control inheritance models, and assessor engagement
