Job summary

Anduril Industries in Chantilly, VA, seeks an Assistant Contractor Special Security Officer — Program Integration (ACSSO-Program Integrator) to lead security program management for classified programs embedded with the Westfield government program security office.

You will bridge IT deployment with government security needs, driving accreditation, scheduling, and documentation while coordinating with CSOs and Authorizing Officials.

Qualifications

• Active TS/SCI security clearance (CI Polygraph preferred).
• 3–5 years of ACSSO or similar role in security operations within classified environments.
• Demonstrated understanding of ICD 503 and NIST SP 800-53.
• Detailed familiarity with system accreditation processes, POAMs management, and security documentation (SSPs, SCTG, etc.).
• Experience coordinating with government security counterparts and Authorizing Officials.

Responsibilities

• Serve as the designated security point of contact for all program teams, IT deployment teams, and system administration groups — ensuring every technical change, system deployment, and infrastructure modification receives proper security review before implementation.
• Translate complex security requirements (ICD 503, NIST SP 800‑53, NISPOM) into clear, actionable technical guidance that IT deployment teams can execute against, and verify that implementations meet the intent of the requirement.
• Act as the day‑to‑day security liaison embedded with engineering and IT operations, maintaining enough technical depth in systems administration, network architecture, and deployment workflows to evaluate proposed changes on their security merits.
• Provide regular security status roll‑ups to program management and the CSSO that translate technical findings, system vulnerabilities, and deployment risks into program‑level risk language accessible to non‑technical stakeholders.
• Coordinate directly with government security representatives, Authorizing Officials, CSAs, and partner program security teams on all cross‑functional security matters, serving as the primary technical voice from the contractor security organization.
• Communicate system architecture decisions, technical risk posture, and remediation plans to government program security offices with sufficient technical precision to support informed authorization decisions.
• Serve as the Alternate CSSO, assuming full CSSO authority and responsibilities in the primary CSSO’s absence, including independent security decision‑making, incident reporting, and government liaison duties.
• Administer SCI security programs in accordance with ICD 703, ICD 705, ICD 503, NIST SP 800‑53, and applicable NISPOM requirements, ensuring continuous compliance across all program activities.
