Facility Security Officer

Position Summary

We're looking for a proactive, engaged Facility Security Officer to join our headquarters team. This isn't a "check the box" role - we want someone who owns the security program, drives continuous improvement, and brings energy and initiative to everything from audit prep to industry engagement. You'll be the go-to for keeping our programs compliant while also playing an active role in physical security at our HQ facility.

• Administer and maintain facility security clearances and personnel security programs in accordance with the NISPOM and applicable government requirements.

• Serve as the primary liaison with Defense Counterintelligence and Security Agency (DCSA) representatives.

• Prepare for, lead, and actively follow up on security vulnerability assessments (and DCSA audits - including documenting findings, tracking corrective actions, and driving measurable improvement between audit cycles.

• Maintain accurate and up-to-date records in DISS, NISS, and other required systems.

Physical Security

• Oversee HQ physical security posture including access control, visitor management, and classified space requirements.

• Identify gaps and make recommendations for improvements proactively - not reactively.

Continuous Improvement and Industry Engagement

• Actively participate in the security professional community - NCMS, ISAC chapters, ASIS, industry working groups, DSS outreach events, and relevant conferences.

• Bring back actionable intelligence and best practices to the team.

• Stay current on policy changes, emerging threats, and industry trends, and translate those into updates to our internal program.

Team and Culture

• Collaborate cross-functionally with Program Managers, Contracts, HR, and IT.

• Maintain a positive, solutions oriented presence on the team.

• Support and mentor junior security staff as the team grows.

Requirements

• 3-5+ years of FSO or industrial security experience in a defense contractor environment.

• Active Secret or Top Secret clearance.

• Strong working knowledge of the NISPOM, DISS, NISS, and DCSA processes.

• Demonstrated track record of audit readiness, not just passing audits, but actively improving scores and correcting findings between cycles.

• Someone who is plugged into the security community, attends events, knows their DCSA reps by name, and brings that knowledge back to the organization.

• Excellent communication and interpersonal skills, you'll be working with everyone from program staff to senior leadership.

• Self-starter who doesn't need to be told what needs attention.

Preferred

• FSO Program Management for Possessing Facilities certification (CDSE).

• Active TS with SCI eligibility.

• NCMS membership or similar professional affiliation.

• Experience supporting multiple facility clearances or a multi-site environment.

Special Note

Corporate FSO - What the Role Actually Looks Like

A practical guide to the day-to-day, month-to-month reality of the FSO role

Daily

• Check DISS/NISS for pending actions - incoming visit requests, investigation updates, clearance flags.

• Respond to questions from program staff (access decisions, visitor management, classified space questions).

• Handle any incidents or anomalies from the previous day.

• Touch base with DCSA rep if anything is active.

• Review access logs, badging reports, or any physical security flags at HQ.

Weekly

• Meet with program managers to stay ahead of upcoming contract requirements, new hires needing clearances, or travel to classified locations.

• Review your audit improvement tracker - what did DCSA flag last time, what has been fixed, what is still open?

• Team check-ins if managing other security staff.

• Scan CDSE updates, DSS advisories, or NCMS newsletters for anything relevant.

Monthly

• Pull together a security metrics snapshot for leadership (clearance status, open actions, audit readiness posture).

• Run or coordinate security awareness training for staff.

• Attend a local NCMS chapter meeting, DCSA industry day, or similar event - and produce a brief summary of key takeaways for the team.

• Review and update Standard Practice Procedures (SPPs) if anything has changed.

Quarterly / Annually

• Lead internal mock audits or self-inspections so there are zero surprises when DCSA arrives.

• Attend a larger conference - NCMS National Seminar, ASIS GSX, or similar - and bring back a briefing for the team.

• Update the corrective action plan based on the last audit and track measurable progress toward a better score.

• Brief leadership on the state of the security program, current risks, and upcoming requirements.

The Community Piece

A great FSO is genuinely connected to the broader security community. That means:

• They know their DCSA Industrial Security Representative personally - not just as an auditor who shows up once a year.

• They are active in NCMS (the professional association for cleared contractors) - attending local chapter events, networking with FSOs at peer companies, and occasionally presenting.

• They follow CDSE training updates and voluntarily pursue new certifications.

• When a policy changes (like a NISPOM revision), they already knew it was coming.
