Regular on-site support at Quantico is required, with limited hybrid flexibility based on customer requirements and mission needs.

Key Responsibilities

• Provide senior-level counterintelligence subject matter expertise in direct support of MDCO and its mission partners.
• Plan and support CI activities associated with Research, Development, and Acquisition protection.
• Identify and assess foreign intelligence entity threats, vulnerabilities, and risks affecting sensitive technologies, programs, personnel, facilities, and activities.

• Support the development, evaluation, and implementation of CI Support Plans and related program protection activities.
• Apply investigative and operational CI experience to ongoing customer requirements and emerging threats.
• Support the identification and protection of Critical Program Information (CPI) and other sensitive technologies and capabilities, as applicable to customer requirements.
• Research and analyze threat information and other relevant data to develop actionable findings, assessments, and recommendations.
• Engage directly with senior government personnel to communicate ongoing activities, threats, findings, risks, and recommended courses of action.
• Prepare and deliver briefings, assessments, reports, and other products for government stakeholders.
• Coordinate and collaborate with CI agents, analysts, acquisition and program personnel, security professionals, and other mission partners.
• Adapt to changing operational priorities, schedules, and customer requirements while operating with a high degree of independence.

Required Qualifications

• Current Top Secret (TS) security clearance with SCI eligibility.
• 10+ years of professional counterintelligence experience supporting investigations, operations, or a combination of both.
• 5+ years of experience supporting Research, Development, and Acquisition protection or closely related CI protection activities.
• Demonstrated knowledge of counterintelligence principles, investigative or operational tradecraft, threat identification, and risk assessment.
• Demonstrated ability to independently assess complex information and provide well-supported recommendations.
• Experience developing and presenting briefings, assessments, recommendations, or other products to government stakeholders.
• Strong written and verbal communication skills.
• Ability to work effectively in a customer-facing role and engage professionally with personnel at varying levels of seniority.
• Ability to provide on-site support at Quantico, Virginia, as required by the customer.

Preferred Qualifications

• Previous experience as an MDCO Agent or Analyst, particularly in a supervisory or leadership capacity.
• Prior supervisory experience within a counterintelligence, investigative, operational, or analytic organization.
• Experience developing or executing CI Support Plans or CI Coverage Plans.
• Experience conducting CI risk assessments, vulnerability assessments, or threat assessments supporting RDA or program protection.
• Knowledge of Critical Program Information (CPI), Supply Chain Risk Management (SCRM), or related technology and program protection activities.
• Familiarity with applicable DoD CI and RDA/program protection policies and frameworks.
• Extensive experience supporting DoD, Intelligence Community (IC), MDCO, or related national security missions.
• Demonstrated experience advising or briefing senior government leaders and decision-makers.
• Ability to support the customer routinely on-site at Quantico, with familiarity with the Washington, D.C., Maryland, and Virginia region.
• Demonstrated ability to operate effectively with variable schedules and changing mission requirements.

What Success Looks Like

Success in this role requires establishing credibility and trust with the customer, applying substantial CI experience to complex RDA protection challenges, and operating effectively with limited oversight. The SME must move comfortably between research and analysis, operational discussions, senior-level engagement, and actionable recommendations while adapting to evolving priorities.

The SME will represent 3GIMBALS professionally in a highly visible customer-facing role and provide expertise that complements the broader multidisciplinary team.
