We are seeking a CBRN Subject Matter Expert (SME) to support to support risk assessment efforts in support of the Department of Homeland Security (DHS). The primary place of performance will be at SPA Headquarters in Alexandria, VA with regular visits to customer sites in VA and DC.

The CBRN SME provides specialized technical expertise on CBRN/WMD risk and counterterrorism to support an Operations Research (OR) team developing models, simulations, and risk assessment tools. The role advises OR analysts on threat pathways, agent characteristics, detection and response capabilities, operational concepts, and consequence mechanisms to ensure analytic approaches and assumptions are technically valid and operationally realistic. Focus areas include program- and jurisdictional-level CBRN risk and capability analysis, use of DHS risk models and related frameworks, and technical input to decision support for CWMD prevention, detection, and response programs. Works closely with the OR team to design model structures, define scenarios, select and parameterize inputs, and interpret outputs for leadership and stakeholders. Responsibilities include subject-matter review of modeling, simulation, analysis, and visualization products; contributions to technical analyses, requirements, concepts of operation, and test documentation; and support to Verification, Validation, and Accreditation (VV&A) activities. Participates in, and when needed, leads technical portions of integrated product teams and working groups, and helps develop and review risk and gap assessment reports, a generalized jurisdictional assessment approach, monthly progress reports, and technical briefings that present key CBRN findings and recommendations to CWMD and CBP leadership.

Required:

• Master's degree with 10+ years of experience.
• Demonstrated subject-matter expertise in CBRNE/WMD, including one or more of the following: chemical, biological, radiological, nuclear, and/or explosive threats; CBRN defense capabilities; CBRN detection and surveillance systems; and CBRN incident response and consequence management.
• Experience working with or supporting analytic/modeling efforts (e.g., operations research, risk assessment, modeling and simulation, or systems analysis), providing technical/domain input to model design, assumptions, and interpretation of results.
• Demonstrated experience in homeland security, defense, or related complex mission areas involving CBRN risk, terrorism, or counterproliferation, including program-level and/or jurisdictional-level assessments.
• Proven ability to communicate complex CBRN technical concepts clearly, both in written and verbal formats, to diverse stakeholders including OR analysts, senior government leaders, technical experts, and state and local partners.
• Active Secret clearance with ability to obtain DHS Suitability.
• Able to work fully onsite based on client needs.

Desired:

• Experience providing technical CBRN support to: program planning and oversight; exercise development, execution, and evaluation; system-level analysis; and system integration, including understanding of CBRN threats, vulnerabilities, and layered defense architectures.
• Familiarity with DHS risk models, CBRN models, and CBRN detection architecture concepts, and prior experience integrating these into analytic or OR tools.
• Active Top Secret clearance and/or active DHS Suitability.
