RSI seeks a highly experienced Subject Matter Expert (SME) in Remote Sensing and Nuclear Activity Detection located in Washington, DC.to support program reviews and conferences on mission‑critical efforts to prevent, detect, and deter nuclear proliferation worldwide. This SME will lead assigned technical analysis, program and conference reviews, and operational advisement for detecting nuclear‑related activities from stand‑off ranges greater than 100 meters from a facility, including airborne, orbital, deep‑space, and planetary‑based sensing platforms.

The role requires technical expertise in nuclear signatures-radiological, spectral, thermal, seismic, neutron, gamma, and other modalities‑and the integration of remote systems capable of identifying, characterizing, and assessing nuclear‑related operations

• Serve as the primary technical authority/SME on remote detection of nuclear materials, activities, and facilities, including from airborne, satellite, and extraterrestrial platforms.
• Understand the technology behind analyzing nuclear, radiological, and associated signatures detectable at long ranges, including optical, infrared, multispectral/hyperspectral, RF, gamma/neutron, and charged‑particle detection pathways.
• Understand and interpret models for nuclear activity indicators such as:
• Uranium enrichment operations
• Reprocessing signatures
• Reactor operations
• Radiological source movement
• Nuclear testing or subcritical experiments
• Participate in assigned Program Reviews and Conferences pertinent to your Areaof expertise regarding remote sensing.

• Provide technical guidance for advanced sensor systems, including:
• Satellite payloads
• High‑altitude platforms (balloons, UAVs)
• Ground‑based long‑range detection arrays
• Deep‑space or planetary remote‑sensing systems
• Evaluate emerging technologies (AI/ML‑based detection, quantum sensors, advanced spectroscopy, wide‑area persistent surveillance).
• Support R&D programs across government, laboratory, academic, and industry partners.

• Produce intelligence‑quality assessments on foreign nuclear programs using remote sensing data as assigned
• Advise leadership on the threat environment, system vulnerabilities, and technology gaps.
• Support the development of national strategies and policies for nuclear non‑proliferation monitoring and verification.

• Coordinate with interagency partners, national laboratories, the intelligence community, defense agencies, internal program office team members and international entities, as assigned.
• Present complex technical findings to diverse audiences, including senior government officials.
• Develop technical briefings, white papers, risk assessments, and program review reports.

• Advanced degree (M.S. or Ph.D. preferred) in Nuclear Engineering, Physics, Remote Sensing, Radiological…
