Job Summary:

As a full-time Remote Sensing & Nuclear Activity Detection Engineer, you will support program reviews and conferences on mission-critical efforts to prevent, detect, and deter nuclear proliferation worldwide. You will conduct technical analysis, perform program and conference reviews, and advise on 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, using your 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. This is a full-time, onsite role supporting Department of Energy/National Nuclear Security Administration (DOE/NNSA), located in Washington, DC.

Qualifications and Experience:

• Active Q or Top Secret clearance.
• 20 or more years of direct nuclear detection, remote sensing, or non-proliferation work experience. DOE SRS tritium operations work experience.
• Bachelor’s degree in an engineering discipline.

• Deep knowledge of nuclear signatures and relevant sensing modalities (e.g., gamma/neutron detection, hyperspectral imaging, thermal infrared analysis, RF anomaly detection).
• Understanding of satellite or airborne sensing systems, or high‑altitude/space-based detection platforms.
• Strong modeling, analysis, and technical writing skills.
• Willingness to assist the program team with any task assigned, ranging from hanging posters at program reviews/conferences to taking meeting minutes in assigned mission critical meetings as well as performing your own work scope on complex-wide program proposals reviews and assessments.

Preferred qualifications:

• Master’s or PhD in nuclear engineering, physics, remote sensing, radiological science, space systems engineering, or related field.

• Experience working with DOE/NNSA, DoD, NASA, or the Intelligence Community.
• Familiarity with nuclear fuel cycle processes, facility operations, and proliferation pathways.
• Hands‑on experience with:
• Synthetic aperture radar (SAR)
• Hyperspectral/multispectral payloads
• Radiation detection instrumentation
• AI/ML anomaly detection for overhead imagery or sensor data
• Knowledge of orbital mechanics, space mission design, or planetary remote sensing.

Compensation & Benefits:

The expected base salary range for this role is $185 – $195,000 annually. Actual compensation will be determined based on factors including skills, experience, qualifications, and location.
