Flexible Work, Better Balance
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.
