Radiation Transport and Shielding Engineer Pay Range: $90 - $95.00 per hour Who We Are: TechSource, a Salas O'Brien company, is a nationally recognized engineering and scientific company specializing in the management and technical delivery of large-scale nuclear and high-technology projects with numerous federal agencies, helping to advance missions of national importance for government programs, national laboratories, national security facilities, nuclear operations, and complex projects nationwide. We provide direct access to hundreds of experts and industry leaders in the nuclear sciences, non-proliferation technologies, accelerator physics, and systems engineering arenas with offices in Washington DC, SC, TX, TN, and NM. Our outstanding technical service has earned the company a client retention rate of over 95 percent. As part of Salas O'Brien, we work to attract and retain the best talent because the best talent delivers the best results for our clients. Job Summary: We are hiring a part-time Radiation Transport and Shielding Engineer to provide technical analysis in radiation transport, shielding analysis, and nuclear modeling and simulation. You will work directly with architects, engineers, radiation-protection specialists, clients, and regulatory stakeholders to define data needs, evaluate alternatives, document assumptions and uncertainties, and translate technical results into defensible design recommendations. You may also support other accelerator, nuclear facility, national security, and advanced modeling assignments. This is remote work, with little to no travel. Responsibilities: Support advanced radiation transport, shielding, and dose analyses for accelerator, X-ray, nuclear facility, and other complex radiological applications. Provide practical direction and defensible solutions to unusually complex modeling, shielding, and radiation-protection challenges. Develop conservative bounding analyses when source-term, equipment, operating, or facility information is incomplete, and refine the analysis as design data mature. Construct, execute, review, and document Monte Carlo radiation transport models using MCNP, MCNPX, MCNP6, or comparable tools. Evaluate primary and secondary barriers, roofs, mazes, doors, joints, ducts, cable penetrations, and other streaming paths using facility drawings and equipment information. Qualifications and Experience: US citizenship. PhD in Nuclear Engineering or Physics. Active Q clearance. Demonstrated experience developing, applying, or independently reviewing models using MCNP, MCNPX, MCNP6, or another comparable Monte Carlo radiation transport code. Experience producing or reviewing defensible shielding, dose, or radiation-transport calculations for accelerators, radiation-generating equipment, nuclear facilities, or comparable complex radiological systems. Compensation & Benefits: The expected base pay range for this role is $90 – $95.00 per hour. Actual compensation will be determined based on factors including skills, experience, qualifications, and location.
