Job description

Who We Are: Our team is helping ensure the safety of nuclear power and the nuclear fuel cycle at a time when the country and world are considering increasing nuclear power’s role in meeting energy needs. Objectives of this Role: For the U.S. Nuclear Regulatory Commission (NRC) and other clients, perform technical and regulatory evaluations for ensuring the safety of nuclear facilities, nuclear materials processing and management, and radioactive waste disposal.

Conduct independent engineering calculations and modeling to support worker and public radiological safety evaluations under normal and accident conditions. Apply your nuclear engineering expertise to support analyses of nuclear regulatory frameworks and guidance documents. Contribute to preparation of proposals and support other business development activities applicable to your technical expertise and responsibility.

Daily and Monthly Responsibilities: Using your engineering knowledge of nuclear systems, evaluate and quantify hazards, consequences, and risks from external and internal exposure to radiation from, for example, radioactive materials in storage and transportation packaging or in air, water, and soil. Conduct both qualitative and quantitative engineering safety assessments of nuclear fuel cycle activities, including using simple tools like spreadsheet or Python calculations, or specialized modeling software. Support nuclear licensing reviews.

Evaluate regulations and guidance for their applicability to new and advanced nuclear technologies. Contribute to written technical reports and regulatory documents and communicate technical concepts clearly with clients and colleagues. Requirements: Requires a Bachelors, Masters or a PhD in Nuclear Engineering, Environmental Engineering, or related Engineering degree fields with sufficient experience in nuclear or radiological safety.

Those with graduate degrees may require less years of experience. 3 years: Experience applying understanding of nuclear engineering concepts and their regulatory context is required. Experience conducting engineering assessments of the nuclear power fuel cycle or radioactive materials is preferred.

Experience with applicable nuclear engineering codes (e.g. for transport, shielding, criticality, and dose) or pathway dose codes is desired. Excellent speaking and writing skills and the ability to work independently and in multi-disciplinary teams are required.

Due to the nature of the contract, candidates must have US Citizenship or have held US Permanent Residency (non-U.S. citizen national, lawful permanent resident, asylee, or refugee) for at least 5 years. A valid/clear driver's license is required.
