Support radiological surveys, contamination control activities, dosimetry oversight, source accountability, and radioactive material handling programs. Participate in development and maintenance of laboratory procedures, technical training materials, and operational guidance documents. Collaborate with multidisciplinary teams to support safe radiological operations, commissioning activities, and operational readiness efforts. Assist with audits, inspections, corrective actions, occurrence investigations, and regulatory interactions related to radiological and laboratory operations. Maintain accurate technical records, laboratory documentation, and radiological program data. Mentor junior technical staff and contribute to development of strong laboratory and radiological safety culture. Support emergency preparedness and response activities associated with radiological operations. Promote continuous improvement initiatives focused on operational excellence, safety, compliance, and technical rigor. Minimum Qualifications Bachelor’s degree in Chemistry, Radiochemistry, Nuclear Engineering, Health Physics, or a related technical discipline. Minimum of 5 years of progressively responsible experience in radiochemistry, radioactive material handling, nuclear laboratory operations, or related radiological environments. Demonstrated knowledge of radiological work practices, contamination controls, laboratory safety, and operational work planning. Experience working with radioactive isotopes, radiochemical separations, analytical instrumentation, and laboratory quality standards. Familiarity with NRC, DOE, Agreement State, or other applicable radiological regulatory frameworks. Strong technical writing, communication, organizational, and problem-solving skills. Ability to work effectively in cross-functional operational and laboratory environments. Bonus Qualifications Advanced degree in Radiochemistry, Chemistry, Nuclear Engineering, Health Physics, or related field. Previous experience supporting or serving in radiation safety program roles. Experience with isotope production, hot cell operations, gloveboxes, or nuclear facility operations. Professional certifications or training related to radiation safety, radiochemistry, or health physics. Experience supporting startup, commissioning, or operational readiness activities in regulated facilities.
