About The Position

Health Physicist About Us Are you ready to be part of a team that is bringing revolutionary technology to the remediation industries? DISA Technologies is revolutionizing mineral recovery with our patented High-Pressure Slurry Ablation (HPSA) technology—an innovative solution that upgrades critical minerals from mined ore and legacy waste. Serving both the mining and remediation sectors, we recover valuable resources that power industry, strengthen energy independence, and restore contaminated sites to productive use. Our technology unlocks economic and environmental value, transforming how the world processes, remediates, and recycles essential mineral assets. Job Summary The Health Physicist is responsible for developing, implementing, and maintaining DISA’s radiation protection programs that protect workers, the public, and the environment from unnecessary exposure to ionizing radiation. This position requires a proficient practitioner with at least 10 years of hands-on experience in radiological surveys, exposure assessment, contamination control, dosimetry, radioactive material handling, regulatory compliance, and field implementation of ALARA principles. The successful candidate will provide technical leadership to DISA’s operations, and management teams; evaluate radiological hazards; prepare and review procedures; support licensing and regulatory commitments; and ensure that radiological work is conducted safely, efficiently, and in compliance with applicable federal, state, and site-specific requirements.
