Health PhysicistValar Atomics
We are looking for a Health Physicist to serve as the technical backbone of our Radiation Protection Program. You will be the subject matter expert responsible for the "why" and "how" of radiological safety-from calculating shielding requirements to designing the dosimetry program.
This role begins with an onboarding period at our HQ in Los Angeles before deploying to our pilot site in Utah. You will work closely with the Principal Health Physicist and the Operations team to ensure our program is robust, defensible, and built for the real world.
What You’ll Do
Technical Authority: Develop and maintain the technical basis for the Radiation Protection Program, including internal/external dosimetry, instrumentation, and airborne radioactivity monitoring.
ALARA Planning: Lead ALARA reviews for high-hazard work. Perform shielding calculations and dose assessments to engineer safety into every job.
Procedure Development: Write clear, concise technical procedures that translate regulatory requirements (10 CFR 835) into actionable steps for the field team.
Instrumentation: Oversee the selection, calibration, and maintenance of our radiological instrumentation fleet, ensuring our data is always accurate.
Training: Develop and deliver high-impact radiation safety training to staff, from General Employees to Radiological Workers.
Regulatory Compliance: Manage the reporting and recordkeeping requirements, ensuring we are always audit-ready and fully compliant with DOE and state regulations.
Who You Are
A Problem Solver: You don't just identify a high dose rate; you find the engineering solution to lower it.
A Communicator: You can explain complex radiological concepts to engineers, operators, and regulators with equal clarity.
Detail-Oriented: You know that in Health Physics, accuracy is everything. You take pride in precise calculations and flawless documentation.
Driven: You are excited to build a program from the ground up in a fast-paced startup environment.
