Medical Physicist Jobs in California: Frequently Asked Questions
How do you become a medical physicist in California?
Becoming a medical physicist in California requires a graduate degree in medical physics from a CAMPEP-accredited program, followed by a CAMPEP-accredited residency. California does not issue a state-specific medical physicist license, but most clinical employers require board certification through the American Board of Radiology. Depending on your role, you may also need to register as a radiation use supervisor or authorized medical physicist under the California Department of Public Health's Radiologic Health Branch.
Which companies hire medical physicists in California?
Employers hiring medical physicists in California right now include One Physics, Emfoi, and Providence, based on current listings on Migrate Mate as of October 2026. California's density of NCI-designated cancer centers and large integrated health systems means hiring is spread statewide, with particularly strong activity at academic medical centers in the major metros.
Which California cities have the most medical physicist jobs?
California, Irvine, and San Diego have the most medical physicist openings in California. Los Angeles and San Francisco lead because of their concentration of academic medical centers and comprehensive cancer programs, while San Diego's strong biomedical and research hospital sector drives consistent demand there as well.
Are there remote medical physicist jobs in California?
Yes, but they're rare. Most medical physics work is hands-on and tied to clinical equipment, so fully remote positions are uncommon. About 100% of medical physicist openings tied to California are remote or hybrid as of October 2026, and those positions tend to be in treatment planning review, dosimetric consultation, or physics quality assurance roles that can be performed off-site.
How can I get hired as a medical physicist in California with little or no experience?
The most realistic entry path is a CAMPEP-accredited residency, and California hosts several of the country's most competitive programs at institutions like UCSF, UCLA Health, and Stanford Health Care. New graduates should also look for junior medical physicist or physics assistant roles at large California cancer centers, which sometimes allow candidates to train toward ABR eligibility on the job. A completed graduate degree from a CAMPEP-accredited program and demonstrable clinical rotation experience give applicants a clear edge when competing for these positions.
Where can I find and apply to medical physicist jobs in California?
You can find and apply to medical physicist jobs in California on Migrate Mate, which lists current California openings across hospital systems, cancer centers, and research institutions.
