Laboratory Jobs in California: Frequently Asked Questions
How do you become a laboratory in California?
The path depends on the type of laboratory work you pursue. For clinical laboratory roles, California requires a Clinical Laboratory Scientist license issued by the California Department of Public Health, which requires a bachelor's degree in a biological or chemical science plus a supervised training program and passing the required exam. Research and industrial lab positions typically require at minimum a bachelor's degree in a relevant science, with no state license required but relevant certifications strengthening candidacy.
Which companies hire laboratorys in California?
Employers hiring laboratorys in California right now include Kaiser Permanente, University of Southern California, and Emanate Health, based on current listings on Migrate Mate as of August 2026. California's deep biotechnology and pharmaceutical industry means many of these employers are concentrated in San Diego's Torrey Pines corridor, the Bay Area, and the greater Los Angeles area.
Which California cities have the most laboratory jobs?
Los Angeles, Irvine, and San Diego lead California in laboratory job openings. San Diego and the Bay Area drive the concentration through their established biotech and pharmaceutical clusters, while Los Angeles adds volume through its large hospital networks, environmental testing firms, and university research institutions that generate consistent hiring across specialties.
Are there remote laboratory jobs in California?
Yes, but they're rare. Most laboratory work requires hands-on instrument use, sample handling, or regulated facility access that cannot be done remotely. About 9% of laboratory openings tied to California are remote or hybrid as of August 2026, and those positions tend to be in data analysis, bioinformatics, regulatory affairs, or laboratory management rather than bench science.
How can I get hired as a laboratory in California with little or no experience?
The most realistic entry point is applying for a laboratory assistant or lab technician role, which typically requires only an associate's or bachelor's degree and no prior work history. Large California health systems such as Dignity Health and UCLA Health run new-graduate programs and phlebotomy-to-CLS training pathways. Completing a California CDPH-approved clinical training program while enrolled strengthens any application significantly, and moving laterally from a related role such as a pharmacy technician or specimen processor is a well-worn path into the field.
Where can I find and apply to laboratory jobs in California?
You can find and apply to laboratory jobs in California on Migrate Mate, which lists current openings from employers hiring in the state right now. Search the listings, find roles that match your background and target location, and apply directly to the ones that fit.
