Mechanical Engineer Jobs in California: Frequently Asked Questions
How do you become a mechanical engineer in California?
Becoming a mechanical engineer in California starts with a bachelor's degree in mechanical engineering from an ABET-accredited program, which most California employers require at minimum. For roles in public infrastructure, consulting, or any position requiring stamped drawings, you pursue licensure through the California Board for Professional Engineers, Land Surveyors, and Geologists by passing the Fundamentals of Engineering exam and later the Principles and Practice of Engineering exam after gaining qualifying experience.
How much do mechanical engineers make in California?
Mechanical engineers in California earn a median of about $130,900 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $82,070 for the lowest 10% to over $203,620 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire mechanical engineers in California?
Employers hiring mechanical engineers in California right now include Tesla, Anduril, and KLA, based on current listings on Migrate Mate as of November 2026. California's concentration of aerospace primes, semiconductor manufacturers, and medical device companies means demand stays broad across industry sectors rather than clustering around a single employer type.
Which California cities have the most mechanical engineer jobs?
San Francisco, Fremont, and San Jose have the most mechanical engineer openings in California right now. The distribution reflects the state's major industry clusters: the Los Angeles area draws heavily from aerospace and defense contractors, the Bay Area is driven by semiconductor, hardware, and clean-tech firms, and San Diego is anchored by defense systems and biomedical engineering employers.
Are there remote mechanical engineer jobs in California?
Yes, but they're rare. Most mechanical engineering work is hands-on and tied to labs, test facilities, or manufacturing floors, which limits full remote arrangements. About 32% of mechanical engineer openings tied to California are remote or hybrid as of November 2026, and those tend to favor design review, simulation, and systems analysis tasks rather than prototype or production roles.
How can I get hired as a mechanical engineer in California with little or no experience?
The most realistic entry path is through an internship or new-graduate rotational program, which major California aerospace and technology employers run specifically for candidates without full-time experience. Companies like Northrop Grumman and Applied Materials recruit from California's engineering programs into structured early-career roles. A portfolio of senior capstone or project work, along with an Engineer-in-Training designation from the California Board, signals readiness and gives candidates a concrete edge in competitive entry-level applicant pools.
Where can I find and apply to mechanical engineer jobs in California?
