Mechanical Design Engineer Jobs in California: Frequently Asked Questions
How do you become a mechanical design engineer in California?
Most California employers require at least a bachelor's degree in mechanical engineering or a closely related field from an ABET-accredited program. For roles in regulated industries like defense, medical devices, or public infrastructure, many engineers pursue licensure through the California Board for Professional Engineers, Land Surveyors, and Geologists, starting with the Fundamentals of Engineering exam and progressing to the Professional Engineer credential after gaining qualifying experience.
How much do mechanical design engineers make in California?
Mechanical design 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 design engineers in California?
Employers hiring mechanical design engineers in California right now include Apple, Rivian, and Cadence Design Systems, based on current listings on Migrate Mate as of June 2026. California's dense concentration of aerospace primes, semiconductor firms, and medical device companies means sustained demand across a wide range of employer sizes and industries.
Which California cities have the most mechanical design engineer jobs?
The cities with the most mechanical design engineer openings in California are Cupertino, San Jose, and Sunnyvale. The Los Angeles area anchors demand through its aerospace and defense base, the Bay Area through hardware and robotics companies tied to the tech industry, and San Diego through its medical device and defense contractor ecosystem.
Are there remote mechanical design engineer jobs in California?
Yes, but they're rare. Mechanical design engineering is fundamentally hands-on, requiring access to labs, prototypes, and manufacturing floors, so most roles are on-site or hybrid at best. About 11% of mechanical design engineer openings tied to California are remote or hybrid as of June 2026, and those tend to concentrate in early-stage design review, simulation, and documentation work rather than full-cycle product development.
How can I get hired as a mechanical design engineer in California with little or no experience?
The most realistic entry path is a new-graduate engineering role or a co-op converted to full-time at a large California manufacturer. Companies like Lockheed Martin, Boston Scientific, and Applied Materials run structured new-grad programs at their California facilities. Building a portfolio of CAD models and a senior capstone project strengthens applications, and a passed Fundamentals of Engineering exam signals seriousness to California hiring managers even before you accumulate years of work experience.
Where can I find and apply to mechanical design engineer jobs in California?
