Business Development Assistant Jobs in California: Frequently Asked Questions

How do you become a business development assistant in California?

Business development assistants in California do not require a state-issued license, but employers consistently expect a bachelor's degree in business, marketing, or communications. Most candidates build their foundation through internships or entry-level roles in sales coordination or account management. California's large technology and professional services sectors are the most common entry points, and completing coursework or certifications in CRM tools and data analysis gives applicants a meaningful edge in a competitive market.

Which companies hire business development assistants in California?

Employers hiring business development assistants in California right now include WSP in the U.S., BKF Engineers, and CBRE, based on current listings on Migrate Mate as of June 2026. California's concentration of technology headquarters, healthcare systems, and media companies makes it one of the most active states for this role year-round.

Which California cities have the most business development assistant jobs?

San Francisco, Los Angeles, and San Diego have the most business development assistant openings in California. The distribution reflects where California's largest corporate headquarters and regional offices are clustered, with Los Angeles driven by entertainment and media, San Francisco and its surrounding Bay Area by technology and venture-backed firms, and San Diego by a robust life sciences and defense contracting sector.

Are there remote business development assistant jobs in California?

Yes, and they're more common than in many other fields, since business development assistants handle relationship management, CRM work, and research that translate well to remote settings. About 28% of business development assistant openings tied to California are remote or hybrid as of June 2026, reflecting broader trends in California's technology and professional services sectors. Pipeline research, proposal preparation, and outreach coordination are the tasks most frequently performed remotely.

How can I get hired as a business development assistant in California with little or no experience?

The most realistic entry path is a sales coordinator or marketing assistant role at a California technology company or staffing firm, where you build CRM and client communication skills before stepping into a dedicated business development title. Large California employers in life sciences and enterprise software regularly hire new graduates into rotational or associate programs that expose candidates to business development functions. Building a portfolio of market research samples and earning a recognized CRM certification significantly strengthens applications for candidates without direct experience.
