2027 Software Engineering (SWE) Internships in California

Software Engineering internships for every term that starts in 2027: summer internships and fall, winter and spring co-ops, each counted once whose primary location is in California. Fully remote roles aren't tied to a state, so they aren't listed here. Roles posted as SWE, software developer or SDE internships are listed here too. Every listing comes from a company career page, and the list is checked every 6 hours: a role leaves it once the company takes the posting down or it is 31 days old. Each Apply button opens the posting on the employer's site. California holds the most internship listings of any state, concentrated in the San Francisco Bay Area and Silicon Valley, Los Angeles and Orange County, and San Diego. The Bay Area leans toward software, hardware and venture-backed startups, Los Angeles toward entertainment, media and aerospace, and San Diego toward biotechnology, defense and wireless technology.

Open now: 129 for Summer 2027, 12 for Spring 2027 and 9 for Winter 2027. Top companies: Cisco (6), NVIDIA (5) and Revel (5).
