2027 Summer Tech Internships in California

Tech internships for the Summer 2027 term whose primary location is in California. Fully remote roles aren't tied to a state, so they aren't listed here. Tech here means 13 fields: Software Engineering, Data Science & Machine Learning, Data Analytics, Systems Engineering, Cyber Security, IT & Technical Support, Hardware & Embedded Engineering, DevOps & Infrastructure, Robotics & Controls, Simulation, Game Design, Quantitative Finance and UI/UX Design. Postings that don't name a term are listed under Summer, since most internships run over the summer. 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.

By field: 158 in Data Science & Machine Learning, 158 in Hardware & Embedded Engineering, 129 in Software Engineering and 23 in Systems Engineering. Top companies: NVIDIA (33), Waymo (31) and The Aerospace Corporation (21).
