Tech Internships in California

Tech internships in California, listed from company career pages: software, data, hardware, security, product and design roles whose primary location is in California. A posting that names several sites is listed under its first location, and fully remote roles have their own page. California cities with their own page here include Santa Clara, San Francisco and San Jose. The list is checked every 6 hours: new postings show up here soon after they go up, and a role leaves the list once the company takes it down or it is 31 days old. Each Apply button opens the posting on the employer's site.

Open now: 600 for Summer 2027, 49 for Spring 2027, 40 for Winter 2027 and 14 for Fall 2027. A role open to more than one term counts under each.
