83 more open roles across 52 firms are on Jorb AI.
52 firms are open for software engineering internships in London right now, each with its own portal, documents and deadline, and 4 more firms are due to open this season. Jorb AI's application agent handles the multi-firm workload in one place, tailoring a CV and cover letter for each role you pursue and tracking each application alongside the rest.
“Opened” is the date the firm posted a role, or the day Jorb AI first saw it on the firm’s own careers site, which we check daily. “No longer listed” means the posting has been gone for a few days. Last season’s dates are shown only for firms we were already following when that season began.
Open counts every listing still open, including those first seen before 1 June; Opened this season counts only those first seen since.
