2027 Software Engineering (SWE) Internships in Pennsylvania

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 Pennsylvania. 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. Pennsylvania internships cluster in Philadelphia and Pittsburgh, with more in the Lehigh Valley and around Harrisburg. Philadelphia is strong in pharmaceuticals, health care and insurance, while Pittsburgh is known for robotics, autonomous vehicles, advanced manufacturing and university research.

Open now: 10 for Summer 2027. Top companies: Lockheed Martin (3), General Dynamics Mission Systems (2) and Smith Meter Inc (2).
