Spring/Summer 2027 Engineering Intern 

From Primer’s posting

We're hiring Full Stack Software Engineering Interns. The internship begins in January, May, or June, with a preferred commitment of 4 to 8 months. You'll build PrimerOS, the operating system that runs our schools, shipping features that teachers, students, and families rely on every day. Primer's goal is simple: fix K–12 education in America. We build schools from the ground up and run them on a single operating system nobody's built before. That means the work is broad by nature. Our engineering projects span frontend, backend, systems, hardware, and more. As a startup, we give interns real ownership and mission-critical work, with a small, high-performing team around you for mentorship and support. WHAT YOU'LL DO
