Software Engineer, Full-Stack 

From Primer’s posting

Primer's goal is simple: fix K–12 education in America. We build schools from the ground up — and we run them on something nobody's built before: a single operating system for the entire school. We call it PrimerOS. It covers real estate, teacher experience, parent experience, the most advanced academic program in the world, our back-office operating stack, and much more. We're looking for exceptional, multidisciplinary engineers to help build it. You'll redesign the school experience around modern technology and ship features that teachers, students, families, and state teams rely on every day.
