Full-Stack Software Engineer

Are you passionate about building innovative web applications and using AI to address real-world learning challenges? Do you want to help shape the future of education?
PrairieLearn is an early-stage EdTech startup. We are hiring talented Full-Stack Software Engineers.

Location: Fully remote (anywhere in the US)
Position Type: Full-time
Visa Sponsorship: Unfortunately, we cannot sponsor visas at this time.

PrairieLearn is an open-source assessment platform, originally developed at the University of Illinois and now used at top universities across the US, including Berkeley, Princeton, Michigan, and UIUC. We empower mastery-based learning and large-scale assessment with an emphasis on reliability and innovation. We are like a "power-user" version of Gradescope/Canvas/Moodle. We’re also developing AI tooling in the product, including LLM agents to help instructors create content, and vision-language models to help grade student work. This is practical, user-facing AI work with real-world impact — not a research sandbox.

We are a small, profitable, open-source, bootstrapped company growing quickly. Our users love us and we have very high retention and rapid spread through word of mouth. As an early-stage hire, you’ll work across the stack and enjoy meaningful ownership from day one. You’ll help deliver practical, user-facing features with clear guardrails and authentic educational impact.
