PrairieLearn (https://www.prairielearn.com) is an open-source assessment platform originally developed at the University of Illinois and now used by universities across the US (Berkeley, Princeton, Michigan, UIUC, and others). We power mastery-based learning, interactive question generators, and large-scale exams.
We’re a small, profitable, early-stage company (bootstrapped, no VC) and we’re hiring a full-stack engineer to help us continue to grow. You’ll work across the stack and have meaningful ownership from day one.
We’re also developing AI tooling in the product:
* LLM-based agents to help instructors create and test new question generators
* Vision-language models for grading student-submitted work (e.g., math derivations, diagrams, sketches)
This is practical, user-facing AI work with real-world impact — not a research sandbox.
Tech we use:
* Node.js / TypeScript backend, Postgres, AWS, React
* PrairieLearn is open core: https://github.com/PrairieLearn/PrairieLearn
You might be a fit if you:
* Have experience with full-stack web development (TypeScript / Python / SQL / HTML/CSS)
* Enjoy working directly with users (many are instructors and TAs)
* Want to own features end-to-end, from idea to rollout
* Are excited about building practical AI integrations, not just demos
Details:
* Location: Remote (US only)
* Salary: $100k+ depending on experience
* Benefits: Stock options, unlimited PTO, flexible hours
* Role: Full-time. (We’re not able to sponsor visas at this time.)
