AI-native learning for every school. Backed by Y Combinator.
About the role
Get acquainted with the React/TypeScript app, the Supabase backend, the content pipeline, and the agent fleets that feed it. Take ownership of your first fleet — write the spec, build the harness, set the QA gate — and start shipping through it. Design the roadmap with me: ~50% shipping product across the stack, ~25% building and running agent infrastructure, ~25% talking to teachers, students, and districts — and turning what you hear into the roadmap.
What they're looking for
- Has 5+ years shipping products that real end users touch daily, and has opinions about what makes them good
- Is high-agency: can take ambiguous feedback and turn it into shipped product without waiting for a spec
- Is expert-level with AI coding tools and uses them to move dramatically faster — without outsourcing judgment to them
- Gets excited, not exhausted, by the idea of managing a dozen concurrent agents
- Wants tight feedback loops with real users (some of whom are eleven)
- Has high schlep tolerance — roster CSV imports, school-device performance quirks, and school-specific customization are part of the job and part of why we win
More about this role
Bloomy is an AI tutor and curriculum for K-12 students. Our student users are learning approximately 2x faster in early pilots, and students and teachers alike love our product.
How it works: We diagnose students’ skill gaps, map out a personalized learning path for them, and then have an AI tutor teach them. The AI learns about how they learn, so it can increase the efficiency of its teaching and, consequently, their learning.
How you can help: You will be joining as the founding engineer. Right now, engineering is one founder (me) orchestrating fleets of coding agents that produce a large share of our code and curriculum against specs, verification harnesses, and QA gates. I’m a solo founder with domain expertise as a former teacher and sales leader, but I’m not an engineer by training, and I need someone with true technical expertise to actualize the vision of improving education for millions of students.
Why we’re different: Bloomy is AI-native. I built the entire product from February to April of this year, got it into the hands of 500 students across 6 schools from April to June, started YC in June, and have roughly doubled ARR every 2 weeks since then. Thousands of students...
