You'll design the surfaces where learning actually happens. Learn mode chat, hint ladder, explain-back flow, recall queue. Ship in code alongside engineering.
No formal cover letter. Send a résumé + a paragraph on why the “refuse to give the answer” stance appeals to you.
You'll own the Brainback web app end-to-end — from the Learn mode chat UX to the recall queue to the parent dashboard. Next.js 15, React 19, Tailwind, TypeScript. Deep taste required.
You'll own the model orchestration layer — routing between Sonnet and Haiku, prompt caching, streaming, output guard. Deep familiarity with LLM APIs required.
You'll bring rigorous learning-science thinking into the product. Design experiments, review the literature, shape the pedagogical stance, and write.
You'll own the visual identity — typography, illustration, motion, the Brainback book. Editorial sensibility required.
