Work from home frontend developer

We're an AI-first scale up helping universities and colleges support students and faculty with smart, knowledge-driven tools from AI tutoring to feedback and support. We need a senior who can take product ideas from Figma to fast, accessible, production apps on Vercel - and lead the craft on performance, and accessibility. Ship high-quality frontend apps in Next.js, React and TypeScript (App Router & Page Router, SSR/SSG/ISR, middleware, edge patterns). Translate Figma designs into responsive, accessible UI; Own performance: optimize data loading/streaming, reduce bundle size, profile the JS event loop and async flows. Deploy, preview, and monitor apps on Vercel (analytics, error tracking, observability). 8+ years building production frontends. ~ Deep Next.js knowledge (App vs Page routes) and strong React + modern TypeScript/JavaScript fundamentals. ~ Professional fluency in English (written & spoken). ~ Built streaming UIs, chat experiences, or AI-powered apps (real-time, RAG

agents). Tooling for performance & observability (Web Vitals, Lighthouse, bundle analysis). Small team, big ownership: you'll own projects end-to-end. Quality and speed: we don't choose-we engineer for both. Prefer Barcelona, Spain or Amsterdam, Netherlands if you want hybrid/office. Flexible time off, home-office budget, and learning stipend. If you are passionate about creating intuitive, engaging user interfaces, interested in working for a startup, and excited about the opportunity to work on innovative AI projects that make an impact for students just like you, we would love to hear from you!
