Senior Frontend Engineer (Next.js / React)

About LearnWise AI 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. Small team, high ownership, real user impact. Why this role exists 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. What you will do: 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; iterate quickly with design & product. Champion accessibility to WCAG 2.2 AA across components and flows. Own performance: optimize data loading/streaming, reduce bundle size, profile the JS event loop and async flows. Keep dependencies lean and healthy; document decisions; raise the bar through reviews. Deploy, preview, and monitor apps on Vercel (analytics, error tracking

observability). You will do great here if you have: 8+ years building production frontends. Deep Next.js knowledge (App vs Page routes) and strong React + modern TypeScript/JavaScript fundamentals. Mastery of the browser runtime: event loop, promises, concurrency, streaming. Proven track record shipping accessible UI to WCAG 2.2 AA . Professional fluency in English (written & spoken). Bias to action, comfort with ambiguity, and love for startup pace. Nice to have: Built streaming UIs, chat experiences, or AI-powered apps (real-time, RAG, agents). Experience with design systems, motion/interaction details, and component libraries. Tooling for performance & observability (Web Vitals, Lighthouse, bundle analysis). How we work: Default to open: write things down, share context early. Small team, big ownership: you'll own projects end-to-end. Measure > guess: we ship, we instrument, we learn. Quality and speed: we don't choose-we engineer for both. Location : R emote is OK; EU is a must-have. Prefer Barcelona, Spain or Amsterdam, Netherlands if you want hybrid/office. Compensation Salary : competitive (location-adjusted). 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!
