Descripción

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!
