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!
