Senior Frontend Engineer (Next. Js / React)

Overview

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.

Responsibilities

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).

Qualifications

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

Remote 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.
