Descripción del empleo

Overview

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 frontend engineer who can take product ideas from Figma to fast, accessible production apps on Vercel and lead the craft on performance and accessibility.

Responsibilities

• Translate Figma designs into responsive, accessible UI; own performance by optimizing data loading/streaming, reducing bundle size, and profiling the JS event loop and async flows.
• Ship high-quality frontend apps in Next.js, React, and TypeScript (App Router & Page Router, SSR/SSG/ISR, middleware, edge patterns).
• Deploy, preview, and monitor apps on Vercel (analytics, error tracking, observability).
• You’ll own projects end-to-end in a small team with big ownership.
• Balance quality and speed; the team engineers for both rather than choosing one over the other.

Qualifications

• 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).
• Experience building streaming UIs, chat experiences, or AI-powered apps (real-time, RAG, agents).
• Tooling for performance & observability (Web Vitals, Lighthouse, bundle analysis).
• Prefer Barcelona, Spain or Amsterdam, Netherlands if you want hybrid / office.

Benefits

Flexible time off, home-office budget, and learning stipend.
