Our client, is a global leader in the development, integration, and implementation of advanced physical and cybersecurity, intelligence, and IT solutions, delivering complete end-to-end solutions on the enterprise and national levels. They are now looking for an experienced Frontend Developer — UX/UI-First (Designer Developer).

Location: Europe
Type: Remote, Full-time
Start date: ASAP
About the Role:

This role requires a highly experienced UX/UI-first frontend developer — ideally someone who started as a UX/UI designer and moved into development. You care deeply about usability and polish, and you can take a flow from concept design production UI quickly. You'll use Cursor to implement and iterate your own designs efficiently.

Responsibilities:

• Own the UI/UX for key product areas: dashboards, learning flows, content editors, assessments, analytics, and AI-driven experiences.
• Design and implement interfaces in React, using React Query for data fetching/caching and app state synchronization.
• Use Cursor as a core part of your workflow to translate designs into clean, scalable components quickly.
• Build and maintain a consistent component system (reusable patterns, UI states, accessibility, responsiveness).
• Collaborate with backend to integrate APIs with great UX (loading/error states, optimistic updates, graceful edge cases).
• Continuously improve usability through iteration: simplifying flows, reducing friction, improving clarity and completion rates.
• Ensure high quality: performance, responsiveness, cross-browser behavior, and pixel-level polish.

Requirements:

• Strong experience building production apps with React.
• Strong experience with React Query (caching, invalidation, pagination, optimistic updates, etc.).
• Strong UX/UI background: you understand product UX, visual hierarchy, spacing, typography, interaction design, and accessibility.
• Proven ability to design and ship complete features (not just implement tickets).
• Excellent communication and product sense: you can argue for UX improvements and make tradeoffs.
• Fluent English (B2-C1)

Preferred:

• EdTech experience (learning flows, content delivery, assessments/quizzes, progress tracking, analytics).
• Experience with complex UIs (editors, drag/drop, dashboards, real-time or collaborative interactions).
• Familiarity with design tools like Figma and turning systems into reusable UI.
• JavaScript, component libraries/design systems, and frontend testing.
• Experience using Cursor (or similar AI coding tools) to speed up implementation while keeping code quality high.
  

What success looks like

A UI that feels premium: intuitive, fast, consistent, and polished.

Learning experiences that reduce confusion and increase completion.

A scalable component system that speeds up shipping without losing quality.

Strong collaboration with backend so features feel seamless end-to-end.
