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.
