About the Position

We are hiring a Frontend Developer to build user-facing layers of web applications using React or Vue. Join our team in Morges, Switzerland, for a remote position.

Responsibilities

You’ll be the person who turns designs and data into interfaces people actually enjoy using. Our projects are often complex - scheduling tools, analytics dashboards, real-time views - and we need a frontend developer who’s as comfortable with data-heavy UIs as they are with clean, accessible design implementation.

Build reusable UI components using a modern JavaScript framework (React, Vue, or similar)
Implement complex data interfaces: filterable tables, charts, calendar views, and modal workflows
Integrate with backend APIs and manage client-side state effectively
Connect real-time updates via WebSocket clients where needed
Implement internationalisation (i18n) for multilingual applications
Ensure responsive design, cross-browser compatibility, and accessibility (WCAG 2.1 AA)
Work from Figma designs and collaborate with designers on feasibility and details
Participate in sprint reviews and client feedback rounds

Requirements

Personality

You have a good eye - you notice when things are slightly off and you fix them
You care about the user experience, not just the code
You communicate well with designers and backend developers alike
You’re methodical about browser compatibility and edge cases
You take feedback well and iterate quickly

Experience

3+ years of frontend development experience
Strong skills in React or Vue - hooks, component composition, performance optimisation
Experience with utility-first CSS frameworks (e.g. Tailwind CSS)
Experience building data-heavy UIs: tables, filters, pagination, sorting, charts
Solid understanding of REST API consumption and client-side state management
Comfortable working from Figma designs
Awareness of web accessibility standards (WCAG)
Comfortable with modern frontend build tools (Vite, Webpack)

Nice to Have

Experience with full-stack frameworks like Inertia.js, Nuxt, or Next.js
Familiarity with charting or data visualisation libraries
Experience with WebSocket clients and real-time UI updates
i18n implementation experience

Education

Bachelor’s degree in Computer Science, Design, or equivalent practical experience
Fluent in English; French is a plus
