About the Position

Karriere bei Kainjoo

Wir stellen ein:

Frontend Developer

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.

Responsibilities

• 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

Persönlichkeit

• 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

• Country: Schweiz
• Remote: Yes
