Overview

Your career opportunity as SENIOR FRONT-END DEVELOPER FOR E-COMMERCE (m/f/d). Would you like to support the technical development of the hygi.de webshop within the existing system and help shape a long-term strategy? Are you also interested in gradually integrating modern architectural approaches (API-first, headless models, edge and cloud-native frontend architectures) into the existing platform? Then we have just the right opportunity for you! As a Senior Frontend Developer, you’ll contribute your technical expertise to a mature system, develop reusable components, and support the implementation of modern architectural approaches—with a focus on functionality, performance, and user experience.

• Implementation of high-performance, responsive, and accessible user interfaces
• Connecting the frontend to APIs and integrating it into existing systems
• Ensuring code quality through reviews, documentation, and clean architecture
• Analyzing and optimizing performance, usability, and technical SEO aspects

What You Bring To The Table

• Excellent knowledge of HTML, CSS (including CSS3 and SCSS), and Vue.js (or React), as well as proficiency with modern component frameworks
• Understanding of component-based architecture with a focus on reusability and clear separation of responsibilities
• Strong understanding of performance optimization and Core Web Vitals
• Proficiency in version control (Git)
• Experience with modern front-end build tools and toolchains (e.g., Encore, Webpack, Vite) as well as confident dependency management in npm/yarn/pnpm-based projects
• Excellent understanding of responsive web design and cross-browser compatibility
• Basic knowledge of technical SEO
• Basic understanding of accessibility (WCAG 2.2)
• Experience with REST/GraphQL APIs
• Thinking strategically, working independently, and always wanting to learn more: That’s exactly what sets you apart.
• With empathy and passion, you familiarize yourself with existing processes and systems to gradually improve them
• You’ll proactively contribute your technical expertise and come up with new ideas for optimizations

Desirable Additional Qualifications

• Knowledge of testing tools and methods (e.g., Cypress, Playwright, Vitest, Storybook)
• Interest in contemporary architectural approaches and modern e-commerce standards—particularly in the context of performance, delivery strategies, and dynamic content delivery (e.g., API-first, headless, composable architecture)
• Strong skills in graphical implementation based on design specifications, including the ability to independently adapt layouts when specifications are missing
• A basic understanding of API design, authentication, and system architectures is a plus
