Do you enjoy getting hands-on with modern web technologies and developing high-quality software? Then you are exactly right for our Engineering Team!\nAs a Frontend Developer, you are an integral part of a cross-functional team and report to your Team Lead Engineering. You work closely with your teammates, product management, as well as UX and other specialist departments to realize innovative and customer-oriented solutions.\n\nYour Mission\nYou develop high-quality and scalable frontend architectures with passion and technical expertise. Through your commitment, you contribute significantly to implementing technical innovations and continuously improving the User Experience (UX).\nYour focus is clearly on the Web Frontend with React and TypeScript. At the same time, you are curious about neighboring technologies: Your know-how (or your interest) in Flutter helps us bridge the gap between Web and Mobile App and leverage synergies.\n\nYour tasks in detail\nTechnical Responsibility & Development:\nAnalyze, design, and implement new features for our online shops – from the first idea to going live.\n\nDevelop performant, reusable components in React and TypeScript and ensure a pixel-perfect implementation of sophisticated UI/UX designs.\n\nUse your understanding of mobile development (Flutter) to promote professional exchange with the App Team and ensure consistent user journeys across Web and App.\n\nConduct code reviews and promote the application of Clean Code and Test-Driven Development in the frontend.\n\nRecognize technical debt and derive targeted measures for its reduction.\n\nQuality Assurance & Best Practices:\nEnsure high development standards, test processes (Unit, Integration, E2E tests), and technical documentation.\n\nOptimize the performance of our web applications (Core Web Vitals) and ensure accessibility (a11y).\n\nIdentify and actively support the maintenance and optimization of frontend build pipelines and test environments.\n\nCollaboration & Planning:\nWork closely with product management and your team to specify requirements, realistically estimate development efforts, and implement solutions effectively.\n\nActively participate in decisions regarding technological direction and bring in suggestions for selecting suitable tools and frameworks in the React ecosystem.\n\nOperations & Infrastructure:\nSupport the operation and monitoring of the applications you have developed (Monitoring, Error Tracking).\n\nActively help to continuously improve CI/CD processes for the frontend.\n\nWhat you bring\nAt least 3 years of practical experience in frontend development, ideally in an e-commerce environment.\n\nExcellent knowledge of TypeScript and React as well as modern HTML and CSS (SASS/LESS, CSS-in-JS, or Tailwind).\n\nAn advantage: Knowledge of Flutter and Dart. You understand the concepts of mobile development and can exchange ideas on an equal footing with our mobile developers or even support them punctually.\n\nFamiliarity with architectural concepts such as Micro-Frontends, Domain Driven Design (DDD), or Self-Contained Systems is an advantage.\n\nKnowledge of handling REST APIs as well as GraphQL.\n\nBroad experience with CI/CD tools, container technologies (Docker), and an affinity for agile working methods.\n\nA high degree of quality awareness for Clean Code, tests (e.g., Jest, Cypress, Playwright), and technical documentation.\n\nStrong communication skills, openness to constructive feedback, and a cooperative way of working.\n\nActive exchange within the developer community as well as the willingness to regularly bring new knowledge and innovative ideas to the team.\n\nWe’re probably not a great match if you...\nPrefer frameworks like SAFe or projects that kick off with a rigid set of formal specifications (Lastenheft).\n\nHave worked primarily in highly regulated industries without experience in fast-paced, product-led environments and distributed systems.\n\nFeel more comfortable in role models where infrastructure, backend, frontend, testing, and product thinking are strictly siloed.\n\nExpect requirements to be handed to you fully \"ready to go,\" instead of refining them alongside Product Management and striving to truly understand the customer.\n\nView professional development mainly as the employer's responsibility, rather than learning out of your own curiosity—whether that’s on the job, at an evening event, or simply by picking up a book.\n\nAre more frustrated than motivated by imperfect systems—spoiler alert: we aren't \"there\" yet.\n\nStrictly separate work from having a good time.\n\nTech stack\nTypeScript\nHTML\nReact\nCSS\nJavaScript\nFlutter","description_format":"text","description_chars":4785,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Professional
