Your Mission as a Full Stack Engineer

We're looking for product-minded engineers to join our diverse and driven team. We really value collaboration, making an impact, and continuous learning. Our product development team is based in Berlin, but we have folks working all over Europe, and you'll work closely with an experienced and supportive team.

Your Role and Responsibilities

You’ll thrive in this Full Stack Engineer role if you enjoy building intuitive, responsive, and performant user interfaces while collaborating closely with backend and data teams. You’ll feel right at home if you can:

• Build modern, scalable web applications using React, TypeScript, and CSS, with a strong focus on user experience and accessibility.

• Maintain high standards of code quality, performance, and responsiveness across different devices and browsers.
• Contribute to and evolve our design systems, component libraries, and frontend architecture.
• Troubleshoot and resolve bugs or performance issues across the stack.
• Help shape a cutting-edge development environment with tools like CI/CD, automated testing, and version control best practices.
• Occasionally dive into backend code (Golang) or infrastructure (Terraform, GitHub Actions) when needed to unblock progress.
• Know your way around AI (its strengths and weaknesses).

What You'll Need to Be Successful in This Full Stack Engineer Role

• Frontend Expertise: Strong hands-on experience with React, TypeScript, and CSS (Styled Components, Redux Toolkit, React Testing Library, Jest, Storybook, Cypress and Playwright).
• Full Stack Awareness: Understanding of backend services, APIs.
• Collaboration: A proactive communicator who enjoys working in cross-functional teams and explaining technical topics to non-technical colleagues.
• Problem Solving: Analytical thinking, attention to detail, and a bias for action.
• Communication: Clear, concise, and confident communication in English.
