Background:
The 21st century needs a 21st century healthcare system. To help build this, Roche is not only developing personalized medicine and advanced diagnostics, but also heavily investing into software and digital solutions. To speed up medical processes, make them safer and more accessible to a wide range of people. The team you're joining is working on solving healthcare application hosting at a large scale. Ultimately aiming at deploying and managing thousands, even tens-of-thousands of Kubernetes clusters around the world. If you are excited to shape the way healthcare is
working in the coming decade, we would love to welcome you in our highly skilled team -which strives to become a role model for the entire industry.

The perfect candidate:
We are seeking a Senior UX/UI Engineer who possesses exceptional coding expertise and a profound understanding of user experience design. In this role, you'll be a key player in shaping our product's future, translating complex problems into elegant, intuitive, and high-performing
user interfaces that delight our users.

Tasks & Responsibilities:
• Architect, build, and maintain reliable, scalable, and beautifully crafted features for our core applications using React, TypeScript, and modern CSS.
• Be a key player in the entire design & development lifecycle from wireframing through to deployment and maintenance.
• Collaborate closely with product managers and backend engineers to transform complex requirements into clean, high-quality, and maintainable code.
• Integrate seamlessly with our REST APIs to deliver robust user facing features.
• Champion and evolve our frontend best practices, ensuring high standards for code quality, performance, accessibility, and testability.

Must Haves:
• 5+ years of professional experience building complex, user-facing web applications.
• Deep expertise in the modern JavaScript ecosystem, including React (Hooks, Context, State Management) and TypeScript.
• Proven experience in UI/UX design principles, with the ability to create wireframes or high-fidelity prototypes to guide development.
• A genuine passion for crafting exceptional, user-centric experiences within a complex environment. Willingness and drive to understand technical "business domains": you bring (end-user) experience in containerization & the Kubernetes ecosystem, e.g. because you were deploying frontend applications yourself using a Kubernetes cluster.
• Knowledgeable with CSS frameworks, preprocessors (e.g., Sass or Less), styled components.
• Familiarity with our core stack tools: ViteJS, TanStack Query, and Zustand.
• Experience with CI/CD pipelines (e.g., GitLab CI).
• Hands-on experience working with and integrating REST APIs effectively.
• Proficiency in writing meaningful, robust tests using frameworks like Vitest and React Testing Library.
• Excellent communication skills in English (German would be a plus) and collaboration skills.
