Ab sofort

At TÜV Rheinland, we're in the midst of a major greenfield rewrite of a large-scale enterprise frontend application. This project spans a multi-application environment, involving a complex e-commerce & service system, multilingual support, and multinational requirements—all built as a modern, headless enterprise architecture.

We're looking for engineers who can contribute to both the frontend and full-stack aspects of these initiatives. You'll work closely with internal teams and external partners to help deliver high-performance, scalable digital products.

This role is centered on developing modern, high-performance frontends for a suite of enterprise-grade applications. As part of a small, cross-functional team, you will collaborate closely with large external partners and internal stakeholders to design and implement solutions using JavaScript, TypeScript, and React. Your contributions will span both core architecture and feature development across a complex, multilingual, and multinational digital ecosystem.

Success in this position goes beyond technical execution. You'll be actively involved in architectural planning, design system implementation, and the ongoing refinement of our development workflows. Working alongside product, design, and backend teams, you'll help build a scalable, maintainable frontend foundation that supports long-term growth and team efficiency.

Job Description

Build and maintain frontend applications with a focus on scalability, performance, and long-term maintainability.

• Develop modular, reusable components using React, TypeScript, and Storybook.
• Collaborate on an enterprise-grade atomic design system in Figma, working closely with designers and product owners.
• Write clean, maintainable code and contribute to architectural decisions, including documenting solutions and technical rationale.
• Create and maintain technical documentation, including architecture diagrams and internal docs using tools like Confluence and Jira.
• Collaborate effectively in Agile teams distributed across time zones, with strong async communication and team alignment.

What we're looking for

The final role level (e.g., Engineer II, Sr. Engineer, Staff Engineer) will be determined based on your experience, technical depth, and overall scope of contribution. We welcome candidates across a range of seniority, from mid-level professionals to highly experienced engineers.

• Solid experience with React and modern frameworks such as Remix, or Vite, ideally within large-scale enterprise environments.
• Strong proficiency in JavaScript (ES6+) and TypeScript, with the ability to write type-safe, modular, and maintainable code across frontend projects.
• Proficiency in enterprise-level Git workflows, with experience in managing large-scale mono-repos or multi-repo architectures.
• Deep understanding of CSS, ideally with modern CSS-in-JS solutions like PostCSS or Styled Components.
• Familiarity with implementing accessibility standards (WCAG) and ensuring cross-browser compatibility.
• Experience with various rendering strategies—SSR, CSR, SSG, and ISR—and their impact on performance, scalability, and SEO.
• Comfortable implementing and managing state management solutions in modular applications (Redux, Zustand, or React Context API).
• Deep experience with RESTful and GraphQL APIs in distributed environments, including custom integrations and caching mechanisms like Redis.
• Familiarity with schema validation using libraries like Zod, including use cases beyond form handling.
• Familiarity with frontend tooling and developer workflow utilities such as ESLint, Prettier, npm, and Husky for maintaining code quality and consistency.
• Proficient in using Jest, React Testing Library, Cypress, or similar tools to write meaningful unit, integration, and end-to-end tests; familiar with TDD practices.
• Experience working in Docker-based development environments, with a strong understanding of CI / CD pipelines and familiarity with DevOps tooling such as GitHub Actions, GitLab CI / CD, Terraform, and Kubernetes.
• Strong communication and collaboration skills, with the ability to conduct thoughtful code reviews, mentor team members, and clearly explain complex technical concepts to both technical and non-technical stakeholders.
• Demonstrated ability to produce clean, maintainable, and well-documented code, aligned with industry best practices and scalable architecture.
• Proactive in troubleshooting and debugging across the stack, and committed to staying current with the latest trends in modern frontend architecture.

Requirements

A degree in Computer Science or equivalent professional experience (typically 4+ years in industry)

• Fluency in English, both written and spoken - English is the primary language of our international team.
• Nice-to-haves.
• Experience working with headless CMSs (e.g. Contentful, Sanity, FirstSpirit, Strapi) in enterprise-scale systems.
• Experience building, maintaining, or optimizing enterprise-grade CI / CD pipelines, including deployment automation and environment orchestration.
• Previous involvement in leading teams, technical initiatives, or owning complex feature sets end-to-end.
• Previous exposure to backend development using Python or Java, and an understanding of full-stack collaboration patterns.

What can we offer you?

To belong to a solid international business project, with opportunities for professional development and a strong focus on people.

• Job stability with an indefinite and full-time contract.
• Participative and inclusive work environment with implementation of hybrid models of presence in the office and at home.
• Access to a flexible salary package with tax advantages, competitive at market level and with bonuses for achievement of objectives and contribution to results.
• Individual development plan to improve professional and personal skills that enhance talent management and the defined professional career.
