Software Engineer (Frontend / Full Stack)
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.
Job Description
This role is centered on developing modern, high-performance frontends for a suite of enterprise-grade applications. As part of a cross-functional team, you will collaborate closely with external teams.
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.
What you'll do
* 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.
What we're looking for
* React and modern frameworks such as Next.js, Remix, or Vite, ideally within large-scale enterprise environments.
* 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.
* Experience with various rendering strategies - SSR, CSR, SSG, and ISR - and their impact on performance, scalability, and SEO.
* Experience with modular applications (Redux, Zustand, or React Context API).
* 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 with Actions, GitLab CI / CD, Terraform, and Kubernetes.
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 Node.js, Python, or Java, and an understanding of full-stack collaboration patterns.
* Fluency in Spanish, both written and spoken.
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.
