About the Role

In this role, you will shape the user experience of a modern web application that gives engineers and planners at a German transmission system operator clear, fast access to technical asset information. You will own the interface of a data-heavy product, from importing and validating structured data to filtering and visualizing it, working side by side with backend and content platform specialists.

  • Integrate the application with Sitecore XM Cloud or a comparable headless CMS to deliver managed content reliably
  • Implement bulk import and export of structured data (for example from Excel), including validation, filtering, and visualisation
  • Structure the UI as microfrontends, using Tailwind CSS and Radix UI components to keep it consistent and easy to extend
  • Collaborate closely with designers, backend engineers, and client stakeholders to turn business needs into usable features
  • Set up and maintain CI/CD pipelines in Azure DevOps and deploy to Microsoft Azure
  • Contribute to code reviews and share frontend best practices within the team

Requirements

  • 5+ years of professional frontend development experience
  • 3+ years of hands-on experience with React, Next.js, and TypeScript
  • 1+ year of experience with headless CMS platforms, preferably Sitecore XM Cloud or comparable
  • Proven experience with microfrontend architectures and with backend-for-frontend implementations using Nest.js
  • 3+ years of experience working with REST and GraphQL APIs
  • Solid knowledge of HTML and CSS in modern web applications, including Tailwind CSS and UI component libraries such as Radix UI or comparable
  • Experience developing data-intensive web applications, including bulk data processing
  • Practical experience with Microsoft Azure and Azure DevOps, including CI/CD pipelines
  • Experience with monorepo-based development environments
  • Scalable frontend architectures in enterprise environments
  • Frontend performance optimization
  • Fluent German (C1) and very good English for working with the client, joining technical discussions, and writing documentation
