Frontend Developer Energy Management System (Edge/Cloud)

Together with your team, you design, develop, and enhance the web frontends of our Energy Management System - ranging from real-time visualization of energy flows and dashboard widgets to the control of battery storage systems, charging stations, and photovoltaic (PV) systems. You will mainly work with React, TypeScript, and Vite.

You develop, maintain , and document our component library (Design System), ensuring a consistent look & feel across projects - documented and visually testable using Storybook.

You create interactive data visualizations and charts to display energy consumption and generation, profitability analyses, and system states.

You integrate GraphQL interfaces to ensure type-safe communication with our backend services and guarantee performant , stable, and scalable data flows between frontend applications , Edge and Cloud APIs.

You implement complex forms and configuration interfaces - for example, for parameterizing battery systems, charge/discharge profiles, and simulation scenarios - with a strong focus on validation, usability, and intuitive user experience.

You support the deployment of our application as a mobile app for iOS and Android using Capacitor - from platform-specific optimizations to the integration of native features.

You work with internationalization (i18n) to provide our applications in a structured and sustainable multilingual setup.

You ensure the quality of our frontend applications with unit tests, component tests, end-to-end tests, and API mocking, and you contribute to the continuous improvement of our testing strategy.

You take full ownership of the design, implementation, documentation, and quality assurance of your software modules, ensuring their long-term maintainability, scalability, and high code quality.
