To strengthen our software team, we are looking for a technology-driven professional who wants to actively shape the future of energy with us. Your Responsibilities – What You Can Expect * 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. What You Should Bring * A degree in Computer Science, Media Informatics, Technical Informatics, or a comparable field of study. * Very good knowledge of modern frontend technologies and tools, especially React, TypeScript, and Vite. * Solid experience with state management, GraphQL, and component-based architecture. * Confident use of UI component libraries and modern CSS approaches is an advantage. * Experience in cross-platform development is a plus. * Knowledge of testing frameworks and experience with Storybook to ensure high code quality are desirable. What You Can Expect From Us * Work on forward-looking technology with high relevance for the energy transition. * Diverse and engaging tasks in a motivated, international team. * Opportunities for further training and professional development in the fields of energy storage technology and digitalization. * Flat hierarchies, fast decision-making processes, and room for your own ideas. Location: * Murcia, Spain If you feel you have the right skill set to meet the role then please do not hesitate to contact us. We want to hear from you! #J-18808-Ljbffr
