Frontend Developer (m/f/d) Energy Management System (Edge/Cloud) 

PRAMAC is part of a globally operating energy technology company and is at the forefront of innovation in Battery Energy Storage Systems (BESS). Our solutions – stationary and mobile – enable energy independence, grid stability, and sustainable energy supply. 

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
