Frontend Developer; m​/f​/d Energy Management System; Edge​/Cloud

Company Overview

We are Pramac, a Generac Company, leading the evolution to more resilient, efficient, and sustainable energy solutions.

In this role 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 mainly work with React, Type Script, 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 Graph

QL 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 parameterising 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 optimisations to the integration of native features.

You work with internationalisation (i18n) to provide our applications in a structured and sustainable multilingual set‑up. 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.
