The opportunity
Join our RD team and help keep our power conversion products performing at their best across their full lifecycle. You will work in a cross-functional environment alongside engineering, manufacturing, quality, procurement, project management, and external partners to resolve complex technical issues and drive continuous product improvement.
In this role, you will provide advanced technical support for power electronics products used in renewable energy and energy storage applications. You will analyze complex problems, interpret schematics and converter behavior, support commissioning and laboratory testing, and prepare clear technical documentation. Your work directly improves the reliability, maintainability, and cost-effectiveness of products deployed worldwide.
To excel, you bring strong product understanding, hands-on troubleshooting skills, and the analytical mindset needed to read schematics, debug signals, and trace root causes. You communicate clearly across functions, document rigorously, and enjoy turning recurring issues into lasting product improvements.
You will grow by engaging with the full product lifecycle, from prototype and customer tests through certification, commissioning, and field support. You will build deep expertise across power converters, energy storage systems, and validation environments while collaborating with global engineering, quality, and product teams.
