In this position, you will:

• Lead system engineering and integration of our solar solutions into customer vehicles (e.g. refrigerated trailers, vans, trucks, buses), defining system architectures and coordinating cross-functional engineering activities
• Drive the technical execution and delivery of customer projects, ensuring both pilot and series solutions meet technical, operational, and commercial expectations
• Act as the primary technical interface to OEM and Fleet customers, supporting them throughout the entire project lifecycle
• Contribute to the development of new solar products, including feasibility studies, concept development, and requirements engineering, as well as the integration of key system components such as PV modules, charge controllers, and telematics
• Develop wiring diagrams and system topologies and conduct D-FMEA analyses to identify and mitigate technical risks

• Define and implement validation and testing strategies to ensure system performance and reliability

• Proven ability to manage technical projects including timelines, risks, and budgets
• Willingness to travel occasionally to customer and project sites
• Passion for sustainable technologies and the mobility transition
