Job Description

Your Responsibilities

• Define electrical requirements for power flow, protection, and monitoring components within our battery energy storage and power conversion systems
• Derive requirements from customer specifications, project constraints, risk assessments, and applicable IEC, EN, and VDE standards while ensuring alignment with mechanical, thermal, software, and integration requirements
• Perform electrical calculations and analyses including cable and busbar sizing, short-circuit behavior, voltage drop, thermal loading, protection coordination, insulation concepts, and fault scenarios
• Develop and contribute to electrical system architectures covering HV and LV distribution, communication interfaces, protection philosophies, fault handling, and system integration concepts
• Define testing and validation requirements, acceptance criteria, and compliance documentation while supporting FAT, SAT, certification, and customer compliance activities
• Support customer projects throughout the entire lifecycle, participate in design reviews, FMEAs, risk assessments, and hazard analyses, and coordinate electrical testing and commissioning activities

Your Profile

• Degree in Electrical Engineering, Energy Technology, Power Electronics, or a comparable field
• Several years of experience in high-voltage electrical systems, industrial power systems, machinery, energy storage, power conversion, e-mobility, aerospace, or comparable high-power applications
• Strong knowledge of relevant IEC, EN, and VDE standards (e.g: VDE 0113-1, 0100-410 and 0660-600-1) as well as deep expertise in HV design, protection concepts, grounding, insulation monitoring, short-circuit behavior, and thermal design
• Experience defining and reviewing technical requirements, electrical architectures, component specifications, validation plans, and verification evidence
• Proven ability to work effectively across multidisciplinary teams including engineering, product development, procurement, production, and customer project organizations, ideally with experience in battery energy storage systems or grid-connected power conversion systems
• Fluent in English and German, with experience using automation, scripting, or AI-based tools to improve engineering workflows considered a plus
