Power Conversion System Engineer (m/f/d)

E-Mobility is the future. Become a part of it! Join us in Buchs, canton St. Gallen (CH), immediately or by arrangement as a What you will move in this role: Take ownership of power conversion features end-to-end, from customer requirements through architecture, implementation alignment, and final system verification. Design and define control functions, modulation concepts, fault reactions, and system behavior for high-power electronic converters. Collaborate closely with hardware, software, FPGA, and test engineers to ensure seamless integration and consistent feature development. Create and maintain system requirements, functional architectures, interface definitions, and behavioral models using modern engineering methods and tools. Drive simulation, testing, and validation activities, taking features from virtual models into real-world verification in the high-voltage laboratory. Ensure traceability, documentation quality, and compliance with automotive development processes such as ASPICE and functional safety standards. Represent the system perspective towards internal stakeholders and customers, helping to resolve technical challenges and align cross-functional teams. What skills and experience you should bring: Degree in Systems Engineering, Electrical Engineering, Computer Science, or a related technical discipline. Several years of experience in embedded systems development, ideally in system engineering, software, FPGA, hardware development, or power electronics applications. Good understanding of power electronics, control systems, modulation methods, and the interaction between hardware and software in real-time systems. Experience with MATLAB/Simulink, Stateflow, or similar modeling tools; knowledge of Sys ML or System Composer is an advantage. Solid understanding of embedded software concepts, including C programming, communication protocols (e.g., CAN), and real-time system behavior. Familiarity with requirements engineering, system architecture development, verification and validation, and automotive development processes such as ASPICE and ISO 26262. Strong communication and coordination skills, combined with the ability to take ownership, drive technical topics independently, and work effectively across multidisciplinary teams.
