Energy Conversion Systems & Software Engineer (m/f/d)

What you will do in this role:

Take responsibility for end-to-end energy conversion functionalities, from customer requirements to 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 development of functionalities.

Create and maintain system requirements, functional architectures, interface definitions and behavioral models using modern engineering methods and tools.

Conduct simulation, testing and validation activities, moving functionalities from virtual models to real verification in high-voltage laboratories.

Ensure traceability, documentation quality and compliance with automotive development processes such as ASPICE and functional safety standards.

Represent the system perspective to internal stakeholders and customers, helping to resolve technical challenges and align cross-functional teams.

Required skills and experience:

Degree in systems engineering, electrical engineering, computer science or a related technical discipline.

Several years of experience in embedded systems development, ideally in systems 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 SysML 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, as well as automotive development processes such as ASPICE and ISO 26262.

Excellent communication and coordination skills, combined with the ability to take responsibility, lead technical topics autonomously and work effectively within multidisciplinary teams.
