• Develop high-quality, optimized C/C++ code for real-time embedded applications
• Work with real-time operating systems (RTOS) and bare-metal firmware
• Implement communication protocols such as CAN, SPI, I2C, and Modbus
• Ensure CI/CD pipelines, automated testing, and version control (Git, Bitbucket) are integrated into the software development lifecycle
• Develop a structured software architecture for embedded control applications
• Ensure modular, reusable, and scalable software components across different motor drive platforms
• Work with AUTOSAR (if applicable) and maintain adherence to ISO 26262 (functional safety)
• Collaborate with hardware teams to define software-hardware interfaces
• Develop test strategies including unit testing, system testing, software-in-the-loop (SIL), and hardware-in-the-loop (HIL) simulations.
• Create test matrices to validate control algorithms and ensure overall product performance
• Analyze and review test data from simulations and real-world scenarios

Your Qualifications

• University degree in power electronics, electrical engineering, SW engineering or a related field (M.Sc. or similar).
• Several years’ experience in motor control software development for PM motor drives
• Strong proficiency in C/C++ programming for embedded real-time applications
• In-depth knowledge of control algorithms for sensorless control, FOC, and PWM techniques
• Understanding of embedded hardware including analog/digital interfaces, microcontrollers, and DSPs
• Experience with automotive development including the Aspice model
• Experience in model-based development (MBD) using Matlab/Simulink
• Experience AUTOSAR with safety-critical software (ISO 26262, IEC 61508)
• Experience with automated testing frameworks and HIL/SIL methodologies
• Ability to read technical German and communicate effectively in English

Your Profile

• Well-organized, structured, and detail-oriented with the ability to close tasks on time
• Strong problem-solving and analytical skills
• Trustworthy and good in close follow up
• A team player as well as able to work independently

Working Hours

• Variable working time + willingness to travel abroad – about 10 – 15 days per year
