• Develop, test, and maintain embedded software in C, C++, and relevant real-time programming languages for the HV battery management system, cells, and associated components.
• Implement sensor data acquisition, hardware abstraction layers, real-time communication, and diagnostics features.
• Collaborate with cross-functional teams in controls and electrical hardware to ensure cohesive system operation.
• Conduct software debugging, verification, and validation including model-in-the-loop (MiL), software-in-the-loop (SiL), hardware-in-the-loop (HiL), and trackside testing support.
• Create proper requirements and unit tests to form robust, clean, scalable code bases.
• Adhere to software quality, safety, and regulatory standards for high-performance motor sport applications.
• Maintain technical documentation and contribute to continuous improvement processes in embedded software development.

• Master’s or PhD in Electrical Engineering, Computer Science, Embedded Systems, or related discipline; OR
• Bachelor’s degree with 5+ years of experience in embedded software development, preferably in automotive or motor sport sectors.
• Expertise in battery management systems and battery control algorithms, such as protection/derating, state of charge, and state of health.
• Familiarity with cell and HV battery physics and operation.
• Understanding high voltage bus networks, including contractors, fuses, and high voltage interlock loops.
• Strong proficiency in embedded C programming and real-time operating systems, including ability to work with both handwritten and auto generated code.
• Experience with multithreaded processes/multi-rate control systems.
• Experience in communication protocols such as CAN, CAN FD, Ethernet, SPI, I2C, and UART.
• Familiarity with software development tools, debugging environments, and version control systems.
• Understanding of control theory (digital control loops and practical implementation issues) for electronic systems.
• Knowledge of embedded hardware interfaces, sensors, and microcontroller architecture.
• First principles thinking, strong problem-solving skills and attention to detail.
• Excellent teamwork, communication, and collaboration abilities.
• Proactive attitude toward continuous learning and innovation in embedded systems development.

• Understanding of functional safety standards (ISO 26262) and FIA F1 technical regulations is advantageous.
• Machine Learning/neural networks especially in the context of battery control systems.
• Embedded on chip machine learning.
• Knowledge of scripting languages (Python, MATLAB) for testing and automation.
• Prior experience with software-in-the-loop (SiL) or hardware-in-the-loop (HiL) testing and software validation frameworks.
• Experience in Functional Mock-up Unit (FMU) development and co-simulation techniques.
• Familiarity with TAG-700 ECU.
