• Microcontroller experience (STM32, TI C2000, NXP, Infineon or similar)
• Motor control, control loops or sensor driver experience
• Shipped firmware to production or a field-tested prototype

Nice to have

• Field-oriented control, current sensing and encoder interfaces
• Functional safety (ISO 13849, IEC 61508)
• Battery management systems
• HIL testing, MISRA and CI for firmware
• Experience in robotics, drones, EV or industrial automation
