In this role, you will develop and maintain embedded firmware for the digital control of industrial power electronics, including systems using SCRs and IGBTs to generate regulated DC and AC output power. You will architect and implement firmware for real-time control on MCUs, DSPs, or FPGAs using C/C++ or similar low-level languages, and apply control algorithms for voltage, current, power, and thermal regulation in digitally controlled power converters. Responsibilities also include implementing firmware-level protection, monitoring, and diagnostic features to support industrial power reliability requirements. In addition, you will participate in technical reviews and contribute to documentation, coding standards, and version control practices, while supporting product validation, manufacturing transitions, and field troubleshooting as needed. The ideal candidate will be comfortable debugging complex embedded systems in lab environments, collaborating cross-functionally with hardware, systems, and product teams to define software requirements and interface specifications. The position requires occasional travel up to 10%.

Qualifications include a bachelor's degree in Electrical, Computer, or Controls Engineering or a related field, with 3+ years of experience in embedded controls, embedded software, or real-time systems. Strong skills in C/C++, RTOS environments, and digital control of industrial power converters are required, along with experience using microcontrollers or DSPs and working directly with hardware such as ADCs, PWMs, timers, and interrupts. Candidates should also understand power electronics and control theory and be comfortable using standard lab tools. Experience with embedded web servers and web interface development is a plus.
