Reports To Sr. Manager, Power Electronics Firmware

Responsibilities

• What You Will Bring to ChargePoint
• Design and implement embedded control systems for power factor correction (PFC), grid-tie, grid-forming inverters, bidirectional chargers, DC/DC converters, and related power electronics.
• Stay updated on advancements in digital control technologies and controllers.
• Validate design concepts through both computer simulations and hands-on laboratory testing.
• Create automated test cases for hardware-in-the-loop (HIL) modelling and testing, where applicable.
• Perform board bring-up activities and develop device drivers for communication protocols such as CAN, I2C, and SPI.
• Contribute to specification development, participate in design reviews, and carry out unit testing.
• Ensure a thorough understanding of safety and regulatory requirements for power converters used in fast charging applications.
• Guarantee compliance with relevant regulatory and safety standards, including UL, IEC, and SAE.

Requirements

• 6+ years of proven experience developing Power Electronics products
• 6+ years of programming experience in C/C++, Assembly for 32-bit controllers, DSP, and Python for scripting and automation
• Demonstrated experience implementing control code for power converters without relying on code generation tools.
• Strong experience in designing controllers (such as PI, PR, droop, etc.), modelling, and simulation using tools such as PLECS, MATLAB, and Simulink, as well as lab tests.
• Extensive background in designing FW that requires accurate timing within a real-time programming environment, including PLL, timers, PWMs, etc.
• Strong experience in developing algorithms for harmonics cancellation using feedback approaches.
• Solid background in developing embedded firmware for real-time systems using C/C++.
• Strong grasp of power electronics principles, including control techniques for inverters, rectifiers, and DC-DC converters (LLC, CLLC, DAB, PFC chargers, DC/DC, inverters, etc.).
• Experience working with grid-tie inverter systems (solar, BESS, EVSE, etc.).
• Solid hands-on experience in high-power labs, with the ability to debug hardware issues related to firmware functions in power converters.
• Skilled in programming microcontrollers and using peripherals like timers, PWM, interrupts, GPIOs, ADC, UART, I2C, SPI, CAN, and Ethernet; experience with TI C2000 DSP family is a plus.
• Familiar with version control systems such as Git and SVN.
• Experience in hardware-in-the-loop (HIL) testing, including testbed setup, real-time simulation, plant modelling, hardware interfaces, test scripting, fault injection, and test result analysis.
• Proven skills in debugging complex firmware issues using oscilloscopes, logic analysers, and debuggers.
• Experience working with real-time operating systems (RTOS).
• Proficient in FPGA programming and simulation techniques
• Location
• Campbell, CA
• ChargePoint is committed to fair and equitable compensation practices. The targeted US sal
