Reports ToSr. Manager, Power Electronics Firmware
What You Will Be DoingChargePoint is looking for an experienced Power Electronics Controls and Firmware Engineer with more than seven years of hands-on expertise in developing embedded firmware for power control applications. The preferred candidate will excel as an individual contributor supporting our rapid growth. Advanced skills in writing C code for microcontrollers, DSPs, and FPGAs. Candidates with a background in power electronics systems and familiarity with renewable energy, electric vehicle charging, or energy storage technologies are highly valued. We are seeking someone with strong capabilities in Control Engineering and Power Electronics for next-generation fast-charging solutions.
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- 7 - 10 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 PLLs, timers, PWMs, etc.
- Strong experience in developing algorithms for harmonic 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
