$200k - $230k/yr
Responsibilities
- Design and implement embedded control systems for PFC, grid-tie and grid-forming inverters, bidirectional chargers, DC/DC converters, and related power electronics.
- Develop control firmware and algorithms for power converters, including PLLs, timers, PWMs, harmonic cancellation, and accurate real-time operation.
- Validate designs using computer simulations, hardware-in-the-loop modeling and testing, and hands-on laboratory testing.
- Create automated HIL test cases, including plant modeling, hardware interfaces, fault injection, scripting, and result analysis.
- Perform board bring-up and develop device drivers for CAN, I2C, SPI, UART, Ethernet, and other peripherals.
- Contribute to specifications and design reviews, perform unit testing, and debug complex firmware and hardware issues.
- Ensure power-converter designs comply with applicable safety and regulatory requirements, including UL, IEC, and SAE standards.
Requirements
- 7–10 years of proven experience developing power electronics products.
- At least 6 years of programming experience in C/C++, Assembly for 32-bit controllers, DSPs, and Python for scripting and automation.
- Experience implementing power-converter control code without relying on code-generation tools.
- Strong experience designing controllers such as PI, PR, and droop controllers, with modeling and simulation using PLECS, MATLAB, and Simulink.
- Extensive experience developing timing-critical real-time firmware involving PLLs, timers, PWMs, and related control functions.
- Experience developing harmonic-cancellation algorithms using feedback approaches.
- Strong embedded C/C++ firmware experience for real-time systems and solid knowledge of power-electronics control techniques for inverters, rectifiers, LLC, CLLC, DAB, PFC chargers, and DC/DC converters.
- Experience with grid-tie inverter systems such as solar, BESS, or EVSE applications.
- Hands-on high-power laboratory experience and ability to debug firmware-related hardware issues in power converters.
- Experience programming microcontrollers and using timers, PWM, interrupts, GPIOs, ADC, UART, I2C, SPI, CAN, and Ethernet; TI C2000 DSP experience is a plus.
- Experience with Git or SVN version-control systems, RTOS, HIL testing, oscilloscopes, logic analyzers, debuggers, and FPGA programming and simulation.
- Familiarity with renewable energy, electric-vehicle charging, or energy-storage technologies is highly valued.
Benefits
- Base salary range of $200,000–$230,000 per year, plus eligibility for new-hire and annual merit-based RSU grants.
- Health, dental, and vision insurance, 401(k), paid time off, parental leave, life and disability insurance, and wellness resources.
- The role is located in Campbell, California, with compensation potentially adjusted based on work location.
- The company provides reasonable accommodations throughout the employment process and supports an inclusive, diverse workplace.
