Job Description Job Description Direct Hire opportunity for a Power Electronics Controls Engineer to join an Advanced Engineering group to help architect the next generation of data center infrastructure. You will lead the design of cutting-edge HVDC and LVDC systems while pioneering thermal and magnetic solutions that enable reliable, large-scale GPU operations. Location: San Francisco, CA Salary: $200,000-$300,000 per year, depending on experience, skills, qualifications Benefits: Retirement or pension plan, Health, dental, and vision, and PTO Relocation assistance provided for the right candidate Responsibilities Design and implement control algorithms for high-power DC-DC converters and active front-end systems in HVDC/LVDC architectures serving multi-gigawatt GPU computing loads. Develop digital control loops including voltage and current mode control, state-space controllers, and protection algorithms for bi-directional power flow management. Implement PWM modulation schemes, soft-switching control (ZVS/ZCS), and interleaving strategies for parallel converter operation at 10-100kHz switching frequencies. Design grid synchronization and power management algorithms for utility-connected systems, including phase-locked loops, active/reactive power control, and fault ride-through functionality. Validate control algorithms through simulation (MATLAB/Simulink, PLECS) and Hardware-in-the-Loop testing, then implement on embedded platforms (TI C2000, FPGA, DSP). Lead controls integration and compliance testing to utility interconnection standards (IEEE 1547, UL 1741) and take products through certification and production ramp. Qualifications 7 years of hands-on experience designing control systems for power electronics including DC-DC converters, active rectifiers, or grid-tied systems. Expert-level proficiency in C/C++ embedded programming for real-time control on microcontrollers, DSPs, or FPGAs with interrupt-driven architectures. Strong foundation in digital control theory including compensator design, loop stability analysis (Bode, Nyquist), and small-signal modeling of power converters. Proven track record with simulation tools (MATLAB/Simulink, PLECS, SPICE), scripting (Python), and Hardware-in-the-Loop platforms for controls validation. Deep understanding of PWM techniques, gate driver control for SiC/GaN devices, current sensing, and protection algorithm implementation. Experience shipping power electronics products from prototype through compliance certification, with hands-on board bring-up and troubleshooting skills.
