About the Role
As a Power Electronics Controls Engineer in the Advanced Engineering group, you will architect the future of data center infrastructure, designing innovative High and Low Voltage Direct Current (HVDC/LVDC) electrical systems. You will pioneer thermal and magnetic design solutions that ensure the reliable power delivery and operation of millions of GPUs.
The Focus
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
About You
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
