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

Required

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
