Power Electronics Controls Engineer - Advanced Engineering

Fluidstack • Austin, TX

13d • $200,000 - $300,000

About The Position

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.

Requirements

• 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

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

Benefits

• The salary range for this position is $200,000-$300,000 per year, depending on experience, skills, qualifications, and location.
• Total compensation may also include equity in the form of stock options.
