About Fluidstack

At Fluidstack were building the infrastructure for abundant intelligence. We partner with top AI labs governments and enterprises - including Mistral Poolside Black Forest Labs Meta and more - to unlock compute at the speed of light.

Were working with urgency to make AGI a reality. As such our team is highly motivated and committed to delivering world-class infrastructure. We treat our customers outcomes as our own taking pride in the systems we build and the trust we earn. If youre motivated by purpose obsessed with excellence and ready to work very hard to accelerate the future of intelligence join us in building whats next.

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
