Original job description

ABOUT FLUIDSTACK

We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. If that is you, please apply!

HOW WE OPERATE

Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.
Insane urgency. We drive everything forward as fast as possible.
Reason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

THE PRODUCT ENGINEERING TEAM

Product Engineering builds the power and cooling systems that let Fluidstack deliver gigawatt-scale AI data centers faster and denser than the grid-standard supply chain allows. The SST group is designing solid-state transformers as a core building block of that power architecture.

Examples of key problems the team is working on

Architect a medium-voltage solid-state transformer that can be manufactured, serviced, and scaled across gigawatt-scale campuses, not just demonstrated in a lab.
Define the interface between the SST and the MVDC distribution system, including protection, control boundaries, and fault behavior.
Build a semiconductor and magnetics supply strategy that survives a thin 10kV SiC market over a multi-year horizon.
Take converter hardware from topology selection through working prototypes on a schedule that data center construction actually depends on.

ROLE SCOPE

Write the control firmware for every SST cell and block: modulation, closed-loop voltage and current control, and voltage sharing across dozens of series-stacked cells.
Build the fast protection path that detects a fault and shuts the converter down within microseconds, from sensing to safe state.
Sequence startup, precharge, cell bypass, and the reconfiguration of the output from 800 V to 1,500 V.
Connect cell controllers to the block master and the site control system across isolation barriers, with telemetry operators can act on.
Prove the firmware on hardware-in-the-loop rigs before it runs on a high-voltage prototype.

WHAT WE'RE LOOKING FOR

The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would. https://jobs.ashbyhq.com/fluidstack/05c2e69c-42f9-4fcb-9cf0-a467aaf98f1c

You've written control firmware that runs a power converter at full power, and debugged it on the bench with a scope in hand.
You've controlled resonant or dual active bridge converters, or balanced series-connected cells.
You've built protection logic in an FPGA or DSP that trips in microseconds and fails safe.
You've used hardware-in-the-loop or model-based design to catch bugs before they reached hardware.
You keep firmware in version control with reviews and automated tests, and can show the release history of something you shipped.
Bonus: Embedded targets for power control (TI C2000, Xilinx or Intel FPGAs). Model-based design (MATLAB/Simulink, PLECS). Hardware-in-the-loop platforms (Typhoon HIL, OPAL-RT). Industrial communication (CAN, EtherCAT, fiber links). Functional safety practice (IEC 61508, MISRA C).

We are committed to pay equity and transparency.
