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. \nWe'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.\nWe hire people who care deeply about this problem space. If that is you, please apply!\nHow We Operate\nBe a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.\n\nInsane urgency. We drive everything forward as fast as possible.\n\nReason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.\n\nLove 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.\n\nBuild something that actually matters. If you're going to spend your time, spend it on something that matters to the world.\n\nThe Product Engineering Team\nProduct 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.\nExamples of key problems the team is working on:\nArchitect a medium-voltage solid-state transformer that can be manufactured, serviced, and scaled across gigawatt-scale campuses, not just demonstrated in a lab.\n\nDefine the interface between the SST and the MVDC distribution system, including protection, control boundaries, and fault behavior.\n\nBuild a semiconductor and magnetics supply strategy that survives a thin 10kV SiC market over a multi-year horizon.\n\nTake converter hardware from topology selection through working prototypes on a schedule that data center construction actually depends on.\n\nRole Scope\nArchitect the SST end to end, selecting the topology (ISOP DAB stacks, MMC-based, or another approach) and semiconductor strategy, with every choice defended on efficiency, redundancy, manufacturability, and device availability.\n\nLead the power electronics, magnetics, and controls engineers from architecture to working hardware, owning the technical decisions that get prototypes built rather than debated.\n\nOwn the system trade-offs and the interface with the MVDC systems team, writing down exactly where the SST stops and the system begins, precisely enough that both teams can design against it.\n\nBuild the program plan and prototype roadmap, and make the build-vs-partner recommendation honestly, including the case where partnering is the right answer.\n\nDevelop vendor and research partnerships across device makers, labs, and universities that secure the devices, test capacity, and expertise the program needs.\n\nWhat We're Looking For\nThe 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.\nYou have 15+ years in power conversion and have led an SST or MV converter program at the level of ABB/Hitachi Energy research, GE, Delta, EPRI, or a FREEDM/ETH/Aachen lineage lab.\n\nYou've owned converter topology selection, semiconductor strategy, and system trade-offs at MW scale, and can defend the choices you made.\n\nYou've led converter development teams from architecture through working hardware, not just papers or simulations.\n\nYou know the SiC ecosystem well enough to write a five-year semiconductor strategy in a market where 10kV devices barely exist.\n\nYou've lived through a program that died or nearly died, and you know exactly why, and what you'd do differently.\n\nYou can write a 12-month program plan for 8 engineers and defend it line by line.\n\nBonus: medium-frequency transformer design depth, MVDC system integration experience, established vendor and university research relationships, or certification exposure for MV power conversion.\n\nWe are committed to pay equity and transparency.\nFluidstack is an Equal Employment Opportunity Employer.
