About The Position

At Fluidstack, we’re 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. We’re 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 you’re motivated by purpose, obsessed with excellence, and ready to work very hard to accelerate the future of intelligence, join us in building what's next. The Role We are developing a direct current air cooled chiller program to support our next-generation AI data centers. As an Electrical Engineer focused on ACC, you will own the electrical architecture of our chiller platform. You will be responsible for power distribution, protection coordination, grounding strategy, and DC switchgear selection. This role requires deep expertise in DC power systems and the ability to design safe, reliable power distribution for a novel architecture.
