Software Engineer, Infrastructure Platform

ABOUT FLUIDSTACK At Fluidstack, we build the compute, data centers, and power that will fuel artificial superintelligence. We work with Anthropic, Google, Meta, AMI Labs, and Black Forest Labs to deploy gigawatts of compute at industry defining speeds. We are investing tens of billions of dollars in US infrastructure. In 2026, we will deploy 1GW. In 2027, 10GW. Our team is small, fast, and obsessed with quality. We own outcomes end-to-end, challenge assumptions, and treat our customers' problems as our own. No task is beneath anyone here. There are a few thousand people who will shape the trajectory of superinteligence. Come and be one of them. ABOUT THE ROLE Fluidstack, a leading cloud provider, is looking for a Software Engineer, Infrastructure Platform to build the foundational platforms that enable our global infrastructure and data center operations.
