Principal Systems Software Engineer
Crusoe — San Francisco, California, United States · In-Person · Staff+ · $260k - $340k/yearly
Role description
Role Overview
As the Principal Systems Software Engineer, you will serve as the visionary lead for Crusoe’s next-generation AI infrastructure. This is a role for an industry-recognized expert who has already 'seen the movie' at hyperscale and is ready to redefine the I/O path for the age of generative AI. You aren't just building a cloud; you are designing the fluid fabric that unifies Bare-Metal-as-a-Service (BMaaS), Intelligent IaaS, and Elastic CaaS into a single, high-performance pool of intelligence.
What You Will Do
Unifying Infrastructure Pillars: Bare-Metal-as-a-Service (BMaaS), Intelligent IaaS, and Elastic CaaS. Mastering the I/O Path: Lead the architectural design of our internal cloud fabric, drawing on experience from top-tier hyperscalers to drive the technical roadmap for SR-IOV, RDMA, and virtualized GPU scheduling.
Why It Might Be a Fit
We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services.
