About The Position

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster. We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI. 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. If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe. About the Role: The Crusoe Cloud Managed AI team seeks an ambitious and experienced Senior Software Engineer to join their team. You'll have a pivotal role in shaping the architecture and scalability of our next-generation managed AI services. You will lead the design and implementation of core systems for our AI offerings, including resilient fault-tolerant queues, model catalogs, and scheduling mechanisms optimized for cost and performance. This role offers the opportunity to build and scale critical infrastructure capable of handling millions of API requests per second across thousands of customers. The team is working on building the next chapter of products to accelerate the process of adding intelligence into software. This is an on-site role based in San Francisco, CA, or Sunnyvale, CA, requiring in-office presence.
