About the role
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 This Role: As a Software Engineer II - Software Defined Networking, you will lead the development and execution of our Software Defined Networking strategy. You will work extensively with the Linux Kernel, utilizing technologies such as XDP/EBPF, DPDK, SmartNIC, and DPU/IPU to drive innovation and performance improvements. What You’ll Be Working On: Develop and execute the roadmap for the Software Defined Networking strategy at Crusoe Cloud. Be highly hands-on, guiding the engineering team through architecture decisions, design processes, design reviews, code reviews, and implementation tasks. Collaborate with the network infrastructure organization to develop industry-leading networking infrastructure. Lead Linux Kernel and driver development, system architecture design, production support, and cross-functional collaboration. What You’ll Bring to
