Systems Software Engineer

Systems Software Engineer 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: The Crusoe Cloud Software Development team is seeking a passionate and experienced Senior/Staff Software Engineer specializing in Systems Applications. This pivotal role is critical in the design and development of our compute platform, specifically focusing on building compute applications for virtualized AI-platforms. An understanding of the linux kernel, virtualization, hardware tuning, distributed systems, object oriented programming, and low-level systems programming are critical to this role. Excellent communication skills and a desire to work with a wide range of technologies across the linux stack are both a must. This is a full-time position. WHAT YOU’LL BE WORKING ON: - Compute Application Development & Scaleout: Design highly reliable and performant Linux applications used to manage our virtualization stack across thousands of AI compute servers in multiple global datacenters. - AI Hardware Platform Integration: Integrate Crusoe applications with a wide variety of hardware and software AI chip-vendor stacks. Build solutions to optimize and monitor virtualized hardware (GPUs, Infiniband/ROCe NICs, Ephemeral Storage, etc.) in cutting-edge AI/HPC environments. - Kernel & Hypervisor Integration - Work side by side with our Linux Kernel and Hypervisor teams to ensure our Crusoe applications are seamlessly integrated with a variety of kernels and hypervisors. - Performance Analysis & Tuning: Analyze and enhance the performance of the entire virtualization stack, from the hypervisor to the virtualized guest OS, with a specific focus on optimizing AI/ML workloads. This includes profiling, bottleneck identification, and implementing low-level optimizations. - System-Level Troubleshooting: Diagnose and resolve complex system issues across our virtualization stack (drivers, kernel, hypervisor, guest OS, and crusoe applications). Work closely with kernel and hypervisor teams to debug and resolve integration challenges. - Code Review and Quality Assurance: Conduct thorough code reviews to ensure the highest level of software quality, reliability, and security within compute applications and virtualization stack. - Cross-Functional Collaboration: Collaborate with other engineering teams, including hardware design, OS development, and AI/ML application teams, to ensure cohesive and integrated product development. - Technical Leadership: Provide technical guidance and mentorship to junior engineers, fostering a culture of technical excellence and collaborative problem-solving within the compute applications team. WHAT YOU’LL BRING TO THE TEAM: - Linux Systems Familiarity: Experience building applications on Linux kernels, specifically pertaining to virtualization, device drivers, memory management, and process scheduling ...
