Staff Production Engineer, Crusoe Energy Systems

• 8+ years of professional experience in Compute SRE, Linux system engineering, or compute infrastructure roles
• Strong proficiency in Linux kernel internals, with exposure to scheduler, memory allocation, and driver subsystems
• Experience with virtualization architectures and technologies such as KVM, Xen, QEMU, or VMware
• Familiarity with SmartNICs/DPUs (e.g., NVIDIA CX6/7, BlueField-3) and kernel bypass techniques
• Expert-level skills in at least one programming language: Go, C or Rust
• Experience with system-level debugging, including kdump, kexec, and kernel panic analysis
• Proficiency in Infrastructure as Code tooling and CI/CD practices for bare-metal or cloud infrastructure
• Strong understanding of compute scheduling, resource management, and high-throughput networking

Desirable

• At Crusoe Energy Systems, we are building the most sustainable, AI-first cloud infrastructure, and our Compute-focused Production Engineers are the backbone of that mission. This role is centered on supporting virtualization, hypervisor, and kernel-level performance for Crusoe’s compute infrastructure. You’ll play a vital role in deploying and optimizing bare-metal and virtualized compute platforms, ensuring performance, security, and scale for modern AI and HPC workloads
• In this role, you will develop automation and observability tools to monitor Crusoe’s compute infrastructure, spanning from the kernel to orchestration layers. You will support and scale the company’s virtualization stack, including technologies such as KVM, QEMU, and other hypervisors. Collaborating with Linux kernel and hardware teams, you’ll help identify and resolve performance bottlenecks, driver issues, and optimize hardware offloads
• A key focus will be on optimizing performance for AI and HPC workloads across CPU, GPU, and DPU/NIC resources. You will participate in root cause analysis for kernel crashes, hardware-software integration problems, and performance regressions, while also integrating hypervisor-level enhancements to improve guest VM reliability and workload isolation. The role involves tuning kernel subsystems such as the process scheduler, NUMA configuration, memory management, and interrupt handling. Additionally, you will work closely with platform teams to implement and validate support for emerging compute hardware, including SmartNICs, BlueField devices, and TPUs
