Company mission
To align the future of computing with the future of the climate.
Role
Who you are
- 5+ 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: C, Go, 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
What the job involves
- At Crusoe, we are building the most sustainable, AI-first cloud infrastructure, and our Compute-focused Site Reliability 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
Our take
Methane, that is mostly generated by flaring in the oil and gas industry, is a major contributor to global warming - as are the carbon emissions produced by global computing (especially bitcoin mining.) Crusoe Energy Systems reduces flaring, and repurposes waste natural gas into energy for these processes, thus removing methane from the atmosphere and simultaneously reducing the carbon footprint of computing.
Crusoe's mobile data centers can be deployed to generate power from methane waste at its source. As well as its patented Digital Flare Mitigation system, Crusoe is also working to enable alternative revenue streams for renewable and clean energy projects, with the ultimate aim to run data centers on renewable energy.
The company has connections with Kraken Oil & Gas, Devon Energy, Enerplus, and more; and its computing power is used by institutes such as MIT. The rising pressure to take action on climate change, coupled with the need for high-energy computing as more infrastructure moves online, has placed it in a massive industry. With the capability of its systems to reduce the equivalent of 8,000 tonnes per year of CO2 and 2023 debt financing amounting to $200 million in investment, Crusoe Energy Systems is well positioned to make an impact and drive for further success.
