How to Apply for Senior Systems Software Engineer

at Crusoe

🏢 About Crusoe

Crusoe is uniquely transforming stranded energy sources like flared natural gas into eco-friendly power for high-performance computing, specifically targeting AI data centers. Their mission directly addresses environmental impact while powering cutting-edge technology, making them a rare company where sustainability meets high-performance computing innovation.

About This Role

This Senior Systems Software Engineer role involves designing and optimizing Linux applications for managing virtualization across thousands of AI compute servers globally, with deep integration into hardware/software AI chip-vendor stacks. You'll be directly responsible for enhancing performance of the entire virtualization stack specifically for AI/ML workloads through low-level optimizations and profiling.

💡 A Day in the Life

A typical day involves collaborating with kernel and hypervisor teams to troubleshoot integration issues, profiling virtualization stack performance for specific AI workloads, and designing enhancements to manage thousands of AI servers across Crusoe's global data centers powered by stranded energy sources. You'll frequently interface with hardware vendors to optimize their stacks within Crusoe's unique compute environment.

🎯 Who Crusoe Is Looking For

  • Has hands-on experience building Linux applications with virtualization components, device drivers, and memory management (not just using existing systems)
  • Possesses deep hardware knowledge of GPUs, CPUs, Infiniband/Ethernet NICs, and PCI Express architecture relevant to AI/HPC environments
  • Demonstrates experience with distributed applications and scalable systems design using communications protocols and databases
  • Has worked on performance optimization of virtualization stacks, particularly for AI/ML workloads through profiling and low-level tuning

📝 Tips for Applying to Crusoe

1

Highlight specific projects where you optimized virtualization performance for AI/ML workloads, quantifying improvements in latency or throughput

2

Detail your experience with AI chip-vendor hardware/software stacks (NVIDIA, AMD, Intel, etc.) and how you've integrated with them

3

Demonstrate your understanding of Crusoe's unique energy-to-compute model by explaining how your skills could optimize their distributed data center operations

4

Showcase experience with both kernel-level work (device drivers, memory management) AND application-level distributed systems design

5

Include examples of working across multiple global datacenters or large-scale distributed systems, not just single-location deployments

✉️ What to Emphasize in Your Cover Letter

["Your experience with Linux kernel virtualization components and how you've built applications that interface with hypervisors", 'Specific examples of optimizing AI/ML workload performance through virtualization stack enhancements', 'How your hardware knowledge (GPUs, CPUs, NICs) translates to better virtualization management in AI/HPC environments', "Why Crusoe's mission of transforming stranded energy appeals to you and how your skills align with their unique compute infrastructure"]
