How to Apply for Systems Software Engineer

at Crusoe

🏢 About Crusoe

Crusoe uniquely transforms stranded energy (like flared natural gas) into eco-friendly power for data centers, significantly reducing environmental impact. They're pioneering sustainable computing infrastructure specifically for AI workloads, making them an ideal workplace for engineers passionate about both cutting-edge technology and environmental sustainability.

About This Role

This Systems Software Engineer role involves designing highly reliable Linux applications to manage virtualization across thousands of AI compute servers globally, with deep integration into hardware/software AI chip-vendor stacks. You'll optimize the entire virtualization stack for AI/ML workloads through profiling and low-level optimizations, directly impacting the performance and efficiency of Crusoe's sustainable AI infrastructure.

💡 A Day in the Life

A typical day involves designing and optimizing Linux applications for Crusoe's virtualization stack, profiling AI workload performance across thousands of servers, and collaborating with kernel/hypervisor teams to resolve integration challenges. You'll work on low-level optimizations while integrating with various AI hardware vendor stacks, balancing immediate troubleshooting with long-term system architecture improvements.

🎯 Who Crusoe Is Looking For

  • Has hands-on experience building Linux applications with virtualization, device drivers, memory management, and process scheduling at kernel level
  • Possesses deep understanding of AI hardware ecosystems including GPUs, CPUs, Infiniband/Ethernet NICs, and PCI Express architecture
  • Demonstrates experience with both high-level languages (Golang, Java, Python) and low-level systems programming (C, C++)
  • Has worked on distributed applications and scalable systems design with practical knowledge of communications protocols and database systems

📝 Tips for Applying to Crusoe

1

Highlight specific projects where you optimized virtualization stacks for AI/ML workloads, quantifying performance improvements

2

Demonstrate your understanding of both hardware (GPUs, NICs, PCIe) and software layers by describing integration challenges you've solved

3

Showcase experience with Linux kernel-level programming, not just user-space applications

4

Include examples of diagnosing complex system issues across virtualization stacks and collaborating with kernel/hypervisor teams

5

Emphasize any experience with sustainable computing or energy-efficient systems, aligning with Crusoe's environmental mission

✉️ What to Emphasize in Your Cover Letter

['Your experience with Linux kernel programming and virtualization stack optimization for AI workloads', 'Specific examples of integrating applications with hardware/software AI chip-vendor stacks', 'How your background in both high-level and low-level programming languages applies to this role', "Why Crusoe's mission of sustainable computing resonates with your professional interests"]
