How to Apply for Principal Software Engineer, SDN Networking
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, making this role ideal for engineers passionate about combining cutting-edge networking with environmental innovation.
About This Role
This Principal Software Engineer role involves developing the SDN strategy for Crusoe Cloud while leading Linux kernel/driver development and network programming. You'll architect industry-leading networking infrastructure that supports their sustainable data centers, making this position critical for scaling their eco-friendly computing platform.
💡 A Day in the Life
You might start by reviewing SDN architecture designs with the engineering team, then dive into Linux kernel debugging for network performance issues. Later, you could collaborate with infrastructure teams on packet processing pipeline optimizations using XDP/EBPF, ensuring Crusoe's sustainable data centers maintain industry-leading networking performance.
🚀 Application Tools
🎯 Who Crusoe Is Looking For
- Has 10+ years building production systems at scale with deep expertise in C/C++/Rust system programming and Linux internals
- Possesses hands-on experience with kernel bypass technologies (XDP/EBPF, AF_XDP, DPDK) and network accelerators
- Demonstrates expert knowledge of TCP/IP, packet processing pipelines, and SDN architecture decisions
- Can guide engineering teams through architecture reviews while collaborating with network infrastructure organizations
📝 Tips for Applying to Crusoe
Highlight specific experience with kernel bypass technologies (XDP/EBPF, DPDK) in production environments at scale
Demonstrate how your SDN experience aligns with sustainable computing or energy-efficient infrastructure
Showcase leadership in Linux kernel/driver development with concrete examples from previous roles
Connect your network programming expertise to Crusoe's mission of transforming stranded energy
Provide metrics showing how your work improved network performance or reliability in previous production systems
✉️ What to Emphasize in Your Cover Letter
