The opportunity
Crusoe is on a mission to accelerate the abundance of energy and intelligence . As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads.
What you'll do
SDN Execution & Roadmap Contribution: Contribute to and help refine the technical direction for Software-Defined Networking, translating strategy into concrete plans, milestones, and measurable outcomes for your area of ownership.
Architecture & Design: Participate in and help lead architecture reviews, author design documents for major SDN components, and provide thorough code reviews for critical services.
Kernel & Driver Optimization: Build and optimize Linux kernel modules and high-performance drivers using technologies such as XDP, eBPF, AF_XDP, and DPDK.
Fabric Design: Help design and implement network architectures for GPU-to-GPU fabrics, high-speed Ethernet, and specialized AI clusters.
Hardware Integration: Implement and tune virtualization features such as SR-IOV, vDPA, and virtio, and help integrate advanced SmartNICs, DPUs, or IPUs into the stack.
Performance Engineering: Troubleshoot complex production issues and perform deep performance tuning to maximize throughput and minimize latency and improve future designs based on learnings.
What they're looking for
- Technology Evaluation: Evaluate emerging SDN and NFV technologies, and contribute to open-source projects where strategically relevant, sharing findings with the broader engineering org.
- Mentorship: Mentor engineers across the stack, review their designs and code,: and help build a culture of engineering excellence.
- Cross Functional: Partnering with software and operation teams to implement, execute, deploy and manage your architecture designs while incorporating feedback along the way.
- High-Performance Networking Experience: 8+ years of experience building and operating large-scale networking systems in production, ideally within cloud or hyperscale data center environments.
