Role
Who you are
- The ideal candidate is a "builder" at heart
- 15+ years of progressive experience in large-scale network engineering, with at least 5+ years in a leadership role focused on network design, architecture, or development
- Deep expertise in Data Center Fabric Design: Proven track record building large-scale Clos topologies using BGP, EVPN-VXLAN, and Segment Routing
- Specialized HPC Knowledge: Deep understanding of the "Backend Network," including RDMA, RoCEv2, and InfiniBand, and how they impact GPU performance
- Software-Defined Mindset: Strong background in network programmability and automation frameworks (Python, Go, Terraform, Ansible, NetBox, or custom-built controllers)
- Hardware Proficiency: Experience with merchant silicon architectures (Broadcom Tomahawk/Jericho, Barefoot Tofino) and deep-buffer switching
- Architectural Vision: Ability to design for the future, including IPv6-only fabrics, multi-tenant security at the hardware level, and 800G/1.6T transitions
- Interconnect Expertise: Experience designing private backbones and peering strategies that integrate seamlessly with hyperscale cloud providers (AWS, GCP, Azure)
- Education: Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field
What the job involves
- Crusoe Cloud is seeking a visionary and technical leader to spearhead Network Development across our global infrastructure
- While our Operations team ensures the reliability of our current fleet, the Network Development team is responsible for the design, engineering, and evolution of the high-performance fabrics that make Crusoe a leader in AI and HPC
- You will lead the team responsible for translating complex architectural requirements into scalable, automated, and high-performance network designs
- From optimizing GPU-to-GPU communication in our HPC clusters to developing the automation frameworks that deploy our global backbone, you will be at the forefront of networking for the AI era
- Lead Network Engineering & Design: Own the end-to-end development lifecycle of Crusoe’s network architecture, focusing on the next generation of GPU fabrics and global interconnects
- Innovate HPC & AI Fabrics: Drive the engineering of low-latency, high-bandwidth networks (RoCEv2, InfiniBand) specifically optimized for massive-scale distributed AI training
- Define the Automation Roadmap: Architect and implement "Network-as-Code" initiatives. Lead the development of CI/CD pipelines for network configurations, automated provisioning, and self-healing infrastructure
- Hardware Strategy & Vendor Engineering: Evaluate and certify next-generation hardware platforms. Partner with vendors (Arista, NVIDIA, Juniper) to influence product roadmaps and ensure Crusoe has the best-in-class silicon for our workloads
- Build and Mentor a Development Culture: Recruit and lead a team of Network Development Engineers (NDE) and Software Engineers who bridge the gap between traditional networking and software engineering
- Cross-Functional Product Partnership: Collaborate closely with Product, Hardware Engineering, and Network Operations to ensure new designs are not only high-performance but also observable and maintainable at scale
Our take
Crusoe is tackling one of the biggest challenges facing the digital age: the enormous energy demand of data centres and AI infrastructure. As AI models grow more powerful, they require immense computing power (and therefor electricity) to train and operate. This surge in energy use has put some pressure on power grids, driven up costs, and raised environmental concerns. Crusoe is on a mission to make this process more sustainable by finding smarter, cleaner, and more efficient ways to power the data centres that drive modern computing.
The company started out by putting wasted energy to work. Originally known as Crusoe Energy, it captured natural gas that would otherwise be burned off ("flared") at remote oil sites and used it to power modular data centres. Today, Crusoe has evolved into a major player in AI infrastructure, designing and operating large-scale data centres near renewable or stranded energy sources. It's now one of a handful of "neocloud" companies (next-generation cloud providers focused on flexible, efficient computing for AI workloads). And its facilities are helping tech giants like OpenAI handle the massive computing requirements of training advanced AI models.
Recently, Crusoe has attracted some huge investor attention, tripling its valuation to over $10B and raising $1.4B in its latest funding round. It's building OpenAI's first major US data centre campus and even experimenting with bold new frontiers. In partnership with Starcloud, Crusoe plans to deploy the world's first space-based cloud computing infrastructure, powered by solar energy and orbiting the Earth by 2027. If successful, this could redefine how and where computing happens, opening up a cleaner, virtually limitless source of energy for AI's next generation.
