Role
Who you are
- 8+ years of professional experience in SRE, systems, or networking engineering
- Hands-on experience with SDN platforms and protocols (e.g., Open vSwitch, ONOS, Tungsten Fabric, Calico, Cilium, EVPN/VXLAN)
- Proficiency in a programming language such as Python, Go, or C
- Experience with Infrastructure as Code and deployment tooling such as Terraform, Ansible, or Puppet
- Deep knowledge of Linux internals with a focus on networking subsystems, kernel modules, and packet scheduling
- Familiarity with network protocols such as BGP, OSPF, IS-IS, MPLS, and network virtualization technologies
- Strong experience working with containerized workloads and orchestration platforms (e.g., Kubernetes, Docker), particularly around CNI plugins and service networking
- Excellent incident response, troubleshooting, and documentation practices
- Experience with building and operating managed networking services at scale (AWS VPC, Transit Gateway, GCP VPC, Azure Virtual Network)
- Excellent communication skills
- Embody the Company values
What the job involves
- At Crusoe Energy Systems, our Site Reliability Engineering team plays a mission-critical role in maintaining the performance and reliability of our AI-optimized cloud infrastructure
- The SDN-focused SRE role is responsible for ensuring the availability, performance, and scalability of Crusoe’s cloud networking services, which power compute-intensive, latency-sensitive workloads for AI and HPC use cases
- This role directly supports our vertically integrated, sustainable cloud platform by building and optimizing distributed, fault-tolerant networking systems at scale
- In this role, you will build automation and self-healing tools to monitor and maintain Crusoe’s software-defined networking (SDN) infrastructure, which underpins Crusoe Cloud’s edge, backbone, and data center connectivity
- You will drive reliability initiatives focused on routing convergence, traffic engineering, policy enforcement, and fault isolation
- Collaborating closely with network engineers, you will help implement and maintain high-performance virtualized networking services (e.g., overlays, service meshes, programmable data planes) that support large-scale AI compute clusters
- Your responsibilities will also include supporting user-facing networking services with a focus on availability, latency reduction, performance tuning, and adherence to error budgets
- You’ll investigate and resolve networking-related incidents using deep telemetry, flow logs, and packet-level analysis, while also partnering with hardware and kernel teams to optimize network stacks, drivers, and control planes
- Additionally, you will contribute to the architecture of fault-tolerant, scalable SDN backends tailored for AI-first cloud environments
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.
