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
Methane, that is mostly generated by flaring in the oil and gas industry, is a major contributor to global warming - as are the carbon emissions produced by global computing (especially bitcoin mining.) Crusoe Energy Systems reduces flaring, and repurposes waste natural gas into energy for these processes, thus removing methane from the atmosphere and simultaneously reducing the carbon footprint of computing.
Crusoe's mobile data centers can be deployed to generate power from methane waste at its source. As well as its patented Digital Flare Mitigation system, Crusoe is also working to enable alternative revenue streams for renewable and clean energy projects, with the ultimate aim to run data centers on renewable energy.
The company has connections with Kraken Oil & Gas, Devon Energy, Enerplus, and more; and its computing power is used by institutes such as MIT. The rising pressure to take action on climate change, coupled with the need for high-energy computing as more infrastructure moves online, has placed it in a massive industry. With the capability of its systems to reduce the equivalent of 8,000 tonnes per year of CO2 and 2023 debt financing amounting to $200 million in investment, Crusoe Energy Systems is well positioned to make an impact and drive for further success.
