Role
Who you are
- We are looking for a highly skilled engineer with deep experience running Kubernetes at scale on bare metal
- 10+ years in infrastructure engineering, including 3+ years operating Kubernetes in production
- Expert-level knowledge of Linux internals (cgroups, namespaces, kernel networking)
- Deep experience with CNIs (Cilium, Calico), load balancers (Envoy, HAProxy, F5), and L3 networking (BGP, ECMP)
- Strong programming skills in Go for building operators, controllers, and automation tooling
- Hands-on experience with distributed storage systems (Ceph, MinIO, Rook, CSI drivers)
- Strong background in observability (Prometheus, Alertmanager, metrics autoscaling, logging/ELK)
- Familiarity with PKI, identity, and secrets management (Vault, cert-manager)
- Excellent debugging skills for complex distributed systems
- Strong communication and collaboration across cross-functional teams
Desirable
- Strong experience running Kubernetes on bare metal (not just managed services)
- Proven track record provisioning and operating physical servers at scale (PXE/iPXE, Tinkerbell, MAAS, BMC/IPMI automation)
- Experience with hardware fleet management across multiple datacenters
- Contributions to open source Kubernetes or related ecosystem projects
- Experience implementing disaster recovery strategies at scale
- Familiarity with GPUs, HPC clusters, or large-scale AI/ML workloads
What the job involves
- You will help design, build, and operate Crusoe’s next-generation Kubernetes platform across global datacenters, ensuring performance, reliability, and automation at every layer of the stack
- Designing, building, and operating Kubernetes clusters on bare metal at scale
- Engineering full cluster lifecycle management (Talos bootstrapping, upgrades, node reprovisioning, HA control planes, recovery workflows)
- Architecting networking, load balancing, and service mesh solutions optimized for bare metal
- Implementing performant CNIs (Calico, Cilium), integrating L2/L3 networking, routing (BGP/ECMP), and optimizing traffic across racks and datacenters
- Automating provisioning via PXE/iPXE, Tinkerbell, MAAS, and managing BMCs/IPMI/Redfish with standardized BIOS/firmware across heterogeneous hardware fleets
- Designing and operating persistent storage (local disks, block, object) including Ceph, Rook, and openEBS
- Building automation and tooling (Go, Python, Bash) for provisioning, drift detection, upgrades, and incident response
- Extending observability with Prometheus, Alertmanager, Grafana, OpenTelemetry, and defining SLOs for cluster health, latency, and workload availability
- Implementing security best practices: Vault, cert-manager, RBAC hardening, network policies, and OS/K8s patch pipelines
- Mentoring engineers and shaping technical direction for Crusoe’s Kubernetes platform
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.
