This role may be eligible for incentive pay and/or equity.

$208,000—$305,000 USD

Flexible time off, wellness resources, and company-sponsored team events.

5+ years in infrastructure or platform engineering, SRE, architecture, or field and solutions engineering roles

Must have Unix & Linux administrator experience

Deep Kubernetes expertise (CKA/CKS or equivalent), grounded in having run clusters in production rather than in a lab

Strong command of enterprise storage: Fibre Channel SAN (zoning, WWPNs, fabric login and path behavior), iSCSI, NVMe/TCP, NAS protocols, dm-multipath, LVM, and array-side provisioning, masking, and mapping

Real understanding of compute and server hardware: bare metal provisioning and lifecycle, BIOS, firmware and driver management, HBA and NIC selection, NUMA and CPU/memory topology, local NVMe layout and endurance

Production-grade virtualization knowledge

Plus an understanding of KubeVirt as a migration target

Practical data center networking: VLANs and trunking, MTU and jumbo frames, bonding and LACP, L2 versus L3 boundaries, routing, load balancer integration, and how partitions, congestion, and asymmetric paths present in a distributed storage system

Solid Linux systems background extending to the block and device layers: udev, kernel and sysctl tuning, systemd, I/O scheduling, and performance triage with tools like iostat, blktrace, and perf

Working understanding of customer development environments (CI/CD, application deployment patterns, dev and test workflows) sufficient to reason about platform needs beyond just the storage layer

Strong technical writing skills.

Prior "forward deployed," field engineering, or professional services experience a plus

Ideally VMware vSphere and ESXi (datastores, VMFS, vVols, HA and DRS behavior, resource contention)

Familiarity with cloud and managed Kubernetes platforms (EKS, AKS, GKE, OpenShift) is useful, since many customers run a hybrid footprint, but on-prem depth is what this role is built around

Prior experience with Portworx, other CSI-based storage platforms, or enterprise storage vendors (Pure Storage, NetApp, Dell, etc.) is highly valued
