We’ve been named a Leader by multiple analyst firms and have been globally recognized for Innovation, Product Strength, and Simplicity in Design. Join us on our mission to shape the future of our industry. We are seeking a Senior IT Infrastructure engineer who thrives in dynamic environments and can rapidly learn new platforms, embrace AI-assisted operations, and contribute across both lab and production infrastructure. Success in this role requires strong technical depth, operational ownership, collaboration, and a bias toward automation and continuous improvement. You'll work across Linux systems, Kubernetes clusters, kubevirt-based virtualization, and enterprise SAN storage. You will be expected to use AI tools to move faster, reduce toil, and catch issues earlier than a purely manual workflow would allow. This is not an "AI-optional" role.  We expect modern infrastructure engineers to pair deep systems knowledge with AI-assisted workflows for scripting, troubleshooting, documentation, and operational analysis. The judgment and systems expertise are still yours; AI is a force multiplier, not a replacement for understanding what's happening under the hood. What You'll Do Design, deploy, and maintain Linux server infrastructure (RHEL/Rocky/Ubuntu and similar) across production and non-production environments Operate and scale Kubernetes clusters: deployments, networking, storage integration, upgrades, and troubleshooting Manage kubevirt-based virtualization environments: VM lifecycle, resource allocation, live migration, performance tuning, and host maintenance Administer and optimize SAN storage systems (Pure Storage, Dell, HPE, and/or NetApp), including provisioning, performance, snapshots, and capacity planning Contribute to datacenter networking design and troubleshooting (VLANs, switching, routing fundamentals) where applicable Build automation and tooling to reduce repetitive manual work across the infrastructure stack Participate in on-call rotation and incident response, driving root-cause analysis for infrastructure issues Document architecture, runbooks, and operational procedures Participate in maintenance activities, platform upgrades, and infrastructure migrations across global data center locations How AI Fits Into This Role We expect you to actively use AI tools to augment (not replace) the skills above. This looks like: Scripting & automation : Using AI coding assistants (e.g., Claude Code, Copilot) to draft and refine automation for…
