Senior Systems Engineer

Your Team's Impact

The Virtualization Team is responsible for designing, deploying, and operating the virtualization layer that underpins FactSet's infrastructure — from traditional vSphere environments across our global data centers to a growing Kubernetes-native virtualization platform that serves as the foundation for our internal developer platform.

As a Senior Systems Engineer on this team, you will manage both our established VMware vSphere estate and help build and operate the next generation of our virtualization infrastructure using KubeVirt and Rancher Harvester. You will work closely with platform engineering, storage, networking, Kubernetes, and application teams to deliver reliable, high-performance infrastructure that supports thousands of workloads worldwide. The team has access to AI tools and actively uses them to accelerate automation development and improve incident response.

What You'll Do 

• Administer and evolve our KubeVirt and Rancher Harvester hyperconverged infrastructure as part of our internal developer platform
• Design, deploy, and operate vSphere environments across data centers, offices, global POPs, and remote client locations
• Manage VM lifecycle across both traditional and Kubernetes-native virtualization platforms, including live migration, capacity planning, and cluster maintenance
• Collaborate with platform and application teams to define and implement virtualization requirements for new and existing workloads
• Monitor, troubleshoot, and resolve performance and stability issues across vSphere, KubeVirt, and Harvester environments
• Design and maintain distributed storage systems (VSAN, Longhorn) supporting VM and container workloads
• Automate infrastructure lifecycle management using PowerShell, PowerCLI, and Kubernetes-native tooling (Terraform, GitOps/ArgoCD/Flux)
• Leverage AI tools to accelerate automation development, improve runbooks, and enhance incident response workflows
• Create and maintain process documentation to ensure operational efficiency and availability
• Plan and execute capacity expansions across both legacy and cloud-native virtualization stacks
• Participate in a periodic 24x7 on-call rotation. Global follow the sun strategy minimizes non-work hours interruptions.

What We're Looking For

• 5+ years of experience with VMware vSphere/ESXi administration
• Foundational understanding of Kubernetes concepts and cluster operations, or strong motivation to develop this expertise
• Experience with PowerShell and PowerCLI scripting and automation
• Strong technical, analytical, and communication skills
• Ability to manage multiple projects simultaneously and prioritize appropriately

CRITICAL SKILLS

• Kubernetes fundamentals: CRDs, operators, RBAC, networking, persistent volumes, and cluster lifecycle management
• Knowledge of VMware technologies: vCenter, vSphere/ESXi, and virtual infrastructure administration for mixed Windows and Linux guest environments
• Experience with KubeVirt or similar VM-on-Kubernetes solutions (libvirt, KVM, QEMU)
• Familiarity with hyperconverged infrastructure platforms, particularly Rancher Harvester
• Understanding of distributed storage systems (Longhorn, Ceph, or similar) including replication, snapshots, and recovery
• Advanced Kubernetes networking: CNI plugins, Multus CNI for multi-network VM configurations, network policies
• Experience with infrastructure-as-code and GitOps workflows (Terraform, ArgoCD, Flux)

ADDITIONAL / HIGHLY DESIRED SKILLS

• Knowledge of AWS/GCP public cloud services and hybrid infrastructure patterns
• Experience with container platforms and container runtimes (containerd, Docker)
• Familiarity with observability tooling: Prometheus, Grafana, and log aggregation platforms
• Knowledge of TCP/IP networking, DNS, LAN/WAN, load balancers, and firewalls
• Experience with non-vSphere hypervisors (KVM, Xen) beyond KubeVirt contexts
• Administer and evolve our KubeVirt and Rancher Harvester hyperconverged infrastructure as part of our internal developer platform

EDUCATION

• Bachelor's degree in Computer Science, Engineering, or equivalent experience
