Full job description

Job Description: L2 Lab Server Operator

(Systems & Infrastructure)

Position Overview

We are seeking an experienced L2 Lab Server Operator to manage, maintain, and optimize

our non-production, R&D, and testing laboratory environments. In this role, you will be the

backbone of our lab infrastructure, ensuring high availability, performance, and security across a

diverse technical stack.

The ideal candidate possesses deep technical expertise in Wintel (Windows Server),

Enterprise Storage, VMware, and Hyper-V, alongside a strong engineering mindset to deploy,

troubleshoot, and automate complex lab topologies.

Key Responsibilities

1. Compute & Virtualization Management (VMware & Hyper-V)

Provision & Maintain: Deploy, configure, and lifecycle-manage virtual machines across

both VMware vSphere/ESXi and Microsoft Hyper-V environments.

Cluster Administration: Manage host clusters, configure high availability (HA),

Distributed Resource Scheduler (DRS), and live migrations (vMotion / Live Migration).

Resource Optimization: Monitor CPU, memory, and provisioned storage allocation to

prevent resource contention and optimize lab utilization.

Troubleshooting: Diagnose and resolve complex Layer 2 virtualization issues, including

host isolation, snapshot chains, and virtual switch (vSwitch) misconfigurations.

2. Wintel Administration

OS Lifecycle: Install, configure, and harden Windows Server operating systems (2016

through latest versions) within the lab environment.

Core Infrastructure Services: Administer and troubleshoot Active Directory (AD), Group

Policy Objects (GPOs), DNS, DHCP, and IIS configurations dedicated to the lab.

Patch & Compliance: Implement and maintain a rigorous patching cadence for Windows

servers utilizing WSUS or automated configuration management tools without disrupting

active lab testing.

3. Enterprise Storage Operations

Provisioning: Allocate and present storage blocks/shares (SAN/NAS) to virtualization

hosts and standalone bare-metal servers using protocols like iSCSI, Fibre Channel (FC),

and NFS/SMB.

Storage Management: Monitor storage array health, capacity, and performance.

Manage storage tiers, deduplication, and snapshots.

Backup & Recovery: Execute and verify routine backup configurations for critical lab

baselines, configurations, and data repositories to ensure rapid recovery capabilities.

4. Lab Operations & Support

Hardware Lifecycle: Perform physical rack-and-stack, cabling (fiber/ethernet), and bare-

metal provisioning of enterprise servers (e.g., Dell PowerEdge, HPE ProLiant).

Environment Isolation: Collaborate with networking teams to set up isolated VLANs,

routing, and firewall rules tailored for specific testing scenarios.

Automation & Scripting: Leverage PowerShell, PowerCLI, or Python to automate

repetitive tasks such as VM provisioning, environment teardowns, and status reporting.

Incident Management: Serve as the Tier 2 escalation point for all lab-related

infrastructure alerts, performance degradation, and hardware failures.

Qualifications & Skills

Technical Requirements

Education: Bachelor’s degree in Computer Science, Information Technology, or

equivalent hands-on experience.

Experience: 3–5 years of experience in system administration, infrastructure operations,

or data center environment support.

Virtualization: Strong proficiency in VMware vSphere (vCenter, ESXi) and Microsoft

Hyper-V / Failover Cluster Manager.

Operating Systems: Advanced administration of Windows Server ecosystems; familiarity

with Red Hat Enterprise Linux (RHEL) or Ubuntu is a plus.

Storage: Hands-on experience with enterprise storage platforms (e.g., NetApp, Dell

EMC, Pure Storage) and fabric switches.

Scripting: Proficiency in PowerShell for Windows and virtualization management.

Soft Skills & Work Environment

Adaptability: Ability to thrive in a fast-paced, fluid environment where lab configurations

change frequently based on engineering needs.

Problem-Solving: Strong analytical mindset with a methodical approach to root-cause

analysis.

Documentation: Diligent about keeping topology diagrams, asset inventories, and "how-

to" runbooks accurate and up to date.

Preferred Certifications (Any of the following are a plus)

VMware Certified Professional (VCP)
Microsoft Certified: Windows Server Hybrid Administrator Associate
Enterprise Storage certifications (e.g., NetApp NCA/NCDA, Dell Technologies Associate)
