Job description

Experience Level: 5-7 Years

Role Summary

Must Have Skills -Citrix, CVAD, PLM, ERP, CAD, and SCADA-linked apps, ESXi

The L3 Infrastructure Engineer will serve as the highest escalation point for a mission‑critical Citrix and VMware environment. In a manufacturing context, this role is vital for ensuring "Zero Downtime" for shop‑floor applications, shipping systems, and engineering workstations. You will lead the architecture, high‑level troubleshooting, and security hardening of the entire delivery stack, from the hypervisor to the NetScaler gateway.

Core Technical Responsibilities

Citrix Stack Management (XenApp/CVAD) Architecture & Design: Maintain and optimize a high‑availability Citrix Virtual Apps and Desktops (CVAD) site architecture.

Provisioning Excellence: Deep administration of PVS (Provisioning Services) for high‑speed streaming and MCS (Machine Creation Services) for cloud‑integrated/persistent workloads.

App Hosting: Manage specialized XenApp hosting for manufacturing‑specific software (PLM, ERP, CAD, and SCADA‑linked apps).

User Experience: Master‑level management of Citrix Profile Management (UPM), WEM (Workspace Environment Management), and StoreFront.Netscaler (Citrix ADC).

Traffic Management: Configure and manage Load Balancing (LB) for internal services and Global Server Load Balancing (GSLB) for multi‑site disaster recovery.

Access Gateway: Lead the administration of Netscaler Gateway for secure remote access, including AAA, nFactor authentication, and SSL Certificate management.

Troubleshooting: Expert use of Wireshark and Netscaler Insight/ADM to diagnose latency and connection failures.

Virtualization & Hypervisor (VMware) vSphere Mastery: Manage large‑scale ESXi clusters, vCenter 7.x/8.x, and distributed switches.

Capacity Planning: Perform resource optimization (CPU/RAM/Storage) to ensure VM performance does not impact manufacturing production lines.

Host Management: Perform firmware updates and host patching using Lifecycle Manager.

Windows Server & Other Core Services OS Lifecycle: Manage Windows Server versions from legacy 2012/2012 R2 (handling legacy shop‑floor apps) to modern 2019/2022 environments.

Active Directory: Advanced GPO (Group Policy) management, OU structures, and AD Site/Services optimization for low‑latency logins.

Network Services: High‑availability configuration and troubleshooting of DNS, DHCP, and IPAM.

VLAN & Networking: Practical knowledge of network segmentation. You must understand how Citrix traffic traverses different VLANs (e.g., Corporate vs. Production/IoT zones).

Site Survivability: Ensuring local site servers can continue to operate if the WAN link to the central data center fails.

Hardware Integration: Troubleshooting specialized peripherals (label printers, scanners, PLC interfaces) mapped through Citrix sessions.

Cybersecurity Basics: Implement "Least Privilege" access. Hardening of Citrix VDAs and Windows Servers using CIS benchmarks.

Threat Mitigation: Understanding of DDoS protection on Netscaler and securing the environment against lateral movement.

Audit Readiness: Maintaining logs for compliance and performing regular vulnerability patching (Patch Management).

MTTR (Mean Time to Resolution): Minimizing downtime for critical production‑line apps.

Uptime: Maintaining 99.9% availability for the Citrix and Netscaler infrastructure.

Automation: Percentage of manual tasks (like image updates or health checks) automated via PowerShell.

Certifications (Preferred): CCP-V (Citrix Certified Professional), CCE-V (Expert), VCP (VMware Certified Professional), or MCSE.

Tools: PowerShell (Advanced Scripting), Citrix Director, Citrix ADM, VMware vROps, and SolarWinds/SCOM
