Senior Infrastructure Engineer L3 (Citrix VDI)

This is a remote position.

• Own the golden image and machine catalog lifecycle: build, patch, test, and release images with minimal user disruption, and roll back cleanly when a release goes wrong.
  
• Troubleshoot session, profile, and application delivery problems end to end, including logon duration, profile containers, printing, peripherals, and protocol performance.
  
• Manage the access layer for each platform, including gateways, brokers, certificates, and MFA integration.
  
• Serve as technical lead during VDI-impacting incidents, coordinating with clients, internal teams, and vendors, and drive resolution without reliance on further escalation.
  
• Right-size host pools and delivery groups using session and resource data, and manage autoscale, power management, and cloud consumption.
  
• Automate recurring work such as image builds, catalog updates, and health checks using scripting and platform APIs.
  
• Write formal root cause analyses, execute changes through structured change management, and maintain documentation of baselines, images, and tuning decisions.
  
• Lead technical delivery of VDI projects including scoping, estimation, design, migration, and implementation.
  
• Give client stakeholders clear status reporting and practical best-practice guidance on their VDI environments.
  
• Mentor junior engineers and work with infrastructure, network, and service desk teams so VDI fits the wider environment rather than sitting beside it.
  
  

• 12+ years in infrastructure engineering with at least 3 years focused on VDI or end-user computing platforms, in roles where you owned the platforms rather than only supported users on them.
  
• MUST BE fluent in English
  
• Hands-on ownership of at least one enterprise VDI platform at depth: Citrix Virtual Apps and Desktops or DaaS, Azure Virtual Desktop, or Omnissa Horizon, including its access layer, image lifecycle, and profile management.
  
• Working familiarity with the other two platforms and the ability to come up to speed on them quickly.
  
• Strong Windows Server and Windows client administration, including Group Policy, Intune, and profile management.
  
• Working knowledge of the compute, storage, and networking layers beneath VDI, such as VMware vSphere or Azure, shared storage, load balancing, DNS, and certificates.
  
• Automation ability using AI tooling, scripting (PowerShell or an equivalent), and direct work against platform APIs.
  
• Experience writing formal root cause analyses and working inside a structured change management process.
  
• Clear client-facing communication and the ability to work independently across many client environments at once without losing track of any of them.
  
• Prior MSP or other multi-client experience, ideally supporting several customer environments at once.
  
• Associate's or bachelor's degree in information technology or a related field, or equivalent hands-on experience.
  
  

• Citrix, Microsoft (AZ-140), or Omnissa VDI certifications, or a comparable virtualization certification.
  
• Experience with application layering or packaging and with GPU-backed or graphics-intensive workloads.
  
• Experience with VDI monitoring and analytics tooling such as Citrix Director, ControlUp, or Azure Monitor.
