Accountabilities
- Citrix Architecture and Design: Design, document, and maintain comprehensive Citrix virtualization architectures covering Citrix Virtual Apps and Desktops (CVAD), Citrix DaaS, hybrid environments, multi-site deployments, and disaster recovery configurations. Develop high-level and low-level designs, reference architectures, technical standards, and implementation guides.
- Infrastructure Capacity and Scalability: Define capacity planning, infrastructure sizing, scalability, and high-availability strategies for Delivery Controllers, StoreFront, NetScaler/ADC, Cloud Connectors, and Virtual Delivery Agent (VDA) workloads. Ensure architecture decisions support performance, resilience, and business continuity.
- Secure Remote Access: Design and maintain secure remote access solutions using NetScaler Gateway/ADC, incorporating authentication technologies such as SAML, multi-factor authentication (MFA), and Microsoft Entra ID, while aligning with Zero Trust security principles.
- Advanced Technical Troubleshooting: Act as the Tier 3 and final technical escalation point for complex, high-severity Citrix incidents. Lead root cause analysis for issues involving slow logons, session launch failures, black screens, session reliability, HDX and graphics performance, VDA registration, and profile management.
- Diagnostic Tools and Vendor Coordination: Use advanced troubleshooting tools such as CDF Control, Citrix Director, WEM Analytics, Wireshark, Process Monitor (ProcMon), Windows Event Logs, and Citrix Scout. Collaborate with Citrix Support and other technology vendors, including Microsoft, hypervisor, storage, and networking providers, to resolve critical issues.
- Upgrade and Migration Leadership: Lead end-to-end CVAD upgrade projects, including Long Term Service Release (LTSR) and Current Release (CR) upgrades. Manage assessments, prerequisites, testing strategies, pilot deployments, production cutovers, and rollback planning. Oversee Citrix DaaS migrations, onboarding, and hybrid-to-cloud transitions.
- Platform Component Management: Plan and coordinate upgrades across StoreFront, NetScaler/ADC, Licensing Server, Director, WEM, Provisioning Services (PVS), Machine Creation Services (MCS), VDA components, and master images.
- Project Delivery and Change Management: Develop project plans, timelines, risk registers, and communication strategies. Coordinate with project managers and infrastructure, security, and application teams to ensure successful implementation with minimal downtime. Maintain compliance with change management procedures, including CAB approvals, change records, and post-implementation reviews.
- Profile Management Strategy: Evaluate and define the organization's strategy for Citrix Profile Management (UPM) versus Microsoft FSLogix, considering logon performance, scalability, storage consumption, resilience, and compatibility with Microsoft Office, OneDrive, and Teams.
- Profile Architecture and Migration: Design profile storage architectures using SMB, NetApp, and Azure Files, including Cloud Cache, VHD(X) locations, folder redirection, and exclusions. Lead profile migration projects, pilot testing, performance tuning, and user acceptance testing. Establish best practices for profile sizing, antivirus exclusions, and monitoring.
- Proof of Concepts and Innovation: Lead proof-of-concept (POC) initiatives and pilot deployments for emerging technologies, including Citrix DaaS, WEM, App Layering, Citrix Analytics, cloud-hosted VDAs, GPU/HDX 3D Pro, Windows 11 multi-session, and Citrix Secure Private Access.
- Solution Evaluation and Deployment: Define measurable POC objectives, test cases, success criteria, and expected outcomes. Present recommendations supported by technical, financial, and risk assessments. Lead approved solutions through design, development, testing, production deployment, and operational handover. Evaluate alternative platforms such as Azure Virtual Desktop and VMware Horizon when appropriate.
- Operations and Performance Optimization: Continuously improve logon times, session performance, user experience, and infrastructure resource utilization. Conduct regular platform health checks, review patching strategies, plan technology lifecycle upgrades, and manage end-of-life (EOL) risks.
