Project Overview
We are seeking an experienced Senior Omnissa Horizon / VMware Horizon Delivery Engineer to support a short-term customer implementation and engineering engagement.
This is a hands-on delivery role, not simply an advisory or architecture position. The selected consultant should be comfortable quickly assessing an existing Horizon environment, identifying issues and gaps, implementing required changes, troubleshooting complex problems, and working directly with our technical team and customer.
The ideal candidate will have strong real-world experience with Omnissa Horizon 8 / VMware Horizon, including Connection Servers, Unified Access Gateway (UAG), Instant Clones, golden images, desktop pools, published applications, App Volumes, Dynamic Environment Manager (DEM), and the supporting VMware infrastructure.
The engineer will also be expected to provide professional documentation and knowledge transfer as part of the engagement.
Scope of Work
Depending on the final customer requirements, responsibilities may include:
Review and assess the existing Omnissa Horizon / VMware Horizon environment.
Gather and validate technical and business requirements.
Review the existing Horizon architecture and identify configuration, performance, security, or operational gaps.
Validate architecture, sizing, redundancy, and deployment approach.
Install, configure, upgrade, or troubleshoot Horizon components.
Configure and validate Horizon Connection Servers.
Configure and troubleshoot Unified Access Gateway (UAG) for secure external access.
Configure and troubleshoot desktop pools.
Build, optimize, and maintain golden images.
Configure and troubleshoot Instant Clone desktop pools.
Configure and support RDSH farms and published applications.
Configure or troubleshoot Omnissa App Volumes.
Configure or troubleshoot Omnissa Dynamic Environment Manager (DEM).
Review user profile, personalization, and application-delivery configurations.
Review and troubleshoot Active Directory, Group Policy, DNS, DHCP, certificates, and authentication dependencies.
Review VMware vSphere dependencies, including ESXi, vCenter, clusters, storage, networking, and resource allocation as they relate to Horizon.
Validate user entitlements, access policies, desktop assignments, and application assignments.
Troubleshoot Horizon Client connectivity and user-session issues.
Troubleshoot Blast Extreme, PCoIP, display protocol, latency, and performance issues.
Assist with SSL certificates, certificate chains, and certificate-related troubleshooting.
Assist with load balancer integration and troubleshooting where applicable.
Identify root causes and provide clear remediation recommendations.
Implement approved configuration changes and remediation activities.
Participate in customer-facing technical meetings and implementation sessions.
Document configurations, changes, findings, and recommendations.
Provide knowledge transfer to our engineering team and the customer.
