Senior Horizon Engineer

Requirements

• A senior, hands-on Horizon engineer with 7+ years of real production experience
• Comfortable taking ownership of both technical outcomes and operational quality
• Experienced in applying automation and infrastructure-as-code thinking to improve reliability and consistency (even if not everything is fully codified)
• Data-driven in how you troubleshoot, optimize and justify changes
• Execution-focused, with a strong bias toward fixing root causes rather than symptoms
• Calm and methodical under pressure, especially during incidents
• Clear communicator who can explain technical decisions using evidence and impact

What you'll be doing

• Operate and support production VMware Horizon (Omnissa) environments
• Own and execute Horizon platform upgrades (agents, pods, components) with minimal user impact
• Troubleshoot and remediate performance, stability, and user-experience issues using metrics and evidence, not guesswork
• Diagnose and resolve authentication and login-related issues (AD, GPOs, certificates, SSO, MFA integrations)
• Design and implement repeatable processes using PowerShell-first automation, APIs, and infrastructure-as-code principles where applicable
• Use monitoring and operational data to drive capacity planning, tuning, and remediation decisions
• Work closely with infrastructure, networking, and security teams on cross-domain issues and improvements
• Analyze and address resource contention across compute, memory, storage, network, and vGPU where applicable
• Participate in remediation initiatives related to performance degradation, login latency, session instability, and user-impacting incidents
• Continuously reduce manual operational effort through scripting, standardization, and platform improvements
