• Perform firewall sizing, performance tuning, session analysis, and capacity planning for high-throughput environments
• Use Strata Cloud Manager (SCM) for centralized management, templates, device groups, policy management, and operational workflows
• Lead cutovers during maintenance windows, minimizing customer impact and ensuring rapid rollback capability if required
• Follow strong change management processes appropriate to large enterprise or service provider environments
