Collaborate with other teams and vendors to address complex issues.
• Documentation and Process Improvement: Develop and maintain clear documentation for networking infrastructure, processes, tools, and workflows to empower teammates to resolve issues via self-service and prevent issue recurrence. Create new documentation for internal use that will serve as our process guides, maintain registries of assets in order.
