- Troubleshooting Under Pressure: Rapidly diagnose and resolve network outages or performance degradation in a high-risk environment. You must be able to maintain composure and follow strict Change Management protocols while under pressure.
- Virtualization Integration: Collaborate with the broader IT team to manage network connectivity for our Virtualization infrastructure (VMware/vSAN), ensuring high-speed, redundant paths for server traffic.
- Documentation: Maintain precise network diagrams, IP schemes, and cable maps for both the enterprise and BMS networks.
