• Qualify new network platforms, optics, and topologies; contribute to architecture and capacity planning
• Build and improve monitoring, alerting, and operational documentation
• Troubleshoot Layer 2/Layer 3 incidents end-to-end
• Automate repetitive network tasks with Python, Ansible, or similar tooling
• Partner with compute, facilities, and software teams during cluster build-outs and maintenance windows
• Support high-performance/supercompute network environments

Basic Qualifications:

• Several years designing and/or operating production networks in a datacenter, ISP, cloud, or large enterprise environment
• Solid hands-on experience with BGP and at least one interior routing protocol
• Working knowledge of TCP/IP, VLANs, EVPN/VXLAN, and optics/high-speed Ethernet
• Experience troubleshooting live production network incidents and participating in on-call
