Lead Greenfield and Brownfield customer network deployments and production migrations. Design and troubleshoot advanced routing (BGP, OSPF, MPLS, VRF), implement firewalls (FortiGate, Cisco ASA), and build secure enterprise VPN and SD-WAN architectures. Participate in U.S.-aligned change windows and resolve complex escalations to minimize downtime.
This is a remote position.
About the Role
We are hiring a highly technical Senior Network Engineer with strong experience in customer deployments (Greenfield and Brownfield environments).
