About your new role: CommandLink owns and operates its own network infrastructure, we are not a reseller. That distinction matters for this role. As a Senior Network Engineer, you are building and supporting the connectivity layer that underpins our managed network services business: private circuits, carrier interconnects, NNIs, cloud interconnect, and data center presence. This is a service-provider-oriented engineering role, not enterprise LAN support. The right candidate is hands-on, comfortable working directly with carriers and data centers, and knows how to take a connectivity design from paper to production. Key Responsibilities: Design, configure, and support Layer 2 and Layer 3 network services including VLANs, QinQ, NNIs, MPLS, VRFs, BGP, OSPF, static routing, carrier Ethernet handoffs, and point-to-point circuits. Engineer and support carrier interconnects, NNIs, Ethernet transport, wavelength services, dark fiber handoffs, and IP transit from circuit delivery through turn-up testing and troubleshooting. Configure and support private cloud connectivity services including Azure ExpressRoute, covering BGP peering, VLAN tagging, routing policies, redundancy, and bandwidth profiles. Validate physical and logical handoffs during circuit turn-ups, including optics, cabling, MTU, VLAN mapping, BGP sessions, and route exchange. Support data center and colocation deployments including hardware staging, rack installation, cabling, optics, cross-connects, and vendor coordination. Serve as an escalation point for complex connectivity, routing, and transport issues across Layer 1, Layer 2, and Layer 3. Develop and maintain repeatable configuration templates, provisioning runbooks, and troubleshooting documentation. Collaborate with NOC, support, implementation, and sales engineering teams and participate in maintenance windows for network changes and circuit migrations. Takes on additional responsibilities and projects as needed to support the success of the team and organization. What you'll need for success: Hands-on network engineering experience from a service provider, carrier, MSP, ISP, data center, or managed connectivity environment. Strong working knowledge of Layer 2 and Layer 3 networking including VLANs, QinQ, trunks, NNIs, BGP, MPLS, VRFs, routing policy, IP addressing, and carrier Ethernet. Demonstrated experience turning up and troubleshooting carrier circuits, cross-connects, and customer handoffs. Ability to read and produce network diagrams, port maps, IP plans, VLAN assignments, and circuit documentation. Comfortable working directly with carriers, data centers, and vendors through the full circuit lifecycle. Nice to Have Experience with Azure ExpressRoute or similar private cloud interconnect services. Familiarity with MPLS L2VPN/L3VPN, EVPN, VPLS, or carrier Ethernet design patterns. Exposure to dark fiber, wavelength services, or optical transport concepts. Experience with network automation, scripting, or configuration templating. Certifications such as CCNA, CCNP, JNCIA, JNCIP, or MEF. Why you'll love life at Command|Link Join us at CommandLink, where you'll have the opportunity to shape the future of business communication.
