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.
