About the role

What will you do at CommandLink?

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.
