Sr. Network Engineer (Professional Services) - Remote

Join a growing IT Services team that partners with top commercial and federal clients to modernize enterprise networks nationwide. This is a high-visibility role for a networking expert who wants to lead complex, multi-site deployments, mentor rising engineers, and help shape the future of a growing Modern Infrastructure practice.

This position is remote with up to 50% travel to customer sites across the country.

Primary Position Tasks:

- Design, implement, and support complex enterprise LAN and WAN solutions spanning traditional routed/switched infrastructure and modern Software-Defined Networking architectures across multiple vendor platforms.
- Lead SD-WAN deployments including controller/orchestrator onboarding, zero-touch provisioning (ZTP), policy development, traffic segmentation, and QoS configuration (e.g., Cisco Catalyst SD-WAN, Meraki, Palo Alto Prisma, Juniper Session Smart).
- Design and deploy SD-Access or equivalent campus fabric solutions including policy-based segmentation, network access control integration, and intent-based automation (e.g., Cisco SDA with Catalyst Center and ISE).
- Execute WAN circuit migrations and cutovers - including MPLS-to-SD-WAN transitions - and campus LAN modernization projects with minimal customer impact.
- Design and implement SD-Branch solutions that converge WAN connectivity, LAN switching, security, and wireless functions at the branch edge.
- Support, troubleshoot, install, and configure complex enterprise routing, switching, and SDN infrastructure in Cisco-primary and multi-vendor environments.
- Assess, document, and report on enterprise networks to drive LAN/WAN modernization, SDN adoption, and infrastructure refresh initiatives.
- Maintain industry certifications as required to retain strategic OEM partnerships.
- Review and approve new opportunity statements of work (SOWs) and level of effort (LOE) estimates related to the growth of our Modern Infrastructure practice.
- Collaborate closely with design engineering resources when scoping larger LAN, WAN, and SDN-related projects and programs.
- Articulate modern network service capabilities and deployment methodologies - including SDN, cloud networking, and automation in internal and customer-facing capacities.
- Assist pre-sales with customer engagements, technical presentations, and solution demonstrations when applicable.
- Assist in developing, improving, and automating delivery methodologies.
- Other business duties as assigned.

Required Skills

- Must be a US Citizen with the ability to obtain a DoD Top Secret clearance (active clearance is preferred - not required)
- Ability to communicate effectively (written and verbal) with both technical teams and non-technical stakeholders, including executive-level customer contacts.
- Ability to produce professional customer-facing deliverables including HLDs, LLDs, implementation plans, and change control documentation.
- Ability to run projects autonomously or as part of a large engineering team alongside project managers.
- Able to travel up to 50% - able and available to travel via plane and car for extended periods of time, as required by business initiatives.
- 7+ years of related experience in a field or professional services role, with significant focus on enterprise LAN/WAN design and deployment.
- Current professional-level networking certification required (Cisco CCNP Enterprise preferred; JNCIP, ACCP, or NSE7 also considered); CCIE or equivalent expert-level certification strongly preferred. Additional OEM certifications valued (PCNSE, JNCIP, NSE7, ACCP, etc.).
- Deep hands-on expertise with enterprise routing and switching platforms across one or more major vendors (e.g., Cisco Catalyst/ASR/ISR, Juniper EX/MX, Aruba CX, HPE).
- Demonstrated expertise in enterprise WAN design and implementation, including MPLS, DIA, broadband aggregation, and multi-WAN failover architectures. MPLS VPN (L3VPN/L2VPN) and carrier interconnect experience preferred.
- Strong proficiency in enterprise routing protocols: BGP (iBGP/eBGP, route policy, communities), OSPF, and EIGRP across multi-site environments.
- Solid foundation in enterprise LAN technologies: VLANs, STP variants (RSTP/MST), LACP, chassis stacking/virtualization, and campus network design.
- Experience with WAN QoS design and implementation, including traffic classification, marking, queuing, and shaping policies.
- Experience with enterprise network security technologies, including next-generation firewalls (e.g., Cisco Firepower, Palo Alto, Fortinet).
- Hands-on experience with at least one SDN platform spanning WAN, campus LAN, or branch domains is required; deeper, hands-on deployment experience in the following areas is preferred:
- Experience with centralized/cloud network management and intent-based automation/cloud-managed platforms (e.g., Cisco Catalyst Center/DNA Center/Meraki, Juniper Mist/Marvis, Aruba Central) for unified LAN/WAN/wireless visibility and control preferred.
- Experience with WAN observability and synthetic monitoring tools (e.g., Cisco ThousandEyes, IPSLA, NetFlow/sFlow analytics) for path visibility and SLA validation preferred.
- Experience with SASE and cloud-delivered security architectures (e.g., Cisco Umbrella/Secure Access, Palo Alto Prisma Access, Zscaler, Cloudflare One) preferred.
- DMVPN and FlexVPN design and migration experience, particularly in legacy WAN-to-SD-WAN transition engagements, preferred.
- Experience with cloud network connectivity and design (AWS Direct Connect, Azure ExpressRoute, GCP Interconnect) and cloud-integrated SD-WAN deployments preferred.
- Experience with network programmability, automation, and scripting (Python, Ansible, Terraform, NETCONF/RESTCONF, or equivalent) preferred.
Previous Technical Lead, Senior Engineering, or Principal Engineer experience in a VAR or professional services environment preferred.
