Note: The job is a remote job and is open to candidates in USA. Red River Technology LLC is seeking a Sr. Network Engineer with expert-level knowledge in enterprise networking infrastructure. The role involves designing, implementing, and troubleshooting complex LAN and WAN solutions, while also mentoring junior engineers and delivering multi-domain network solutions to enterprise customers.
Responsibilities
- 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
Skills
- 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
- 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
- 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
- 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
- Strong time management skills with the ability to manage multiple concurrent customer engagements without sacrificing quality
- U.S. Citizenship 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.)
- MPLS VPN (L3VPN/L2VPN) and carrier interconnect experience 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
- Top Secret clearance preferred or able to obtain desired
