Configure and optimize dynamic routing protocols (BGP, OSPF, EIGRP, IS-IS) and advanced switching technologies (STP, LACP, VTP, 802.1Q) across complex multi-site topologies.

* Cloud & AI

Infrastructure: Architect and operate Cisco Cloud & AI Infrastructure (CAI) solutions, including data center fabric, AI/ML networking, and high-performance compute connectivity; support integration of AI workload infrastructure into enterprise and hybrid cloud environments.

* MPLS & Transport Services:
Design and deliver MPLS/BGP transport services; manage integrations between service provider and customer environments.

* Network Security:
Enforce security controls including next-generation firewalls, VPNs (IPsec/SSL), ACLs, network segmentation, and Zero Trust architecture; collaborate closely with Cybersecurity teams on policy and compliance.

* Cloud & Hybrid Networking:
Architect and manage SD-WAN, SDN, and NFV solutions; design and support hybrid cloud networking across AWS, Azure, and/or GCP, including connectivity, routing, and security policy enforcement.

* Automation & Infrastructure-as-Code:
Automate network provisioning, configuration management, and validation using Ansible, Python, Terraform, and similar tools; integrate with CI/CD pipelines and infrastructure-as-code workflows.

* Network Access Control:
Deploy and manage NAC technologies (e.g., Cisco ISE) to enforce endpoint compliance and control access to sensitive network segments.

* Network Management & Assurance:
Administer enterprise network management platforms; leverage AI/ML-driven analytics, telemetry, and assurance tooling to proactively monitor performance, identify anomalies, and drive rapid issue resolution.

* Operations & Incident Response:
Serve as the Tier 3/4 escalation point for complex network incidents; conduct root cause analysis, capacity planning, lifecycle management, and performance tuning.

* Documentation & Stakeholder Communication:
Produce and maintain network designs, architecture diagrams, implementation plans, and change management documentation; deliver technical briefings to both technical and non-technical audiences.

* Mentorship & Standards Development:
Mentor junior engineers and contribute to organizational standards, engineering playbooks, and best practices. Requirements:
* BS in Computer Science, Information Technology, Network Engineering, or a related technical field, or equivalent professional experience

* 8+ years of hands-on experience designing, implementing, and operating enterprise-grade IP networks

* Deep expertise in routing protocols (BGP, OSPF, EIGRP, IS-IS) and switching technologies (STP, LACP, VTP, 802.1Q)

* Expertise with Cisco Cloud & AI Infrastructure (CAI), including data center networking, high-performance compute fabrics, and AI/ML workload connectivity

* Proficiency with Cisco platforms across routing, switching, security (ASA/Firepower), and data center product lines; experience with additional vendors (Juniper, Palo Alto, Aruba) a plus

* Experience designing and operating secure network architectures including firewall policy, VPN technologies, ACLs, and network segmentation

* Hands-on experience with SD-WAN/SDN solutions and cloud networking (AWS, Azure, and/or GCP)

* Demonstrated proficiency with network automation tools and scripting (Ansible, Python, or similar) and familiarity with infrastructure-as-code practices

* Experience with NAC platforms (e.g., Cisco ISE, Aruba Clear Pass) and endpoint access control policy enforcement

* Ability to produce technical documentation, network diagrams, and architecture presentations for diverse audiences

* US citizenship and an active TS/SCI with Polygraph security clearance required Desired

Experience:

* Active CCNP, CCIE, JNCIE, or equivalent professional-level network engineering…
