Senior Network Engineer – USAF / Cyber & Networks Directorate
Location: San Antonio, TX (100% Onsite)
Clearance: Active Secret (TS/SCI eligible)
Citizenship: U.S. Citizen Required
Overview
Centurion seeks an expert-level Senior Network Engineer to provide advanced engineering, design authority, troubleshooting leadership, and automation-driven modernization support to the Air Force Life Cycle Management Center (AFLCMC) / Cyber & Networks Directorate. This role requires deep expertise in enterprise network architecture, Cisco ISE, Cisco ACI, datacenter design, virtualization, automation, and secure DoD network operations.
Primary Responsibilities
Identity & Access – Cisco ISE (Expert-Level)
• Architect and maintain Cisco ISE deployments, including Persona roles (Admin, PSN, MnT), redundancy, and distributed deployments.
• Design and optimize 802.1X, EAP-TLS flows, MAB fallback, WebAuth, and wired/wireless NAC strategies.
• Build advanced policy sets, profiling, posture assessments, dACLs, and TrustSec/SGT integrations.
• Lead structured troubleshooting using RADIUS flow analysis, packet captures, Live Logs, debugs, pxGrid, and cross-system correlation.
SDN / Fabric – Cisco ACI (Expert-Level)
• Architect and manage ACI fabrics, including Spine/Leaf topology, APIC operations, and policy-driven object models.
• Design scalable multi-tenant environments (Tenants, VRFs, BDs, EPGs), contracts/filters, micro-segmentation, and preferred groups.
• Lead brownfield-to-ACI migrations, L3Out designs, PBR integrations, and multi-site patterns.
• Use ACI troubleshooting tools such as faults, health scores, atomic counters, endpoint tracking, and operational workflows.
Datacenter Architecture & Operations
• Design and operate modern data center environments, including spine-leaf architectures, ECMP, redundancy tiers, routing layers, and segmented security zones.
• Engineer and troubleshoot SAN/NAS systems, zoning, vPC integration, and datacenter interoperability.
• Develop active-active or multi-site strategies, addressing latency constraints, replication impact, and control-plane separation.
Virtualization Engineering
• Engineer and troubleshoot VMware vSphere, DVS, NIC teaming, uplinks, VLAN/VXLAN, and overlay/underlay MTU alignment.
• Integrate virtual workloads with TOR switches, vPC/LAG behaviors, microsegmentation, and hybrid cloud integrations.
Automation, IaC, and DevOps for Networking
• Build and maintain automated network provisioning using Terraform, Ansible, Python, and Git-based workflows.
• Develop reusable modules, remote state, versioning standards, and continuous integration pipelines.
• Implement validation and rollback procedures as part of end-to-end automation workflows.
Network Architecture, Security, and Operations
• Architect, implement, and optimize enterprise LAN/WAN, wireless (802.11), VPN, MPLS, and site-to-site IPsec networks.
• Engineer routing designs using BGP, OSPF, EIGRP, static routes, and multi-domain network segmentation.
• Enforce Zero Trust, NAC, firewall policies, IDS/IPS, segmentation, and enterprise risk management.
• Perform complex troubleshooting using flow analytics, QoS, SNMPv3, NetFlow, Syslog, packet captures, and advanced diagnostics.
• Operate across DoD network environments and classified network enclaves.
Documentation, Standards, and Operational Continuity (Expert-Level)
• Produce high-quality technical documentation, diagrams, runbooks, and operational guides.
• Maintain documentation lifecycle through Git-based version control, change history, and cross-team enablement.
• Create comprehensive troubleshooting trees, failover procedures, rollback paths, and continuity plans.
Leadership & Collaboration
• Serve as a senior technical advisor to AFLCMC and mission partners.
• Mentor junior and mid-tier engineers.
• Coordinate with cybersecurity, cloud, and mission system teams to support modernization goals.
Required Qualifications
• U.S. Citizen with active Secret clearance (TS/SCI eligibility).
• DoD 8140 IAT Level II (e.g., Security+ CE) or higher.
• Bachelor’s degree + 8+ years experience (or equivalent).
• Expert-level understanding of: OSI Layers 1–4, TCP/IP, enterprise routing/switching, ACI, ISE, VMware, automation.
• Demonstrated ability to design enterprise networks, produce technical diagrams, and lead complex implementations.
Preferred Qualifications
• CCNP, CCIE, or equivalent expert-level certifications.
• Experience in multi-site ACI, TrustSec/SGT architectures, pxGrid, and zero-trust segmentation.
• Experience with DoD classified networks and RMF-compliant architectures.
• Cloud networking experience (AWS, Azure, hybrid models).
