L4 Network Engineer

Overview

Position : L4 Network Engineer

Location : Westwood, CA (Onsite)

Hiring Mode : 6 Months Contract to Hire

Job Description :

SD-Access and ISE Security are key technologies on top of strong routing protocol experience and Catalyst Center is very helpful.

Summary

We are hiring senior-level network architects (L4 through Principal) to lead design and delivery of multisite Cisco Software Defined Access (SDAccess) solutions at scale. You will set architecture direction, drive complex deployments across distributed campuses, and mentor engineers while partnering closely with security and operations. The ideal candidate holds an active CCIE and demonstrates deep, hands-on expertise across Cisco routing / switching, Cisco Catalyst Center (formerly Cisco DNA Center), Cisco ISE, Cisco FTD firewalls, and Cisco SD – WAN, with expert level command of BGP, EIGRP, OSPF, and related enterprise routing protocols.

What you ll do (Key Responsibilities)

• Own end-to – end SD – Access architecture for large, multi – site enterprises : fabric design (control / edge / border), transit options, segmentation (SGTs / TrustSec), identity policy, and integration with WAN and data center.
• Lead Catalyst Center driven automation : design templates, SDA workflows, network assurance, SWIM, and closedloop operations aligned to reliability / SLOs.
• Design identity- centric security with ISE : policy sets, authorization profiles, posture, PxGrid integrations, wired / wireless 802.1X / MAB, guest / BYOD, and scalable group policies.
• Engineer secure edge and campus perimeters : Cisco FTD / Firepower policy design, NAT, VPN, IDS / IPS, SSL decryption strategy, and high availability.
• Architect SD- WAN underlay / overlay : transport independence, applicationaware routing, DIA / Cloud on – ramp, security integration, and multiregion scale.
• Expert routing at scale : BGP (policy, route reflectors, communities), OSPF, EIGRP, ECMP, redistribution strategies, route filtering, summarization, and IPv6 planning.
• Drive modernization roadmaps : brownfield to SDA migration, hierarchical campus design, QoS, multicast, wireless controller (Catalyst 9800) alignment, and resiliency patterns.
• Deliver hands- on build and escalation leadership : lab validation, pilot, phased rollout, cutover plans, MOPs, change windows, and root – cause analysis for P1 / P2 incidents.
• Mentor and uplift engineering teams : design reviews, standards, runbooks, and enablement sessions for operations and field engineers.
• Stakeholder leadership : collaborate with security, EUC, cloud, and application teams; translate business outcomes into technical architectures and measurable milestones.
• Documentation & governance : HLD / LLD, asbuilts, standards, security exceptions, and compliance artifacts; contribute to reference architectures and reusable templates.
