About The Position

We are seeking a CCIE Route & Switch–caliber Senior Network Engineer for a 3 - 4 month, full-time contract to serve as a senior technical authority and individual contributor focused on network design, implementation, and complex problem resolution. This role is ideal for an engineer who operates at the expert protocol level, leads through technical depth and execution excellence, and is trusted to design and deploy highly resilient enterprise and data center networks within a defined engagement period. This position is deeply hands-on, with primary ownership of routing and switching architecture, implementation, and lifecycle improvements across enterprise, data center, and hybrid cloud environments in the Orange County, California. The ideal candidate is a design-and-implementation-focused network engineer with mastery of routing and switching fundamentals and advanced architectures. You will take ownership of large-scale network initiatives end-to-end, from requirements gathering and design through implementation, validation, and operational handoff during a time-bound 3–4 month engagement. This role requires CCIE certification (or demonstrably equivalent experience), strong protocol-level knowledge, and the ability to translate business and security requirements into clear, buildable, and supportable network designs. You will serve as a senior escalation point and technical mentor, helping establish engineering standards, reference designs, and best practices while remaining directly involved in implementation and troubleshooting. This is not a management role. It is a short-term, senior, hands-on engineering engagement for a CCIE-level network engineer who wants to remain focused on designing and implementing complex networks rather than managing people or budgets. You will be trusted to: Own complex routing and switching designs from concept to production Implement solutions that become long-term architectural standards Solve the hardest network problems in the environment

Responsibilities

Design and implement enterprise, data center, and disaster recovery network solutions
Architect, deploy, and maintain highly available, fault-tolerant, and scalable routing and switching environments
Own routing and switching design and implementation, including BGP, OSPF, ECMP, segmentation, and control-plane protection
Perform expert-level troubleshooting for complex, multi-domain network issues using packet captures and protocol analysis
Design and implement data center, MDF/IDF, and access-layer network architectures, including segmentation and end-to-end deployment
Produce and maintain HLDs, LLDs, and implementation documentation for current and future-state designs
Execute technology evaluations, proofs of concept, and lab testing to validate design assumptions and operational impact
Collaborate with security, infrastructure, and cloud teams to ensure cohesive and secure network implementations
Contribute to network monitoring, telemetry, and self-healing designs to improve stability and mean time to resolution
Mentor mid- and senior-level engineers on routing, switching, and troubleshooting best practices
Ensure implementations align with security and compliance requirements, including NIST 800-53 where applicable
