Job Description

The Network Engineer is responsible for the engineering, operations, and lifecycle management of a large‑scale enterprise and operational network infrastructure supporting metro and bus transportation services. The role focuses on high‑availability network operations, secure network design, and project execution across a geographically distributed, multi‑vendor environment. This position is designed for a technically strong engineer with a pathway to Network Lead responsibilities.

Technical Scope & Responsibilities

Network Operations & Support Provide L2/L3 operational support for enterprise and transportation networks spanning 100+ remote sites, 2 on‑premise data centers, and approximately 4,000 end users. Maintain network availability for mission‑critical transport operations, including participation in a 24x7 on‑call standby rotation. Perform advanced troubleshooting for routing, switching, wireless, firewall, and WAN issues across complex multi‑domain environments.

Conduct root cause analysis (RCA), implement permanent corrective actions, and support continuous service improvement.

Network Engineering & Project Implementation Design, deploy, and optimize network solutions across: LAN / Campus Networks (VLANs, STP, QoS, wired access) WLAN (controller‑based wireless, secure mobility, high‑density environments) WAN / MPLS (carrier integration, redundancy, traffic engineering) Data Center Networking (core/distribution/access, segmentation, high availability) Participate in network lifecycle activities, including technology refresh, capacity planning, and obsolescence management. Implement resilient and scalable architectures aligned with enterprise and operational requirements.

Security Engineering Configure, operate, and maintain perimeter and internal security controls using Palo Alto and Check Point firewalls. Enforce security policies including network segmentation, access control, and secure routing. Support compliance with ISO standards through secure design, logging, and audit‑ready documentation.
