Network Field Engineer

NETWORK ENGINEER MERGER & ACQUISITION NETWORK INTEGRATION Location Approximately up to 50% onsite at corporate HQ, Houston, Texas Travel Approximately up to 50% to company locations, offices, data centers, and field sites, including yards, shops, and construction or utility sites Hours Cutover and maintenance work frequently falls in evening and weekend windows NETWORK ENGINEER POSITION SUMMARY We are seeking a Network Engineer to support its Merger and Acquisition (M&A) program.

This is a hands-on role for an engineer who works directly in network devices — assessing acquired environments, building and configuring standard equipment, executing site cutovers, and troubleshooting through to resolution. The work is project-based and spans the full delivery lifecycle — discovery, documentation, bill of materials, procurement support, step-by-step implementation planning, and execution. The engineer produces the plan and then carries it out.

NETWORK ENGINEER RESPONSIBILITIES Discovery, documentation, and planning Perform discovery and validation at acquired sites — circuits, IP addressing, routing, switching, wireless, firewalls, network access control, remote access, and dependencies — establishing ground truth by inspection rather than relying on existing documentation. Assess current state, identify architectural risks, and contribute to target-state design and per site integration plans. Build site bills of materials — switches, access points, edge routers, optics, licensing, PoE and power, racks, cabling, and spares — and support procurement on part selection, entitlements, and lead times.

Write step-by-step implementation and cutover plans with pre-checks, sequenced steps, validation, go / no-go criteria, and per site rollback. Track new job site and branch office builds through 's service management system, following the process applicable to each request type. Maintain accurate diagrams, configurations, procedures, and as found and as built documentation. Implementation and cutover Stage, install, and configure standard network, security, and wireless equipment;

rack, cable, label, and commission at acquired offices, yards, shops, and data center spaces. Replace acquired switching and wireless with standard equipment. Execute site cutovers and circuit migrations in approved change windows, coordinated with the acquired company's change control process. Coordinate with M&A project teams, infrastructure and security teams, local IT contacts, carriers, vendors, and field technicians. Troubleshoot issues arising from integration work using logs, packet captures, and device output to identify root cause;

escalate high-impact issues while continuing to drive resolution, keeping stakeholders clearly updated. Transition support Support the acquired company's existing network platforms through the transition period. These vary by acquisition and commonly include Fortinet, Meraki, and Palo Alto. Where elements of the acquired environment remain in service during transition — typically the WAN and a firewall supporting their legacy VPN — maintain them and make routing changes as sites migrate.

Maintain connectivity between and the acquired environment throughout a phased, multi-site cutover. Identify and resolve overlapping IP space between the acquired environment and , and account for the DNS consequences of the approach chosen — re-IP of DNS servers at headquarters and main branch sites carries significant downstream impact.
