Physical Network Design Engineer – Backbone & Fiber

Meta; Pierre (SD); On-site; USD 162,000 - 227,000; Full time

Job summary

Meta’s LTD team designs the physical infrastructure that carries our IP and optical backbone. We are seeking a network engineer with experience in structured cabling and ISP/OSP design to own backbone POPs and ILA huts.

You will architect scalable layouts, coordinate with vendors, produce BOMs, and document designs for cross-functional reviews. This role requires hands-on design skills to translate topology into physical builds.

Qualifications

• 6+ years designing physical infrastructure / fiber-optic infrastructure (OSP/ISP) in telecom or hyperscale environments.
• Translate network designs into physical builds — rack elevations, power, fiber counts, ODF/patch panels.
• Produce clear technical documentation and communicate across teams and vendors.
• Collaborate with vendors and cross-functional teams to scale topology.

Responsibilities

• Architect, design, engineer and implement scalable physical infrastructure for backbone POPs, self-built ILA sites and midpoints, including structured cabling and fiber-optic plant: ODFs, fiber trunks, harnesses, ToR/patch panels, raceways and containment, rack layouts, PDUs
• Work closely with our network engineering and sourcing teams to translate IP and optical topology into physical designs — rack layouts, space and power requirements, power delivery, fiber counts, splice plans, patch schedules — within site constraints
• Own high-level site design standards and refresh them as topology and hardware evolve
• Produce the material forecast and BOMs for the manufacturers
• Engage with vendors (e.g., Amphenol, CommScope, Prysmian, Corning) and with ILA shelter manufacturers on components, harness/panel design, quality, and supply to evolve and scale our network topologies
• Produce engineering documentation and represent designs in cross-functional reviews (network engineering, deployment, site acquisition)
• Support design-automation / tooling for BOMs, fiber-plant and rack space modeling where it is useful
• Support and provide guidance to our site sourcing strategy on provider facilities and proposed floor plans against high-level site design standards requirements
• Support and provide guidance to the delivery teams by reviewing low-level site design migration plans
