Senior Physical Network Engineer: Backbone Fiber & ISP/OSP

Meta; Nashville (TN); On-site; USD 162,000 - 227,000; Full time

Job summary

Meta’s LTD team designs the physical infrastructure that carries a rapidly scaling IP and optical backbone. We seek a network engineer with strong experience in structured cabling and fiber plant to own Inside Plant (ISP) and Outside Plant (OSP) design for Backbone POPs and ILA huts.

You will translate topology into rack layouts, space and power requirements, cable counts, and BOMs, while collaborating with network engineering, sourcing, and vendors to evolve and scale our network topologies.

Qualifications

• Bachelor's degree in CS, CE, or related field, or equivalent experience.
• 6+ years designing physical/fiber infrastructure (OSP/ISP) in telecom or hyperscale environments.
• Strong fiber fundamentals: single/mode, LC/MPO, fusion/ribbon splicing, OTDR testing, optical-budget basics.
• Ability to translate network designs into physical builds: racks, power, fiber counts, ODF/patch-panel layouts.
• Understanding IP network hardware in POP/data center spaces.
• Experience producing clear technical docs and cross-functional/vendor collaboration.
• Bachelor's degree in Electrical or Telecommunications Eng, or related field, or equivalent experience.

Responsibilities

• Architect, design, engineer and implement scalable physical infrastructure for backbone POPs, self-built ILA sites and midpoints.
• Translate IP and optical topology into physical designs — rack layouts, space and power requirements, power delivery, fiber counts, splice plans, patch schedules.
• 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 and 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.
