Network Production Engineer, Physical Network

Meta’s Long-Term Design & Delivery (LTD) team designs the physical infrastructure that carries a rapidly scaling IP and optical backbone. We are looking for a network engineer with solid experience on structured-cabling/physical-infrastructure design to own Inside Plant (ISP) and Outside Plant (OSP) design for Backbone Points of Presence (POPs) and ILA (Inline Amplifier) huts.

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 / network 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

Minimum Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
• 6+ years designing physical infrastructure / fiber-optic infrastructure (OSP and/or ISP) in telecom, backbone/transport, carrier or hyperscale environments
• Strong knowledge of fiber fundamentals: single-mode vs multimode, connector types (LC/MPO), fusion & ribbon splicing, optical-loss / OTDR testing, and optical-budget basics
• Proven ability to turn a network / optical design into a physical build — rack elevations, power requirements, fiber counts, ODF / patch-panel layouts, cable trays / containment, splice plans
• Understanding of IP network hardware platforms and their specifications in the POP and data center space
• Experience producing clear technical documentation and communicating across teams and with vendors to drive cross-functional decisions
• Bachelor's degree in Electrical or Telecommunications Engineering, or a related field, or equivalent practical experience

Preferred Qualifications

• Familiarity with optical line systems / DWDM physical layer and long-haul reach / spans
• Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
• 10+ years designing physical infrastructure in hyperscale environments
• Scripting (Python) for design automation and experience in reading/using topology or GIS/route data
• Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
• Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
