Architect, design, and implement scalable physical infrastructure for backbone POPs and ILA sites, including fiber-optic plant and rack layouts. Collaborate with network engineering and sourcing teams to translate topology requirements into physical designs while managing vendor relationships and material forecasting.
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)
$162,000/year to $227,000/year + bonus + equity + benefits
