About the role

Hybrid role blending software and network design focused on long-range IP backbone design, topology planning, and multi-year migration strategies for Meta's backbone across regions, with code-driven automation and cross-functional collaboration.

Responsibilities

  • Own long-term IP backbone design for one or more domains or regions — translating business demand into topology, product definition and device selection 2-3 years ahead
  • Drive new-product introductions: define how and when to introduce them and the migration strategy across existing generations
  • Design and drive large-scale migrations in live environments: MOPs, sequencing, risk assessment, de-risking without outages
  • Own and evolve design rules, standards, and BOMs; drive consensus on simplifications that make designs repeatable and cut delivery churn
  • Deliver a clean product definition and design handoff to delivery/deployment partners
  • Write and review code/automation for the entire design lifecycle: what-if analysis, BOM generation, hardware selection and partner with teams across the entire tooling-ecosystem
  • Partner cross-functionally across Capacity Planning, Network Site sourcing, Network Fiber sourcing and represent designs in XFN reviews and drive decisions through influence
  • Set technical direction for a domain and be the escalation point for complex design/topology problems
  • Collaborate across regions (incl. EMEA/APAC), with flexibility for global-friendly hours, ~10-15% travel expected

Qualifications

  • Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
  • 6 years of experience in designing and/or operating large-scale IP networks
  • Deep TCP/IP, IPv4/IPv6, and BGP (plus MPLS / IS-IS or similar) — configuration, typical patterns, performance tuning
  • Understanding of 400/800G Ethernet and optical transport (DWDM) as it applies to backbone links and long-haul design
  • Experience with network device configuration for at least one vendor (Juniper, Cisco, Arista, etc.)
  • Coding in a higher-level language (Python / C++ / Go)
  • Experience collaborating with cross-functional partners, resolving technical disagreements, and driving alignment across teams without direct authority
