Job description

Meta is seeking a Network Hardware Engineer to join the infrastructure team responsible for designing and scaling the physical network systems that power Meta's global data center fleet. In this role, you will drive the development of custom network hardware — including switching platforms, optical interconnects, and high-speed PCB assemblies — that underpin the reliability and performance of Meta's hyperscale infrastructure. You will work at the intersection of electrical engineering and network systems, translating complex network architecture requirements into production-ready hardware designs deployed at massive scale. Participate in the product vision and strategy for data center switches with network engineering, and bring the designs from hardware concept into large-scale production networks Define hardware architecture, including liquid cooling, high-speed SerDes interfaces, optical modules, and management subsystems Lead the electrical design efforts for high-speed PCB layouts, signal integrity analysis, and power delivery networks Collaborate with ASIC, firmware, and network software teams to define hardware-software interfaces and ensure the functional integration of custom silicon into network platforms Drive hardware bring-up, debug, and qualification of prototype network systems in lab environments using oscilloscopes, protocol analyzers, and network test equipment Partner with contract manufacturers and ODMs to translate hardware designs into production-ready network equipment Develop and execute hardware validation plans covering thermal, mechanical, power, and electrical compliance for network infrastructure equipment Document hardware designs, test results, and failure analyses to support cross-functional engineering reviews and manufacturing readiness decisions Bachelor's degree in Electrical Engineering, Computer Engineering, or a relevant technical field, or equivalent practical experience 8+ years of experience in hardware or electrical engineering with a focus on network equipment, data center infrastructure, or high-speed digital systems Experience designing and validating high-speed PCBs for networking applications, including signal integrity analysis for SerDes-based interfaces at 50G, 100G, or higher data rates Experience with hardware bring-up and debug of complex network systems, including use of lab instrumentation such as oscilloscopes, TDRs, and network traffic generators Experience working with ODMs or contract manufacturers through all the hardware development lifecycle stages, including EVT, DVT, and PVT Experience contributing to open networking hardware initiatives or custom silicon-based switching platform development Proficiency in Linux or other embedded environments Background in large-scale data center network infrastructure design, including fabric architectures and disaggregated hardware models Experience working with cross functional engineering teams such as network engineering, software, manufacturing, power, signal integrity and optical teams, discussing architecture and system trade-offs Experience designing systems and boards using high-power ASICs (>500W) and experience with OSFP, or co-packaged optics module integration and characterization
