This role will define next-generation switch and rack-scale hardware architectures for hyperscale, cloud and AI data centers-from switch system platforms and rack-level interconnect-and will ensure those platforms meet the bandwidth, power, thermal, reliability and cost targets of large-scale AI fabrics.\nWhat You’ll Do\nLead next-generation data center switch and rack-scale system hardware architecture from concept through product delivery.\nDefine switch platform architectures for:\nData center leaf/spine and top-of-rack switches\nAI scale-up switch systems and rack-level interconnect systems\nHigh-density liquid-cooled rack-scale integrated systems\nAssess the hardware evolution of data center switches, AI server and rack systems; develop 2-3 year technology roadmaps through technology and competitive analysis, identify and select the key next-generation technologies, and establish the justification for new programs.\nDecompose system-level requirements into mechanical, thermal, power, interconnect and manufacturability subsystems; develop system block diagrams, topology and architecture specifications and drive solutions to closure.\nDefine high-speed interconnect architecture including switch chip selection, high-speed PCB channels, connectors, copper cables and optics, in close cooperation with SI/PI teams.\nDefine power architecture for switch systems, covering PSU and power shelf selection, 48V/12V distribution, hot-swap and protection, efficiency and thermal coupling at rack level.\nDefine mechanical and thermal architecture for switch and rack-scale systems, covering air and liquid cooling, serviceability and rack integration, and own the rack-scale platform from design through mass production.\nConduct architecture trade-off studies across bandwidth, radix, latency, power, thermal, density, reliability, serviceability, manufacturability, cost and time-to-market.\nDrive high-availability and RAS architecture, including redundancy, hot swap, fault isolation, recovery, telemetry and serviceability.\nAlign with network architecture and teams to ensure fabric requirements such as lossless Ethernet/RoCE and InfiniBand are reflected in switch hardware design, and work with SI/PI, power, thermal, mechanical, firmware/network OS, validation and software teams to optimize the complete system design.\nBasic Qualifications:\nBachelor’s degree in Electrical Engineering, Electronic Engineering, Telecommunication Engineering, Microelectronics, Computer Engineering, Computer Science or related field.\n10+ years of datacom hardware system development experience, with a proven record of leading router, switch or server system programs.\nDeep expertise in at least one of mechanical structure, thermal or power, with solid working knowledge of the other two, plus demonstrable cases of leading cross-discipline design and manufacturing issue resolution.\nStrong understanding of switch system architecture, including switch ASIC and SerDes, high-speed PCB and interconnect, optics and copper cabling, power and thermal design, plus strong system-level trade-off capability.\nWorking knowledge of Ethernet switching, TCP/IP and network virtualization sufficient to translate fabric requirements into switch hardware requirements, with familiarity of InfiniBand/RoCE loss less network requirements.\nPreferred Qualifications:\nMaster’s degree in Electrical, Computer or Telecommunication Engineering or related field.\nAI data center experience in rack-level scale-up interconnect, high-density liquid-cooled rack systems, or large-scale AI cluster network deployment with InfiniBand/RoCE fabrics, including design and mass production.\nExperience defining a product from 0 to 1, with knowledge of switch silicon and ASIC roadmaps, 800G/1.6T optics, copper cables and connector technologies, and OCP/Open Rack/rack-scale infrastructure standards.\nStrong architecture leadership, communication and executive presentation skills.\nWe are an Equal Opportunity Employer and do not discriminate against any employee or applicant for employment because of race, color, sex, age,
