Responsibilities

• As a I/O Subsystem Architect, you will own or participate in the following: 
• Architecture development and specification - from early high-level architectural exploration through micro architectural direction and writing a detailed specification
• Memory (PCIe/CXL) and Network (Ethernet) style I/O subsystems, their connection to the internal fabric, RAS and Security requirements, bandwidth and latency targets
• Development, assessment, and refinement of Architecture to target power, performance, area, and timing goals
• Helping produce and review validation plans for functionality and performance

Requirements

• This is an architecture lead position so a senior level of experience is expected.
• Thorough knowledge of I/O Subsystem architecture
• Experience with high bandwidth Ethernet NIC and/or PCIe Ports (and prepared to provide architecture leadership for interfacing to both)
• Experience with Datacenter class RAS, QoS and Security (working with the security team)
• Knowledge of on-chip network protocols: AMBA, AXI, CHI, ACE, Tilelink or APB. 
• Experience with RDMA, RoCEv2, or Infiniband is useful
• Experience with SERDES based PHYs, or Die-to-die (eg UCIe) is useful
• Experience with system-level network topologies such as rings, mesh, torus, fat-trees is useful
• Knowledge of cache coherent memory systems and interconnect is useful
• Knowledge of SystemVerilog or Verilog, C or C++, scripting languages such as Python
• Experience with functional and performance simulators
• Knowledge of logic design principles along with timing and power implications
• Understanding of low power architecture techniques
• Understanding of high performance techniques and trade-offs for I/O

Education and Experience

• Industry experience as well as PhD, Master’s Degree or Bachelor’s Degree in a technical subject area.
