Principal PCIe Subsystem RTL lead

We are looking for a Principal PCIe Sub-system Front-end RTL lead for next generation chiplet based SoCs for High-performance Compute and AI silicon .

• Own the PCIe subsystem microarchitecture from the PHY interface through the MAC and Transaction Layer, defining the internal block boundaries, data paths, and control interfaces.
• Lead the integration of third‑party PCIe controller and PHY hard IP, including wrapper RTL that adds mode selection, telemetry hooks, and bridging logic to the chiplet's internal fabric.
• Define and implement the bifurcation and lane-configuration logic, ensuring all supported lane-width configurations operate correctly across the full range of operating modes.
• Specify and drive implementation of the Transaction Layer pipeline: TLP reception, integrity checking, header classification, routing decisions, and handoff to downstream subsystems.
• Own the Virtual Channel and flow‑control architecture, ensuring fair arbitration and back‑pressure handling across all traffic classes.
• Define the integration interface to the PCIe subsystem such asTLP-to-flit adaptation, flow‑control mapping, and error handling at the boundary.
• Collaborate with the management firmware team to define the PCIe register map, mode‑select interface, and run‑time telemetry structures exposed to the on‑chip management processor.
• Work with the Physical Design Lead to meet timing closure requirements for the PCIe subsystem, including MAC‑PHY interface timing, reset sequencing, and floorplan constraints.
• Hold the PCIe performance budget for each operating mode: bandwidth efficiency, latency through the Transaction Layer, and error recovery overhead.
• Define the PCIe power management architecture — link state transitions, ASPM policy, and integration with the chiplet‑level power coordination scheme.
• Lead PCIe silicon bring‑up planning: define bringup sequence, debug instrumentation requirements, loopback modes, and the hand‑off criteria for production readiness.
• Mentor and guide RTL design engineers responsible for PCIe subsystem implementation, providing architectural guidance and RTL review.
• Partner with the DV team to define the PCIe UVM verification plan, coverage model, and protocol‑checker requirements.
• Serve as the technical point of contact for PCIe‑related customer integration questions, supporting anchor customer engagements on interface bring‑up and interoperability.
• Author and maintain the PCIe subsystem micro‑architecture specification, keeping it current through RTL implementation and sign‑off.

• 10+ years of digital IC design experience, with at least 4 years focused on PCIe subsystem design or integration at the block‑lead or module‑owner level.
• Deep expertise in PCIe architecture:
  Transaction Layer, Data Link Layer, Physical Layer, TLP structure, flow control, Virtual Channels, and error handling.
• Hands‑on experience integrating PCIe hard IP (controller and/or Ser Des PHY) into production SoC or chiplet designs, including wrapper RTL, reset sequencing, and PnR constraints.
• Background in SR‑IOV, multi‑function device configuration, or host software driver interaction at the hardware level.
• Strong System Verilog RTL skills: able to write, review, and own production RTL for complex pipelined state machines, FIFOs, arbiters, and control logic.
• CXL 1.1/2.0 or 3.0 protocol knowledge, particularly CXL.io and CXL.mem transaction handling built on the PCIe fabric.
• Solid understanding of PCIe PHY‑MAC interface protocols and timing requirements,
• Experience with PCIe compliance testing and PCI‑SIG certification process — understanding of test requirements, common failure modes, and debug methodology.
• Familiarity with PCIe power management, L0s/L1 state machines, state transitions etc.
