Job Description

Position : Principal / Lead Engineer – PCIe Gen5/Gen6 Controller, PHY & SerDes Integration
Location :San Jose, CA 
Experience :10+ years
 
 
Job Summary
We are seeking a highly experienced Principal/Lead Engineer to drive the architecture, development, integration, and delivery of PCIe Gen5/Gen6 subsystems for next-generation SoCs and chiplet-based products. The candidate will lead PCIe Controller, PHY and SerDes integration activities, contribute to Transaction Layer development, and work closely with Architecture, RTL, Verification, DFT, Physical Design, STA, and Silicon Validation teams.
The ideal candidate should possess deep expertise in PCIe protocol, high-speed interfaces, subsystem integration, timing closure methodologies, and full ASIC development flow from architecture through silicon bring-up.

Key Responsibilities
  • Lead development and integration of PCIe Gen5/Gen6 Controller, PHY, and SerDes subsystems.
  • Define subsystem architecture, interface specifications, microarchitecture, and design documentation.
  • Participate in Transaction Layer development and enhancements.
  • Support PCIe/CXL interoperability and advanced features.
  • Drive integration of high-speed PHY and SerDes IPs.

Work on: 
  • Link training
  • Equalization
  • PLL integration
  • Reference clock architecture
  • PIPE interfaces
  • Lane repair and lane aggregation
  • Collaborate with analog and PHY teams during integration and debug.
Work closely with DV teams to: 
  • Define comprehensive verification plans.
  • Review UVM-based test environments.
  • Develop assertions and coverage metrics.
  • Support protocol compliance testing.
  • Debug simulation, emulation, FPGA, and post-silicon issues.

Support DFT implementation including: 
  • Scan insertion
  • MBIST
  • LBIST
  • JTAG/Boundary Scan
  • At-speed testing
  • Define test requirements for PCIe controller and PHY subsystems.
  • Collaborate with DFT and silicon validation teams to achieve coverage target
  • Develop and maintain subsystem-level SDC constraints for: 
  • Synthesis
  • Static Timing Analysis
  • Place & Route
  • Timing signoff
  • Work with PD and STA teams to achieve timing closure.
  • Silicon Bring-Up & Debug
Support: 
  • PCIe link training debug
  • Compliance testing
  • Silicon characterization
  • Performance tuning
  • Analyze protocol traces and lab debug logs.
