Tpu Pcie Rtl Design Engineer

Google Google · Big Tech · Sunnyvale, CA +1

This role focuses on the RTL design and verification of PCIe subsystems for Google's next-generation Tensor Processing Units (TPUs), which are custom accelerators for AI/ML workloads. The engineer will architect and implement SoC-level RTL, focusing on foundational infrastructure like clocking, reset, and error handling, and collaborate with hardware and software teams throughout the product lifecycle. The position involves leading PCIe microarchitecture, RTL development, integration, and post-silicon bring-up, requiring expertise in ASIC design, PCIe protocols, and verification methodologies.

What you'd actually do

  1. Lead the PCIe microarchitecture and RTL development, ensuring high-performance designs that strictly adhere to PPA targets, coding standards, and quality guidelines.
  2. Manage the full RTL lifecycle, including documentation and coding, while ensuring the design is sign-off ready for Lint, CDC, and synthesis.
  3. Partner with system architects to integrate the PCIe subsystem, ensuring it meets chip-level bandwidth, latency, and power consumption goals.
  4. Coordinate with Verification and Physical Design teams to develop test plans, leverage PCIe VIP, and achieve successful timing closure.
  5. Resolve complex protocol issues and lead post-silicon bring-up to ensure link integrity and subsystem performance.
