Senior PCIe/CXL RTL Design Engineer

Job Title

Senior PCIe/CXL RTL Design Engineer

Role Summary

Design and deliver RTL for high-performance PCIe and CXL interfaces. Work with architecture, verification, synthesis, and layout teams to implement reliable, synthesizable logic for host and device datapaths and control functions.

The role operates on an ASIC/SoC team focused on high-speed I/O controllers; responsibilities include RTL development, functional and timing closure support, and cross-team integration.

Experience Level

Senior-level; years of experience not specified.

Responsibilities

The core responsibilities include specification implementation, RTL development, and cross-team collaboration:

• Develop and maintain RTL (typically SystemVerilog) for PCIe and CXL protocol blocks.
• Translate protocol and microarchitecture specifications into synthesizable RTL.
• Create and run simulations to verify functionality; debug failures and close functional issues.
• Work with synthesis and timing teams to meet area, power, and timing targets; support timing closure activities.
• Collaborate with verification, firmware, and physical design teams during bring-up and integration.
• Support silicon bring-up and debug as needed (root-cause analysis, instrumentation, lab validation).

Requirements

Concise list of required and preferred qualifications.

• Must-have: Practical experience designing RTL for PCIe and/or CXL controllers and interfaces.
• Must-have: Strong RTL coding skills in SystemVerilog and experience with simulation tools and flows.
• Must-have: Experience with synthesis, timing closure concepts, and static timing analysis.
• Must-have: Debug skills for simulation and silicon-level bring-up; ability to work cross-functionally.
• Nice-to-have: Experience with UVM-based verification environments, FPGA prototyping, scripting (Python/Perl/Tcl), and familiarity with CXL protocol specifics.

Education Requirements

Not specified.
