Location:

Daily onsite presence at our San Jose, CA office / U.S. headquarters in alignment with our Flexible Work policy.

What You’ll Do

• Develop RTL (Verilog/SystemVerilog) for the IO die, integrating UCIe, PCIe, and other high-speed interconnect IP into a cohesive chiplet-based architecture.
• Integrate internal and third-party interconnect IP — UCIe, PCIe, CXL, die-to-die, and NoC — into the IO die, including configuration, glue logic, clock/reset, and interface bridging.
• Modify and customize PCIe and other interconnect IP as needed — controller, PIPE/PHY interface, and configuration logic — to meet die-level requirements and close functional gaps.
• Define and implement die-to-die and chiplet interfaces using UCIe, ensuring protocol compliance and interoperability across chiplets.
• Own the microarchitecture and RTL for IO subsystems such as PCIe/CXL controllers, UCIe adapters, and interconnect fabric bridges.
• Collaborate with verification engineers to develop test plans and debug functional issues at the IP, subsystem, and die level.
• Work with architecture, PHY/SerDes, physical design, and software teams to close requirements across performance, power, area, and interoperability.
• Make design decisions out of a large design trade-off space across performance, power, latency, bandwidth, and cost.
• Develop and automate IP integration and RTL assembly flows using scripting and agentic AI tools and frameworks to improve turnaround time and quality of results.
• Communicate effectively with stakeholders, including users, partners, and management, to ensure that the die is delivered on time and within budget.
• Complete other responsibilities as assigned.
