Job description

Responsibilities

We are seeking a highly experienced PCI-Express (PCIe) Validation Expert to lead pre- and post-silicon validation efforts for high-speed storage accelerators. In this role, you will drive end-to-end PCIe validation, ensuring high-performance, standards compliance (PCIe Gen3/Gen4/Gen5 where applicable), and robust interoperability across a wide ecosystem. You will work cross-functionally with architecture, design, firmware, PHY, and system teams to define validation strategies, root-cause complex issues, and deliver high-quality silicon to production. You will focus on:

• Own PCIe validation strategy and execution for the Storage Accelerator products across pre-silicon and post-silicon phases
• Define coverage plans including protocol, link, PHY, power management, and compliance scenarios
• Lead PCIe link bring-up, training, and tuning across multiple generations (Gen3/4/5/6)
• Perform deep debug using protocol analyzers, oscilloscopes, and logic analyzers
• Drive PCI-SIG compliance testing including electrical and protocol validation
• Ensure interoperability with server CPUs from leading manufacturers
• Develop and enhance automation frameworks (Python, C/C++) for validation scalability
• Own and manage Functional Circuit Test (FCT) and In-Circuit Test (ICT) processes
• Lead RMA analysis and work closely with customers and manufacturing teams to resolve board-level issues
• Work closely with Architecture, Design, Software and Signal integrity teams
• Coordinate Test program and test automation scripts development
• Coaching Junior Engineering staff
