What you will do

• Own end-to-end verification of PCIe (Gen6/Gen7) and CXL (3.0/4.0) subsystems from test planning to signoff.
• Architect and develop scalable UVM/System Verilog testbenches and integrate PCIe/CXL VIPs.
• Validate CXL.io, CXL.cache, and CXL.mem protocols, including coherency and memory semantics.
• Develop constrained-random and directed test suites to achieve high functional coverage across corner scenarios.
• Debug complex protocol violations, ordering issues, and coherency bugs using waveforms and protocol analyzers.
• Collaborate with design and architecture teams to influence design-for-verification and mentor junior engineers.
