hirify.global provides semiconductor solutions that serve as essential building blocks for data infrastructure across enterprise, cloud, and AI architectures.

What you will do

• Own end-to-end verification of PCIe (Gen6/7) and CXL (3.0/4.0) subsystems from test planning through coverage closure and signoff.
• Architect and develop scalable UVM/System Verilog testbenches for PCIe/CXL controllers and fabric-level subsystems.
• Validate CXL.io, CXL.cache, and CXL.mem protocols, including coherency and memory semantics across complex flows.
• Debug complex failures such as protocol violations, ordering issues, and coherency bugs using waveforms, logs, and protocol analyzers.
• Implement System Verilog Assertions (SVA) and drive functional, code, and assertion coverage closure to meet signoff goals.
• Develop Python/Shell automation for regression management, log triage, and coverage reporting.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 5-10 years of experience in ASIC/SoC verification.
• Strong knowledge of PCIe and CXL protocols and architecture.
• Expertise in System Verilog and UVM methodology.
• Experience with debugging complex verification issues and industry-standard simulation/coverage tools.
• Must be eligible to access export-controlled information under U.S. export control laws (EAR).
