The ideal candidate is passionate about building world-class verification environments, has deep expertise in protocol verification, and enjoys solving complex architectural challenges.

Key Responsibilities

Technical Leadership

• Lead the verification strategy for complex IPs and SoC subsystems from architecture through silicon.
• Define verification methodologies, reusable verification frameworks, and best practices across multiple programs.
• Drive verification planning, execution, coverage closure, and sign-off.
• Identify verification risks early and proactively drive mitigation plans.
• Lead technical reviews including architecture, RTL, verification, and tape-out readiness reviews.

Design Verification

• Architect and develop scalable UVM/SystemVerilog verification environments.
• Develop constrained-random, coverage-driven verification methodologies.
• Design scoreboards, protocol monitors, checkers, assertions (SVA), and functional coverage models.
• Debug complex RTL, protocol, timing, and integration issues.
• Drive regression planning, automation, and continuous integration improvements.
• Develop reusable VIP and verification infrastructure across multiple product lines.

Protocol Verification

Lead verification efforts involving one or more of:

• Compute Express Link (CXL 2.x / 3.x)
• PCI Express (Gen4/Gen5/Gen6)
• Ethernet (10G–800G)
• AXI, APB, AHB
• High-speed SerDes interfaces
• Memory interfaces including DDR/LPDDR/HBM (preferred)

Cross-Functional Collaboration

• Work closely with Architecture teams to influence design for verification.
• Partner with RTL designers during implementation and debug.
• Collaborate with Firmware, Emulation, FPGA, Post-Silicon Validation, and System Engineering teams.
• Support customer issue analysis and silicon bring-up when required.

Technical Mentorship

• Mentor and coach verification engineers across multiple experience levels.
• Establish verification standards and engineering excellence across the organization.
• Drive innovation in automation, verification productivity, and quality metrics.

Required Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related field.
• Minimum10+ years (Principal) or 15+ years (Senior Principal) of experience in Design Verification.
• Strong expertise in SystemVerilog and UVM.
• Extensive experience in verification planning, execution, and sign-off.
• Deep understanding of constrained-random verification and coverage-driven methodologies.
• Strong experience with assertions (SVA), functional coverage, and protocol compliance.
• Excellent debugging skills involving RTL, simulation, protocol analysis, and waveform debugging.
• Experience with industry-standard simulators such as Synopsys VCS, Cadence Xcelium, or Siemens Questa.

Preferred Technical Expertise

Strong experience in several of the following areas:

• CXL Cache, Memory, and I/O protocols
• PCIe Transaction, Data Link, and Physical Layers
• Ethernet MAC/PCS/PMA architecture
• Coherency protocols
• High-speed interconnects
• AI accelerator connectivity
• Data center SoC architecture
• Multi-chip and chiplet-based systems
• Performance verification
• Low-power verification
• CDC/RDC verification
• Formal Verification
• Portable Stimulus (PSS)
• Python, Perl, Tcl, or similar scripting languages
• Emulation and FPGA prototyping

Leadership Expectations

• Own technical direction for large verification programs.
• Influence architecture and product quality through early engagement.
• Drive cross-functional execution across geographically distributed teams.
• Establish reusable verification IP and methodology.
• Mentor engineers and help grow technical capability within the organization.
• Champion engineering excellence, quality, and continuous improvement.

Preferred Experience

• Experience leading verification for large SoCs or complex connectivity IPs.
• Proven success delivering multiple first-pass silicon programs.
• Experience with AI infrastructure, cloud networking, or hyperscale data center technologies.
• Familiarity with customer-facing debug and post-silicon issue resolution.
• Contributions to verification methodology, reusable frameworks, or industry standards are a strong plus.
