Principal / Senior Principal Design Verification Engineer – CXL / PCIe / Ethernet:

Role Overview

We are seeking an experienced Principal / Senior Principal Design Verification Engineer to lead the verification of next-generation connectivity IPs and SoCs powering AI and cloud infrastructure. This is a highly visible technical leadership role where you will define verification strategies, drive methodology improvements, mentor engineering teams, and collaborate across architecture, RTL, firmware, validation, and silicon teams to ensure first-pass silicon success.

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/System Verilog 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 System Verilog 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.
