Principal Engineer, ASIC Design Verification

Position: Principal Engineer, ASIC Design Verification Location: San Jose, CA Job Id: 584 # of Openings: 0 Principal Engineer, ASIC Design Verification Location: San Jose (on-site) Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models. Backed by industry giants like NVIDIA, AMD and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures. We are seeking a Principal Design Verification Engineer to lead the verification strategy for our next-generation silicon photonic chip. In this role, you will serve as a technical lead, architecting scalable verification environments and driving high-quality silicon from concept to tape-out. You will look beyond block-level testing to solve complex system-level challenges, define methodologies, and mentor a growing team of bright engineers.

Essential Functions:

• Architect Testbenches: Define and build modular, reusable, and scalable UVM testbench architectures for complex IP blocks and Sub-systems.

• Drive Methodology: Set the standard for verification methodologies, coding guidelines, and coverage metrics. Evaluate and deploy new EDA tools, formal verification techniques, or emulation flows.

• Strategic Planning: Collaborate with Architects and RTL Designers early in the cycle to define the verification plan, identify architectural bottlenecks, and ensure micro-architecture testability.

• Complex Debugging: Lead the effort to debug elusive hardware bugs, root-causing issues across RTL, firmware, and the verification environment.

• Technical Leadership: Mentor senior and junior engineers, conduct code reviews, and foster a culture of engineering excellence.

• Automation & Efficiency: Develop scripts and infrastructure to automate regression testing, performance analysis, and coverage closure. Basic Qualifications:

• Experience: MS in Electrical Engineering, Computer Engineering, or related field with 12+ years of relevant experience in ASIC/SoC verification.

• Core Competency: Expert-level proficiency in SystemVerilog and UVM (Universal Verification Methodology).

• Architecture: Proven track record of building verification environments from scratch (Agents, Scoreboards, Sequencers, etc.).

• Protocols: Deep knowledge of standard interface protocols (PCIe, ARM MCU, AMBA/AXI, UCIe).

• Scripting: Strong proficiency in scripting languages for automation (Python, Perl, Tcl, or Shell).

• Coverage: Experience defining functional coverage groups and driving logic verification to 100% closure. Preferred Qualifications:

• Formal Verification: Experience with formal property checking (VC Formal) and writing SVA (SystemVerilog Assertions).

• Emulation & Acceleration: Hands-on experience with hardware emulation platforms.

• Processor Knowledge: Familiarity with RISC-V or ARM architecture and coherency protocols.

• Mixed Signal: Experience in Analog/Mixed-Signal (AMS) verification.

• Modeling: Experience with C/C++ or SystemC modeling for reference models.

• Experience working on digital designs with multiple clock domains and clock dividers

• Experience in verification of SerDes IP block interfaces in a complex SoC fabric environment

• Experience in verification of the PCS, PMA SerDes layers and internal SerDes digital backends

• Experience with verification of HBM memory interfaces (PHY and controller)

• Experience in formal model equivalence checking tools and verification methodology

• Programming experience in Python Salary range: $190,000 - $240,000 NOTE TO RECRUITERS: Principals only. We are not accepting resumes from recruiters for this position.
