About the Job

Requirements

  • At least 10 years of hands-on experience in CMOS mixed-signal integrated circuit design.
  • Expertise in designing high-speed interconnects, Fractional-N synthesizers, PAM4 SerDes above 112 Gbps, equalizers, and multi-phase clock generation.
  • Strong background in analog and digital mixed-signal design, including charge pumps, power control, and other analog building blocks.
  • A Master’s degree (MEng) in Electrical Engineering or a related field is required.
  • Strong communication, leadership, and project management skills.

Responsibilities

  • Design and develop mixed-signal integrated circuits for AI and cloud computing systems.
  • Own the full design cycle, including architecture definition, block-level design, simulation, verification, layout, and evaluation.
  • Drive high-speed interconnect design, including PAM4 SerDes above 112 Gbps in bulk CMOS and FinFET.
  • Design and optimize Fractional-N synthesizers, multi-phase clock generation, and analog building blocks such as charge pumps and power control.
  • Implement and verify high-speed interconnects, equalizers (CTLE, FFE, DFE, and sample/hold), and other key components.
  • Collaborate with cross-functional teams to support timely project execution and design tape-outs.
  • Stay current with mixed-signal integrated circuit design trends and technologies and apply them to improve project outcomes.
  • Travel occasionally to the Bay Area (less than 10%) for the remote position.

Desired Qualifications

  • A Ph.D. in Electrical Engineering, Computer Engineering, or a related field is preferred.
  • Experience with bulk CMOS and FinFET technologies.
  • Ability to drive innovation and implement new design methodologies.
  • Experience in fast-paced environments with a strong track record of delivering high-quality designs on time.
