Analog Mixed Signal Circuit Design

About the role

Job Title: Principal/Sr Principal Circuit Designer - Analog / SERDES (Automotive Transceivers)

Location: This position is located in San Jose, CA. This is a hybrid role with 3 days in office and 2 days work from home. This role is NOT open to 100% remote.

Role Summary

Seeking a Principal or Senior Principal Circuit Designer to design and deliver high-speed, high-linearity analog and SERDES circuit blocks that form the Analog Front End (AFE) of automotive transceivers.

This is a hands-on individual contributor role requiring deep expertise in TX, RX, and clocking circuit design for high-speed PHYs. The role focuses on block-level ownership, from specification and transistor-level design through silicon validation and production support. At the Senior Principal level, the role also provides technical leadership across projects, influencing architecture and mentoring other designers.

Job Responsibility: Analog / SERDES Circuit Design

• Architect, design, and simulate analog circuit blocks that comprise the AFE, including:
• Transmit (TX) circuits: line drivers, pre-drivers, output stages
• Receive (RX) circuits: front-end amplifiers, CTLE, PGA, slicers
• Clocking circuits: PLLs, DLLs, clock distribution, jitter filtering
• Translate system- and PHY-level requirements into robust block-level specifications.
• Optimize designs for linearity, noise, jitter, power, area, and robustness.
• Perform detailed transistor-level simulations across PVT corners and full automotive temperature ranges.

Silicon Bring-Up, Debug & Production Support

• Support silicon bring-up, characterization, and validation of analog/SERDES blocks.
• Correlate simulation results with silicon measurements and drive design improvements.
• Collaborate with layout, digital, DSP, systems, test, and product engineering teams.
• Drive resolution of performance, yield, and reliability issues through root-cause analysis.

Technical Leadership (Principal / Sr Principal Scope)

• Serve as block-level technical owner for critical analog/SERDES functions.
• Participate in and lead technical design reviews.
• Influence AFE and PHY architecture decisions through deep technical expertise.
• Mentor senior and mid-level designers and contribute to design best practices.

Job Qualification

Education

• MSEE or PhD in Electrical Engineering or equivalent (strongly preferred).

Experience

• 12-15+ years of experience in analog or mixed-signal IC design (Principal).
• 15-20+ years of experience for Senior Principal level.
• Proven hands-on experience designing high-speed SERDES or wireline analog circuits.
• Demonstrated success delivering TX, RX, and clocking circuits to production silicon.
• Extensive experience with circuit design, simulation, and debug at the transistor level.

Examples of Core Technical Expertise

• High-speed TX and RX circuit design
• Linearity, distortion, and noise analysis
• Jitter generation, tolerance, and clock integrity
• PLL / DLL and clocking architectures
• PVT variation and automotive robustness
• Advanced CMOS processes for high-speed analog

Highly Desired Experience

• Direct experience with one or more of the following:
• 10GBASE-T
• 10GBASE-T1 (Automotive Ethernet)
• TDD-based transceivers
• Familiarity with automotive semiconductor requirements (AEC-Q100, temperature, EMI/EMC).
• Experience supporting automotive production ramp and customer qualification.
• Exposure to ISO 26262 / functional safety concepts is a plus.
