Analog Mixed Signal Circuit Design

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:  

·         Architect, design, and simulate analog circuit blocks that comprise the AFE, including:

o   Transmit (TX) circuits: line drivers, pre‑drivers, output stages

o   Receive (RX) circuits: front‑end amplifiers, CTLE, PGA, slicers

o   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.

·         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.

·         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.

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

·         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.

·         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

·   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.

The base salary range for this position is as mentioned below per year. We also provide competitive benefits, incentive compensation, and/or equity for certain roles.
Company benefits include health. dental, and vision insurance. 401(k), and paid leave.
