Principal Engineer, Mixed Signal Design Engineering

Analog Devices•Chandler, AZ

About The Position

As a Principal Precision Data Converter Design Engineer, you will serve as a technical authority in the architecture and design of high-resolution analog-to-digital and digital-to-analog converter ICs. You will lead the development of precision data conversion solutions from concept through silicon validation, driving system-level performance across linearity, noise, and dynamic range. Your work will span multiple business units and directly influence ADI’s leadership in precision measurement and data acquisition. You will have full-chip precision converter architecture ownership from specification through silicon bring-up, including noise budgeting and signal integrity analysis spanning analog front-end through digital back-end, and design-for-manufacturing and yield optimization through Monte Carlo analysis and statistical design centering. Reliability assessment including electromigration, hot-carrier injection, and NBTI effects on matching-sensitive structures will also be part of your responsibilities. You will partner with applications, product definition, and systems engineering teams to translate precision measurement requirements into converter specifications, evaluate new process capabilities and identify opportunities for improved matching, lower noise floors, and enhanced converter performance, and contribute to organizational knowledge through design reviews, converter IP development, and cross-team technical forums.

Requirements

MSEE with 10+ years of precision data converter IC design experience, or PhD with 8+ years (BSEE with equivalent depth considered)
Proven expertise in ADC architectures: SAR, delta-sigma, or pipeline, with demonstrated silicon results
Working experience with DAC architectures: current-steering, R-2R, segmented, or charge-redistribution topologies
Deep understanding of precision performance metrics: INL, DNL, SFDR, SNR, ENOB, THD, offset drift, and gain drift
Track record of leading converter designs from concept through tape-out, silicon validation, and production release
Deep understanding of CMOS process technologies, including device matching, noise mechanisms (thermal, flicker, quantization), and layout-dependent effects
Proficiency with Cadence IC design suite: Virtuoso, Spectre/APS, and AMS Designer
Excellent presentation, technical writing, and communication skills

Lead design of precision DAC circuits including current-steering, R-2R, and segmented architectures for high-accuracy output generation
Drive calibration and trimming strategies for offset, gain, and linearity correction across temperature and supply variation
Lead architecture and design reviews, assessing trade-offs across resolution, speed, power, and area
Influence converter IP reuse strategies, design flows, and product roadmaps across multiple programs
