Principal Mixed-Signal Design Engineer

Job Title

Principal Mixed-Signal Design Engineer

Role Summary

Lead development of high-speed mixed-signal data converters in the Advanced Cores Group, focusing on architecture selection, transistor-level circuit design, and integration into SoC products. Work is performed in a hybrid model based in Durham, NC.

The role supports applications across communications, automotive, aerospace/defense, and instrumentation.

Experience Level

Senior — requires 14+ years of CMOS design experience.

Responsibilities

The principal engineer will:

• Lead circuit development and evaluate/select converter architectures.
• Design transistor-level circuits for ADCs, DACs, and associated analog blocks.
• Prepare design documentation and lead technical design reviews.
• Coordinate and guide layout, evaluation, and test engineering teams through tapeout and characterization.
• Mentor and develop other design engineers and provide technical leadership on projects.

Requirements

Key qualifications and skills required:

• 14+ years of practical CMOS design experience.
• Proven experience in high-speed data converter design (pipeline ADC, SAR ADC, current-steering DAC).
• Deep knowledge of analog circuits: wide-bandwidth amplifiers, comparators, switched-capacitor circuits, precision voltage/current references, and LDOs.
• Proficiency with Cadence schematic capture and SPICE simulation tools.
• Experience using MATLAB for behavioral modeling.
• Strong written and verbal communication skills and ability to work effectively in large teams.
• Demonstrated ability to take technical ownership and solve complex circuit challenges.

Nice-to-have:

• Signal processing knowledge, especially calibration algorithms.
• Experience with FinFET process technologies and SoC integration.

Note: Applicants who are not U.S. citizens, U.S. permanent residents, or other protected individuals may require export licensing review.

Education Requirements

Required: M.S. or beyond in Electrical Engineering. Advanced degrees (MS/PhD) are explicitly specified.
