Principal Analog/Mixed‑Signal Engineer

Build the future nobody’s dreamed of yet. As a Principal Analog/Mixed‑Signal Engineer in our Research & Development team, you will merge creativity with technical expertise to shape the future of technology, drive groundbreaking projects, and bring new ideas to life.

Key Responsibilities

Lead the development of high‑performance analog and mixed‑signal ICs from concept through prototype approval and production ramp, including design for manufacturability, yield, test, and reliability.

Act as a key technical interface to customers and internal stakeholders (specification, design, layout, process, test, and product engineering).

Own key technical decisions from architecture through silicon bring‑up, working closely with analog, layout, and digital design teams.

Supervise and perform transistor‑level design, simulation, verification, and validation (PVT, Monte Carlo, mixed‑signal, modeling, optimization) in collaboration with analog, layout, digital design, and validation engineers.

Prepare materials for design reviews and maintain clear internal design documentation, including test requirements and validation plans.

Guide lab and test engineers during measurement and validation of developed analog blocks.

Generate new IP and support patent disclosures/filings,



and mentor junior engineers through project work and technical guidance.

Qualifications

PhD, Master’s, or Diploma in Electrical Engineering or Microelectronics, with an emphasis on analog/mixed‑signal integrated circuit design (or similar).

10+ years of experience in analog and mixed‑signal IC design.

Strong knowledge of Cadence EDA tools and circuit simulation; good knowledge of MATLAB or Python for system/behavioral modeling.

Strong intuitive and analytical understanding of transistor‑level design.

Experience designing most of the following blocks: ADCs, DACs, AFEs.

Experience with an AFE+ADC subsystem is a plus.

Team player with excellent listening, communication, and organizational skills; ability to organize and prioritize work for yourself and others.

Fluency in English; Spanish is an advantage.
