Job description

For over four decades, Cirrus Logic has been propelled by the top engineers in mixed‑signal processing. Our rockstar team thrives on solving complex challenges with innovative end‑user solutions for the world's top consumer brands. Cirrus Logic is also known for its award‑winning culture, which was built on a foundation of inclusion and fairness, meaningful community engagement, and delivering enjoyable employee experiences at every turn. But we couldn’t do it without our extraordinary workforce – and that’s where you come in. Join our team and help us continue to make Cirrus Logic an exceptional place to grow your career!

The Role

We’re looking for a high‑caliber engineer with deep expertise in device characterization, test‑chip design, SPICE modeling, and device‑level reliability. In this role, you’ll take ownership of device lab operations, ensuring equipment is optimized and running flawlessly. You’ll perform a broad range of silicon device characterization, extract accurate SPICE and aging models, and help shape the foundation of our next‑generation semiconductor technologies.

If you thrive at the intersection of hands‑on lab work, modeling, and silicon physics, this is your opportunity to make a direct impact on device performance and long‑term reliability.

Required Skills and Qualifications

• Ph.D. in Electrical Engineering, Physics, or a related discipline, or a Master’s degree with 3+ years of relevant experience working in semiconductor device modeling and characterization.
• Strong foundational knowledge of semiconductor device physics, especially as it relates to compact modeling across various device types.
• Proven hands‑on experience performing deep‑submicron CMOS and BCD device measurements, including use of parametric analyzers, LCR meters, and other precision instrumentation.
• Skilled in operating manual, semi‑automatic, and fully automatic probers for device‑level test and characterization.
• Familiarity with both active and passive device structures in CMOS and BCD process technologies.
• Solid understanding of device noise, mismatch behavior, and how these impact circuit‑level performance.
• Knowledge of the physics of device aging and long‑term reliability mechanisms.
• Experience designing test structures (individual devices and arrays) for silicon characterization.
• Demonstrated expertise in SPICE model generation, validation, and QA flows.
• Excellent verbal communication and technical writing skills, with the ability to clearly document results, methodologies, and model behavior.

Preferred Skills and Qualifications

• Ability to stress‑test devices to evaluate post‑stress behavior and safe‑operating‑area (SOA) limits.
• Prior exposure to digital and analog design flows and broader design methodologies.
• Experience running simulations in Cadence ADE.
• Knowledge of test‑structure layout across multiple technology nodes, including advanced CMOS and BCD/HV for analog and mixed‑signal products.
• Strong coding ability in Python, Perl, or similar scripting languages to support analysis and automation.
