Cryogenic CMOS Analog IC Designer for Quantum Tech

GLOBALFOUNDRIES U.S. INC.; Austin (TX); On-site; USD 85,000 - 202,000; Full time

Job summary

GlobalFoundries is seeking an Analog Design Engineer to develop high-performance analog and mixed-signal CMOS circuits and reusable IP for emerging semiconductor applications, including cryogenic CMOS and quantum systems. You will drive designs from architecture through tapeout and silicon validation, partnering with technology, PDK, modeling, layout, and test teams.

The role requires 5+ years of relevant experience, a strong foundation in CMOS analog design, and proficient use of SPICE, layout

Qualifications

• Bachelor's degree in Electrical Engineering, Microelectronics, Computer Engineering, Applied Physics, or related field.
• Minimum of 5 years of analog or mixed-signal IC design experience.
• Experience taking analog/mixed-signal circuits through schematic design, simulation, layout, DRC/LVS, parasitic extraction, tapeout, and silicon validation.
• Strong knowledge of CMOS analog design fundamentals, device physics, noise, matching, feedback, stability, frequency response, process variation, and PVT/Monte Carlo analysis.
• Proficiency with industry-standard analog IC design, SPICE simulation, layout, physical verification, and post-layout extraction environments.
• Ability to independently analyze complex circuit and silicon performance issues and translate results into design improvements.
• Travel up to 10%.
• Fluency in English (written and verbal).

Responsibilities

• Design and develop high-performance analog and mixed-signal CMOS circuits and reusable IP, including amplifiers, bias and reference circuits, regulators, data converters, oscillators, PLLs, clocking circuits, and drivers.
• Own circuit development from architecture and transistor-level design through simulation, layout supervision, physical verification, tapeout, silicon characterization, and design-to-measurement correlation.
• Perform comprehensive circuit analysis across process, voltage, and temperature, including Monte Carlo/mismatch, noise, stability, linearity, timing, and post-layout parasitic simulations.
• Optimize circuit performance across operating temperature ranges, including cryogenic conditions, power constraints, process variation, device behavior, and layout-dependent effects.
• Collaborate with device modeling and PDK teams to assess model accuracy, identify model or design-rule gaps, and provide circuit-level feedback supporting cryogenic and advanced PDK development and validation.
• Drive analog layout requirements and reviews for device matching, common-centroid structures, shielding, isolation, parasitic management, signal integrity, power integrity, and design for manufacturability.
• Define silicon test structures and characterization plans, analyze measured data, debug performance issues, and correlate hardware results with pre-silicon simulation and compact models.
• Lead technical design reviews, document design methodology and results, mentor engineers, and collaborate with cross-functional internal and external teams to enable customer and technology solutions.
