Senior Quantum Engineer - Cryo-CMOS Analog Circuit Design

Job Title

Senior Quantum Engineer - Cryo-CMOS Analog Circuit Design

Role Summary

Design and develop analog CMOS circuits and subsystems for cryogenic quantum control electronics. Work on a small cross-functional quantum control team to translate system requirements into robust circuit implementations, support ASIC bring-up and lab validation, and drive system-level performance across analog, digital, and cryogenic domains.

Hands-on, multidisciplinary role combining analog circuit design, system architecture, simulation, and experimental validation.

Experience Level

Senior-level. Typical experience expectations: senior (see Education Requirements for degree-to-experience combinations).

Responsibilities

Primary responsibilities include:

• Design and develop CMOS analog circuits and functional blocks for quantum control applications.
• Define architecture and specifications for Cryo-CMOS subsystems in collaboration with system and hardware teams.
• Perform simulation and verification of full-custom analog and mixed-signal designs.
• Collaborate across analog, digital, and cryogenic domains to optimize system-level tradeoffs.
• Support ASIC bring-up, integration with system-level control hardware, and characterization in lab environments.
• Document designs, results, and methodologies for reproducibility and knowledge transfer.
• Contribute to technical reports and publications as appropriate.

Requirements

Must-have qualifications and conditions:

• Ability to pass Microsoft Cloud Background Check and meet export-control citizenship or residency verification requirements.
• Practical experience with analog/mixed-signal design flows and experimental validation (years depend on degree; see Education Requirements).
• Ability to leverage AI tools for modeling, analysis, research gathering, and task automation.
• Experience working in Linux-based development environments and familiarity with scripting or programming languages.

Nice-to-have:

• Extensive industry experience in analog/mixed-signal design and layout (10+ years preferred) and several years designing, simulating, and laying out CMOS analog circuits.
• Deep experience with EDA tools (e.g., Cadence Virtuoso) and verification flows.
• Experience designing ADCs, DACs, PLLs, RF components, and attention to signal integrity in high-performance systems.
• Familiarity with digital design/verification languages (Verilog/SystemVerilog).
• Experience with cryogenic circuit design, low-temperature semiconductor behavior, quantum device interfaces, and hands-on ASIC bring-up and lab characterization.
• Strong communication, documentation, and cross-team collaboration skills; track record of publications or internal reporting.

Education Requirements

One of the following: Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field plus 6+ years technical engineering experience; OR Master's degree in Electrical Engineering, Computer Engineering, or a related field plus 4+ years technical engineering experience; OR Doctorate degree in Electrical Engineering, Computer Engineering, or a related field plus 1+ years technical engineering experience; OR equivalent practical experience.
