Senior Quantum Engineer - Cryo-CMOS Analog Circuit Design

At Microsoft Quantum, we aim to empower science and scientists to solve the world's biggest problems by realizing advanced computing platforms at the intersection of high-performance computing, artificial intelligence (AI), and quantum information technology. For more information about our team, visit https://www.microsoft.com/en-us/quantum.

We are seeking a Senior Quantum Engineer - Cryo-CMOS Analog Circuit Design to design and develop critical analog building blocks for cryogenic control systems used in quantum computing platforms. This role sits within the quantum control team, which develops integrated control electronics that interface directly with quantum devices and enable scalable quantum systems. You will contribute to the design, implementation, and validation of high-performance CMOS circuits operating across room-temperature and cryogenic environments.

This role offers hands-on, multidisciplinary work at the intersection of analog circuit design, system architecture, and experimental validation within a small, collaborative environment. You will play a key role in shaping the technical direction of system development, drawing on system and block design concepts, simulations, experimental insights, program needs, and cross-functional input. Working closely with system architects, digital designers, and experimental physicists, you will translate system-level requirements into robust circuit implementations while driving performance across the control stack-all while contributing individually and empowering others on the team.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities

• Design and develop CMOS analog circuits and functional blocks for quantum control applications
• Contribute to the architecture and specification of Cryo-CMOS subsystems in collaboration with system and hardware teams
• Perform simulation verification of full-custom analog and mixed-signal designs
• Collaborate with cross-functional teams to optimize system-level tradeoffs across analog, digital, and cryogenic domains
• Support bring-up and characterization of ASICs, including integration with system-level control hardware
• Document designs, results, and methodologies to enable reproducibility, knowledge sharing, and downstream integration
• Contribute to technical publications and internal reports as appropriate
• Embody our culture and values.

Qualifications

Required / Minimum Qualifications

• • Bachelor’s degree in Electrical Engineering, Computer Engineering, or related field and proven technical engineering experience

  OR Master’s degree in Electrical Engineering, Computer Engineering, or related field and 4demonstrated technical engineering experience

  OR Doctorate degree in Electrical Engineering, Computer Engineering, or related field and technical engineering experience

  OR equivalent experience

  • Demonstrated industry experience in analog or mixed-signal design delivering complex systems, including experience designing, simulating, and laying out CMOS analog circuits
  • Experience designing analog building blocks such as Analog-to-Digital Converters, Digital-to-Analog Converters, Phase-Locked Loops, and/or Radio Frequency components
  • Experience with cryogenic circuit design, low-temperature measurements, semiconductor behavior at cryogenic temperatures, and/or quantum device interfaces, including hands-on ASIC bring-up, characterization, and lab validation with system-level hardware

Other Requirements:

• Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include, but are not limited to the following specialized security screenings:

  • Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud Background Check upon hire/transfer and every two years thereafter.
  • Citizenship & Citizenship Verification: This role will require access to information that is controlled for export under export control regulations, potentially under the U.S. International Traffic in Arms Regulations (ITAR) or Export Administration Regulations (EAR), the EU Dual Use Regulation, and/or other export control regulations. As a condition of employment, the successful candidate will be required to provide either proof of their country of citizenship or proof of their U.S. permanent residency or other protected status (e.g., under 8 U.S.C. § 1324b(a)(3)) for assessment of eligibility to access the export-controlled information. To meet this legal requirement, and as a condition of employment, the successful candidate’s citizenship will be verified with a valid passport. Lawful permanent residents, refugees, and asylees may verify status using other documents, where applicable.
  • Ability to leverage AI tools to drive innovation and efficiency (e.g., performance modeling and analysis, research gathering, day to day task automation).
  • Ability to work in an “AI-first” environment using modern AI tools to accelerate discovery through hardware development.

Preferred Qualifications

• Deep experience with analog and mixed-signal Electronic Design Automation tools (e.g., Cadence Virtuoso) and proficiency with scripting/programming languages and Linux-based development environments
• Familiarity with digital design and verification languages (e.g., Verilog/SystemVerilog) and signal integrity considerations in high-performance systems
• Proven communication, documentation, and cross-team collaboration skills, with a track record of technical publications or internal reporting and the ability to operate effectively in fast-paced research environments
