We are seeking a Senior Quantum Engineer – System Characterization to characterize and validate cryogenic control hardware used in our quantum computing systems. This role focuses on system‑level performance characterization, bridging cryogenic electronics and quantum device measurements. Working within the cryogenic complementary metal‑oxide semiconductor (cryo‑CMOS) team, you will have the opportunity to make a significant impact on a revolutionary technology. We are looking for an experimentalist with substantial experience measuring semiconductor qubit and/or quantum dot devices with a strong passion for interdisciplinary collaboration.
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.

Requirements

• Bachelor’s Degree in Physics, Engineering, or related field AND 6+ years experience in industry or in a research and development environment.
• OR Master’s Degree in Physics, Engineering, or related field AND 4+ years experience in industry or in a research and development environment.
• OR Doctorate in Physics, Engineering, or related field AND 1+ years experience in industry or in a research and development environment (which may include completion of a post‑doctoral research position).
• OR equivalent experience.
• 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 or Export Administration Regulations, 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 work in an “AI-first” environment using modern AI tools to accelerate discovery through both hardware and software development.
• Ability to design and build AI agents/copilots that assist with experiment setup, log triage, measurement report generation, protocol templating, and knowledge retrieval (e.g. instrument manuals, design docs).

Nice To Haves

• Doctorate in Physics, Engineering, or related field.
• 6+ years of experience with:
• Low‑noise electronic measurements (e.g., lock‑in amplifiers, analog preamps).
• Cryogenic techniques (e.g., Helium 3 cryostats or dilution refrigerators).
• Electrical transport characterization (semiconductors, dielectrics, superconductors).
• Radio frequency (RF) or microwave measurement techniques.
• Data acquisition and programming in a high‑level language (e.g., Python).
• 4+ years of experience with quantum measurement of semiconductor qubit or quantum dot devices.
• Experience with analog electronic circuit design.
• Experience with technical report writing and documentation.
• Experience with cross‑team collaboration and/or mentoring.

Responsibilities

• Characterize the performance of integrated cryogenic ASIC‑based control systems interfacing with quantum devices.
• Design, execute, and analyze measurement campaigns to evaluate cryogenic control hardware and system behavior.
• Develop and refine measurement techniques to assess device‑level and system‑level performance.
• Collaborate closely with multidisciplinary partners—including ASIC designers, electrical engineers, qubit measurement engineers, and theorists—to inform and optimize system design.
• Analyze, document, and communicate characterization results, limitations, and findings to hardware and system development teams.
• Verify that the integrated cryogenic control system meets defined performance requirements and specifications.
• Embody our Culture and Values
