We are on the cusp of an accelerated effort in quantum computing. This position offers an opportunity to have a meaningful influence on a revolutionary technology. For more information about the Microsoft Quantum team, please visit https://quantum.microsoft.com/. We are seeking a Principal Quantum Systems Architect to define the architecture of scalable classical control and readout systems for large-scale quantum computing. This role focuses on system design at the quantum-classical interface, including compute platforms and communication fabrics. This is a strategic technical leadership role, shaping long-term architecture while guiding validation and integration across the stack. 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 • Define the system architecture for scalable quantum control and readout • Drive architectural direction for heterogeneous compute platforms supporting control, measurement, and feedback workloads • Establish system partitioning and co-design strategies across hardware, firmware, microarchitecture, software, and quantum systems • Lead the collaboration with third-party quantum hardware partners in Europe • Lead system-level trade-offs and guide platform evolution toward scalable, production-ready quantum systems Other: • Embody our Culture and Values Qualifications Required Qualifications: • Doctorate in Physics, Engineering, or related field AND experience in industry or in a research and development environmentOR Master's Degree in Physics, Engineering, or related field AND experience in industry or in a research and development environmentOR Bachelor's Degree in Physics, Engineering, or related field AND experience in industry or in a research and development environmentOR equivalent experience.Experience driving architectural trade-offs across performance, scalability, power, and reliability 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. • Familiarity with basic AI tools such as Office CoPilot, GitHub CoPilot, or Chat GPT. • Ability to work in an “AI-first” environment using modern AI tools to accelerate discovery through both hardware and software development. Preferred Qualifications: • Proven experience designing complex compute or signal-processing architectures (e.g., SoCs, distributed systems, accelerators, networking fabrics) • Proficient understanding of system architecture fundamentals (compute, memory, interconnects, data movement, HW/SW partitioning) • Demonstrated leadership in cross-functional hardware/software co-design initiatives • Familiarity with quantum control, readout, or error correction concepts • Experience with FPGA, ASIC, or custom accelerator technologies • Exposure to cryogenic or constrained computing environments • Experience defining scalable architectures for emerging compute platforms #Quantum #QuantumCareers #MDQCareers Quantum Software Engineering IC5 - The typical base pay range for this role across Switzerland is CHF 183,800.00 - CHF 309,700.00 per year.
