Quantum Systems Software Engineer II

Microsoft Microsoft · Big Tech · Redmond, WA +1 · Quantum Engineering

Software Development Engineer II role focused on building software tools and systems for operating quantum computers, involving configuration, calibration, monitoring, and control. The role requires strong software engineering fundamentals and collaboration with physicists and hardware engineers.

What you'd actually do

  1. Design, implement, and maintain software tools and applications that support configuration, control, and operation of quantum hardware systems.
  2. Develop high‑quality, well‑factored software in Python and system languages such as C, C++, C#, or Rust.
  3. Build and maintain user‑facing applications and tooling using Qt to enable efficient workflows for quantum hardware development and operations.
  4. Apply solid software engineering fundamentals, including object‑oriented design, modular architectures, and maintainable codebases.
  5. Write robust unit, integration, and system tests to ensure correctness and reliability of critical tooling.

Skills

Required

  • Master's Degree in Physics, Engineering, or related field OR Bachelor's Degree in Physics, Engineering, or related field AND 2+ years experience in industry or in a research and development environment OR equivalent experience.
  • Ability to meet Microsoft, customer, and/or government security screening requirements
  • 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

Nice to have

  • Proficient understanding of software engineering fundamentals, including object‑oriented design, proper software factoring, and maintainable system design.
  • Experience designing and writing automated tests and debugging non‑trivial software systems.
  • Familiarity with Git and modern development workflows.
  • Proficient written and verbal communication skills.
  • Experience developing desktop or system tooling using Qt.
  • Experience working on hardware‑adjacent software, instrumentation control, or systems that interact with physical devices.
  • Familiarity with scientific or experimental software environments.
  • Exposure to performance‑sensitive systems or long‑running services.
  • Interest in quantum computing, advanced hardware systems, or large‑scale experimental platforms.
  • 2+ years programming experience in Python and at least one system programming language (e.g., C, C++, C#, Rust).
  • 1+ year(s) experience working in a collaborative, team‑based software development environment.

What the JD emphasized

  • Ability to meet Microsoft, customer, and/or government security screening requirements are required for this role.
  • 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.
