About The Position

The Senior Research Scientist will join Q-CTRL’s Quantum Computing Research team to develop software solutions for calibrating and optimizing quantum dot devices. The role focuses on robust routines for coarse tuning, calibration of high-fidelity single- and two-qubit gates, processor-wide optimization, and maintaining peak performance in real time. The scientist will collaborate with research, product, and engineering teams to turn research insights into usable software tools and production-level solutions.

The position includes performing cryogenic measurements and characterizing quantum dot-based qubits; designing, implementing, and testing control protocols across device bring-up and gate optimization; and developing scalable methods for processor-wide optimization and real-time retuning. The role also involves documenting and presenting research clearly, engaging with researchers at partner organizations about Q-CTRL calibration routines, and driving product development and delivery.

Requirements

• Advanced degree in Physics, Engineering, or a closely related discipline; exceptional candidates with previous industry experience may also be considered.
• At least 3 years of research experience in a relevant field.
• Previous experience in tune-up and characterization of quantum dots.
• Expertise in numerical techniques, statistical learning, and optimization algorithms.
• Good grasp of software development best practices.
• Experience developing software modules for qubit measurement and control using Python, C++, or Rust.

Nice To Haves

• PhD in Physics, Engineering, or a closely related discipline.
• Familiarity with modern AI tools for software.

Responsibilities

• Perform cryogenic measurements and characterization of quantum dot-based qubits.
• Invent, implement, and test control protocols for device bring-up, from coarse tuning through two-qubit gate optimization.
• Develop scalable protocols for processor-wide optimization, including cross-talk mitigation, leakage reduction, defect mitigation, and real-time retuning.
• Collaborate with engineering and product teams to translate ideas and research outcomes into production-level software.
• Explain, document, and present research solutions in accessible language.
• Engage with researchers at partnering companies and organizations to discuss current and future Q-CTRL calibration routines.
• Drive product development and delivery by translating research innovations into practical solutions.
