Founded in 2017, Q-CTRL has grown to become the global leader in quantum. We're using control to solve the hardest problems facing quantum technology, improving hardware performance and accelerating pathways to useful quantum computers and other technologies. As a product-led company, we bring together diverse teams such as product, design, engineering and research to help achieve our mission of making quantum technology useful. Join us to help shape the quantum future. As one of the fastest growing companies in the quantum sector, we've had a number of key milestones: In November 2023, we announced an industry-first partnership with IBM Quantum Services, natively integrating our performance management software with all IBM quantum computers. Building off of this relationship, in September 2024 we started offering two services via IBM's new Qiskit Functions Catalog as an inaugural partner. Designed and moved our Global HQ offices and lab space into the first purpose-built (and award winning) commercial and research facility for a quantum technology company in Australia. Continued to deliver real world outcomes across the quantum sectors, with our work with Australian Defence on software-ruggedized quantum sensing for navigation without GPS, as featured in the New York Times. In October 2024, we announced our record breaking expansion of our Series B funding round to USD $113M, with $59M USD of new capital. Grew our global presence to include Los Angeles, Berlin, and Oxford - as well as the recently announced office in San Francisco. From educating the workforce on how quantum computing works, to building the next generation of quantum sensors, to delivering massive performance gains for end-users, it all starts with hiring the right talent.

  • Working with the team and the department head on establishing strategic research roadmap and OKRs.
  • Perform cryogenic measurements and characterization of quantum dot-based qubits.
  • Invent, implement and test novel control protocols for all the required bring-up steps starting from coarse tuning to optimizing two-qubit gates.
  • Oversee development of scalable protocols for processor-wide optimization (e.g. cross-talk mitigation, leakage reduction, defects mitigation), and real-time retuning.
  • Collaborating with the product manager and engineering team manager to ensure timely deliverables for the Boulder Opal product.
  • Explain, document and present research solutions in accessible language.
  • An advanced degree in Physics, Engineering, or a closely related discipline. A PhD is preferred, but we also consider exceptional candidates with previous industry experience.
  • 3 years of experience (beyond PhD) in tune-up and characterization of quantum dots.
  • Expertise in numerical techniques, statistical learning, and optimization algorithms.
  • A good grasp of software development best practices, and experience in developing software modules for qubit measurement and control (Python, C++, Rust).
  • Flexibility: We embrace workplace flexibility so you worry more about your impact vs a rigid work schedule.
  • Attractive salary: You'll get to have the start-up impact without the start-up wages.
  • Equity: We want people to have a sense of ownership in what they do and offer the potential for equity share and annual bonuses.
  • Cash bonus: We recognize exceptional performance and impact by offering annual discretionary cash bonuses.
  • Resources: We are well funded by the world's best technology investors, letting us chase our ambitions with minimal constraints.
  • Parental support: We offer paid parental leave to support you and your loved ones.
  • Diversity: We're an equal opportunity employer and actively support initiatives like the 'Global Women in Quantum' program to help expand the quantum workforce.
  • Unique culture: You'll be surrounded by some of the world's leading physicists, engineers, product, marketing and design people (to name a few!) with a strong desire to learn and transfer knowledge.
  • Meaningful values: You'll work with an incredibly supportive team who work consistently to deliver our core values to be real, be trusted, be just and to be revered.
  • Personal development: We provide you with a personal development and wellness budget.
  • Make a dent: Last but not least you'll have the unique opportunity to help set the direction for this revolutionary technology and truly make an impact that matters!
