As a Senior Quantum Control Engineer, you’ll be responsible for developing control solutions for quantum technologies and deploying them in the Q-CTRL product suite.


  • Develop control solutions for quantum technologies and deploy them in the Q-CTRL product suite - including research, demonstrations, software development, testing, performance, reliability and documentation
  • Focus on the creation of control solutions for quantum computers realized in various technologies, including superconducting circuits
  • Apply optimization and machine learning techniques for both performance enhancement and analysis
  • Develop publicly available and high quality software using Python
  • Collaborate with your colleagues in the Quantum Control Engineering and Software Engineering teams
  • Explain and document sophisticated control solutions in accessible language
  • Consult with the Lead Quantum Control Engineer, stakeholders and the broader team on decisions for all new products and features
  • Interact with customers as needed to deliver solutions which help them achieve their goals


  • Superconducting Circuits
  • Quantum Control
  • Optimal Control
  • Machine Learning
  • Python


PhD in Physics, Engineering or a closely related discipline.


  • You embody Q-CTRL’s core values and you demonstrate them in your words and actions both internally and externally - you’re real, trusted, just and revered.
  • You understand that communication is the biggest responsibility of your role and the one you’re least likely to get right unless you focus on it.
  • You care about how your attitude affects those around you. Everything you do runs through this filter.
  • You are humble enough to bend to the will of the frameworks, technologies, constraints, and people you work with when doing so won’t have a materially negative impact. In other words, you can play by someone else’s rules when that’s the best thing to do.
  • You make pragmatic (often boring) technology choices at work and you play in your free time.
  • You love to teach and learn from your co-workers.
  • You don’t mind being the one that looks bad. You make mistakes sometimes. You choose to fix them and learn from them.
  • You are confident with a number of programming languages, operating systems, and architectures. You probably have one of each you prefer right now, but you’re neither dogmatic nor myopic in your focus on them.
  • You display The Three Virtues of a GREAT Programmer
