About Pasqal

PASQAL designs and develops Quantum Processing Units (QPUs) and associated software tools.
Our innovative technology enables us to address use cases that are currently beyond the reach of the most powerful supercomputers; these cases can concern industrial application challenges as well as fundamental science needs.
In addition to the exceptional computing power they provide, QPUs are highly energy efficient and will contribute to a significant reduction in the carbon footprint of the HPC industry.


Job Description

Pasqal's ambition is building and developing Quantum Processing Units (QPU) enabling highly performant computation using neutral atoms manipulated with lasers. On the hardware level, the complexity of the setup makes this journey unique and interesting. In the system performance team, we measure and optimize the performances of the QPU. We are responsible for the implementation and validation of new features and to push the system at its higher level of performances.

As a System Performance Engineer, your main responsibilities will be:

  • Contribute to QPU wide projects

  • Analyze performances (by developing simple mathematical and physics models and simulations) on current design and identify main limitations

  • Propose new design or new techniques (hardware/software)

  • Propose and perform documented system and sub-system tests plans to validate performance increase or new feature

  • Contribute to maintaining dev QPUs in operation

  • Propose new ideas leading to industrial innovation

  • Collaborate closely with other teams in the hardware department

  • Support the Manufacturing & Support team

  • Communicate scientific results within and outside the team

  • Supervise junior engineers and master students

To be successful in this role, you will have the following:


Requirements:
• M2 in physics +2/3 years in industry or PhD
• Knowledge in experimental physics (atom-light interaction physics would be appreciated)
• Strong interest in experimental physics and physics models
• Programming skills for data analysis and simulations (Python, ... )
• Versioning control is a plus (git tools)
• Experience in managing small-scale projects

Soft Skills:

  • Autonomy, rigor and organization

  • Communication and listening skills

  • Proven ability to collaborate with multi-disciplinary teams (Theory, Experimental)

  • Good level of written and spoken English. French is a plus but not required
