PASQAL designs and develops Quantum Processing Units and dedicated software tools. These innovative processors address applications which are out of the reach of the most powerful existing supercomputers, encompassing real-world challenges as well as fundamental science. As they are very low energy intensive, they will significantly contribute to reduce the carbon footprint of the computing industry.

PASQAL has partnerships with key users in the fields of energy, IT, finance, drug and chemical design, automotive… The maturity and potential of our technology and the quality of our scientific team has been rewarded several times at French, European as well as global levels.

Our technology builds upon considerable knowledge accumulated over decades by the Institut d’Optique near Paris (IOGS / CNRS); it makes the best of numerous recent achievements in laser cooling of atoms, opto-electronics, vacuum and detection systems. Based in Massy and Palaiseau, at the heart of the quantum ecosystem south of Paris, PASQAL is funded by Quantonation, a VC fund focusing on Quantum Technologies, and is attracting world-class investors.

Joining PASQAL is an opportunity to contribute to the rapid development of a Deep-Tech startup at the forefront of the second Quantum Revolution. You will be directly involved in one of the greatest challenges ever, shaping the technology landscape of the 21st century. You will work among top-class engineers and scientists, competing against the world’s biggest players.

System Software Engineer
Quantum Processor Operating System

Job description

You will join the development team in charge of developing the software that controls PASQAL Processing Units.

Running on main classical CPUs, this operating system interfaces a set of hardware devices connected together in a local network architecture. At low level, the operating system manages the generation and the monitoring of numerous I&O electronic signals in real-time; dedicated electronic modules are developed in collaboration with the team of electronics engineers. At high level, it manages complex automation tasks combining execution of external job requests and self-recalibration of various internal parameters. The operating system is the main entry point to the Quantum Processors, both for PASQAL engineers and for external users. It also enables PASQAL teams to integrate, operate and maintain the QPUs.

Your key missions will include:

  • Taking responsibility for development of software components: design, implementation, test, HW/SW integration, CI, documentation and support.
  • Analysing inputs from the system engineers, to translate them into software requirements.
  • Proposing solutions and prototyping them to solve technical challenges.
  • Ensuring software robustness, reliability and maintainability.
  • Participating in UI implementation.
  • Collaborating with PASQAL’s electronics team to co-developed features and functions.
  • Having an inventive activity in the scientific and technical fields related to the Company’s research, products, technologies and markets; filing patents.

This position is a job creation to support the strong growth of PASQAL’s Engineering and Production team.

Location: Massy – Palaiseau (Southern Paris area – France)
Start date: position available now
Type of contract: permanent contract
