PASQAL designs and develops Quantum Processing Units and dedicated software tools. Our 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. In addition to the outstanding computing power that they provide, QPUs are very energy efficient meaning that they will significantly contribute to reducing 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 benefits from numerous recent achievements in laser cooling of atoms, opto-electronics, vacuum and detection systems… Based in Massy and Palaiseau, at the heart of the Paris-Saclay quantum ecosystem, PASQAL is funded by Quantonation, a VC fund focusing on Quantum Technologies, and is attracting world-class investors.

Joining PASQAL is an opportunity to actively 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 technological 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.

Quantum Software Developer

Job Description

As a Kernel Quantum Software developer, your focus will lie on the further development of PASQAL’s low-level quantum software libraries, which serve as the interface between the user and the quantum devices, at various levels of abstraction and complexity.

These specific modules are the backbone of PASQAL’s software stack; they are exploited in-house by the Quantum Applications team as well as by the Clients who use our technology. Their quality is therefore of paramount importance for the development of PASQAL’s activity. You will support their constant progress taking into account the evolving Quantum Computing environment and scientific advances, while ensuring suitable performance and documentation.

This position is a job creation intended to support the strong growth in PASQAL’s Quantum Software team.

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

Qualification & Experience

  • MSc level or above in Computer Science, Electrical Engineering, Physics or related fields.
  • Solid knowledge and experience with Python 3.
  • Past experience in a comparable position and / or demonstrable contributions to open-source software projects.
  • Notions of quantum computing, atomic physics and optics.

Other valuable assets:

  • Exposure to hardware programming, particularly with microcontrollers or FPGAs.
  • Familiarity with other quantum programming frameworks, such as Cirq.


As the chosen candidate, your most valuable skill is the ability to write quality Python code that is well structured, tested and properly documented. You should be able to work independently with limited direction, in a code development environment where you will be asked to review others’ code, give meaningful feedback and be subjected to the same process. This also implies familiarity with version control, particularly with Git and GitHub.

Additionally, your position will involve close cooperation with other members of the software team, as well as frequent contacts with external collaborators on open-source projects. This will require a good level of interpersonal skills and the ability to work well with your peers.

Finally, as you will be integrated in an international working environment, fluency in written and spoken English is required.
