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.

GPU Engineer

Job description

By allowing the efficient classical simulation of physics at the atomic level, GPU-based algorithms play an important role to explore the performances of Quantum Algorithms designed to ultimately run on Pasqal neutral-atom-based Quantum Processing Units (QPUs).

Within the Quantum Software and Applications department, you will be in charge of developing and extending our computational infrastructure according to these needs. As a GPU Engineer, you will be in charge of a computational cluster and you will use it to run intensive numerical jobs in order to assess the feasibility of analog/digital quantum circuits to be run on QPUs.

You will be given the autonomy and resources to design and build a top-class infrastructure. Associated responsibilities will include among others:

  • conducting research and surveys on emerging technologies, HPC workloads and algorithms, and requirements induced on computer architecture;
  • analyzing and reporting on workload performance on new computing architectures;
  • optimizing the architecture to maximize performance of a variety of quantum algorithms.

Within PASQAL, your assignments will range from developing and maintaining PASQAL’s GPU cluster, to running state of the art algorithms for quantum dynamics and parameter optimization while ensuring the highest overall performance. You will also be involved in the design and the implementation of new algorithms, and in the simulation of various layers of our stack. For this purpose, you will collaborate with the other hardware and software teams of PASQAL, composed of scientists and engineers from a wide range of specialties.

This position is a job creation, to foster the growth of PASQAL’s activity.

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

Qualification & Experience

You hold a MSc or higher level in Computer Science/Physics/Mathematics or related fields.

You have a minimum of 3 years’ experience in GPU programming, parallel processing and High Performance Computing (HPC).

You have in-depth knowledge of C++/Python, CUDA, OpenCL or similar packages.

Previous hands-on experience with building GPU and cluster infrastructure is mandatory.

Notions of quantum computing, atomic physics and optics, as well as a previous experience in digital simulation of quantum system, are assets that will be highly valued.


The successful candidate will have a strong interest for Quantum Information, Computing and Simulation, as well as a vision for industrializing deep techs.

We are looking for someone who is really excited about our technologies and the scientific challenge that we are facing.

In this position you will build upon your strong interpersonal skills and ability to work within a team on a broad sense. This will among others include collaborating with software and hardware teams and reporting out findings to extend cross organization.

As you will be working daily amidst an international environment, fluency in written and spoken English is required.

We are an Equal Opportunity Employer.
