Company mission
To shape the technological landscape of the 21st century.
Role
Who you are
- You hold a Master's degree in Physics, Maths, Computer Science or equivalent, with a minimum of 5 years of experience with software development in industry/research/open-source projects
- Experience with software best practices in a collaborative environment, cycles of development, unit testing, CI/CD pipelines
- Excellent writing of production-level Python
- Strong foundations in maths
- Knowledge of quantum computing
Desirable
- Experience contributing to open-source projects
- Experience with ML frameworks (i.e. PyTorch and JAX)
- Experience with OR frameworks
- Knowledge about containerization technologies (i.e Docker/Singularity)
What the job involves
- Participate in the rapid development of a deep-tech start-up at the forefront of the second quantum revolution!
- As a Senior Quantum Software Engineer, your tasks lie in the development, optimization and maintenance of Pasqal’s ecosystem of open- and closed-source quantum software libraries
- He primary focus is on solvers, a set of software libraries featuring algorithms for neutral atoms quantum computers
- This includes classical and quantum algorithms for solving graph machine learning, optimization, and quantum simulation problems
- Developing and maintaining Pasqal core algorithm libraries
- Transferring research ideas from the quantum algo teams into production-grade code; writing structured, documented and tested quality code
- Building automated pipelines that leverage the solvers for solving client use cases in various industries
- Collaborating with the different R&D teams to drive the content and structure of the software stack
- Ensuring the interoperability of the Application software stack with the rest of the libraries, in collaboration (among others) with the lower-level software stack components and with the Hardware teams
- Helping and supporting the users (including internal algo developers as well as external ones) in their adoption of the libraries
- Actively contributing to the development and productization strategy of our quantum software stack
- Keeping a regular technological watch and participating in conferences
- Having an inventive activity in the scientific and technical fields related to the Company's research, products, technologies and markets; filing patents

Our take
Classical computing, using bits made up of ones and zeros, has almost reached the physical limits of its capabilities, with engineers running out of ways to fit more transistors onto a computer chip. Meanwhile, the processing demands on computing hardware only increase. Quantum computers have long been posited as a solution to this issue, with processors able to exploit quantum mechanics to perform calculations exponentially faster than any classical computer. Founded by a Nobel Prize for Physics recipient, Pasqal exists to bring quantum computing out of the realm of scientific research (and science fiction) and into the business world for the first time.
Pasqal is not alone in the race to produce quantum computers, and it faces competition from well-funded rivals such as IonQ and IBM. However, it is pursuing a different technological line - neural atom computing, which can manipulate individual atoms with laser tweezers. This has the advantage of being more scalable and energy efficient, and can run at room temperature rather than requiring supercooling.
In 2025, Pasqal closed an equity funding round from LG Electronics, a partnership which will see the companies work together to solve multiphysics simulation and optimisation challenges for LG. Having successfully built proof of concept models and overcome the technical challenges of manipulating a few and then hundreds of atoms, Pasqal is building a bespoke control system and beginning to implement quantum algorithms. Pasqal was also awarded one of five grants from the French Ministry of Defence in 2024, as part of a government plan to create 2 universal quantum computer systems for defence purposes by 2032. This new development indicates Pasqal's expansion from solely business purposes into new sectors where its technology can be impactful.
