Senior Quantum Algorithm Developer - W/M

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 

As a Senior Quantum Algorithm Developer – Primitives you will design, implement, and optimize analog quantum algorithms running directly on Pasqal’s neutral-atom hardware. Your primary focus will be on state preparation protocols, analog control strategies for efficient characterization, benchmarking, and algorithmic applications. 

As part of your role, you will also lead diverse research efforts that explore the boundaries of quantum advantage, investigate computational hardness and resource tradeoffs, and prototype new algorithms that could run on Pasqal's hardware. You will collaborate closely with hardware and software teams to guide the co-design of algorithms and architectures you are also expected to help shaping the roadmap for algorithmic utility on neutral-atom systems. 

Your missions and responsibilities will include: 

• Design and optimize analog state preparation protocols, including adiabatic, variational, counter-diabatic, and optimal-control approaches. 

• Conduct original research in quantum algorithms, quantum algorithm complexity, and quantum information theory. 

• Design and benchmark algorithmic primitives aligned with neutral-atom capabilities. 

• Collaborate with application teams to optimize performance under realistic architectural constraints. 

• Contribute to the software stack, including prototyping, maintaining, and improving libraries. 

• Document and publish results internally and externally, contributing to the company’s scientific visibility. 

• Keeping a regular technological watch.  

• Having an inventive activity in the scientific and technical fields related to the Company's research, products, technologies and markets; filing patents.
