Processing Hardware Engineer - M/F

About Pasqal

Pasqal designs and develops quantum processors (QPUs: Quantum Processing Units) and associated software tools.

Our innovative technology enables the processing of use cases that are currently beyond the reach of even the most powerful supercomputers; these cases can concern both applied industrial challenges and the needs of fundamental sciences.

Beyond the exceptional computing power they provide, QPUs are highly energy-efficient and will contribute to significantly reducing the carbon footprint of the high-performance computing industry.

Job Description

As part of our growth, we are recruiting a Processing Hardware Engineer M/F to strengthen our Quantum Process team. Within the Hardware department, the Processing team develops and validates the physical operations executed during the computation phase of PASQAL's neutral-atom QPUs (e.g., 1-qubit / 2-qubit gates).

We are looking for a profile oriented towards theory/modeling, capable of contributing to both short-term performance improvements and the medium/long-term evolution of processing capabilities, in connection with the hardware roadmap.

Your Missions:

• Design, implement, and optimize processing operations (state preparation, gates, dynamical decoupling, coherent transport) on our QPUs
• Implement optimal control methods under realistic hardware constraints (bandwidth, noise, crosstalk...)
• Identify dominant error sources, develop/maintain noise models, and establish error budgets
• Link operational-level errors to circuit/digital performance (end-to-end simulations, benchmarks, sensitivity analyses)
• Contribute to medium/long-term processing directions in coordination with other teams
• Develop and maintain internal simulation/emulation libraries consistent with experimental data

About You

• PhD in AMO physics (atomic, molecular, and optical physics) / quantum information
• Solid understanding of neutral-atom platforms (trapping, cooling, lasers, noise...) and their impact on operations
• Ability to model real imperfections (lab experience appreciated)
• Very good scientific programming skills (e.g., Python), data analysis, and simulation
• Autonomy, rigor, interdisciplinary collaboration, clear communication
• Good level of English (written/oral)
• Experience: PhD + 0–5 years

What we offer

• New offices in Massy
• A flexible on-site rhythm (2-3 days of teleworking per week)
• Contract type: CDI (Permanent contract)
• A dynamic and close-knit international team
• A key role in a fast-growing start-up
• Free time for training and attending conferences/meetups

Recruitment Process

• A 30' interview with our talent acquisition
• An exchange with your future manager
• A meeting with the team in our offices
• An offer!

Pasqal is an equal opportunity employer. We are committed to creating a diverse and inclusive workplace, as inclusion and diversity are essential to achieving our mission. We encourage applications from all qualified candidates, regardless of their gender, race, ethnic origin, age, religion, or sexual orientation.

About Us

Pasqal designs and develops Quantum Processing Units and dedicated software tools.

As they are very low energy intensive, they will significantly contribute to reduce the carbon footprint of the computing industry. With partnerships with key users in the fields of energy, IT, finance, drug and chemical design, automotive PASQAL is a true leader in the Neutral Atom Quantum computing space.

Job Description

Within PASQAL’s Hardware department, the Processing team develops and validates the physical operations executed during the processing/computation phase of our neutral-atom QPUs (e.g., 1-qubit and 2-qubit gates). The team brings together experimental and theory/numerical profiles to ensure continuous alignment between modeling and experimental reality.

We are looking for a theory-leaning profile who will contribute to both near-term performance improvements and the medium/long-term evolution of processing capabilities, in line with the hardware roadmap.

What you will do

• Protocols development & deployment: Design, implement, and optimize processing operations (state preparation, gates, dynamical decoupling, coherent transport) on Pasqal QPUs.

• Optimal control: Apply optimal-control methods to improve operation performance under realistic hardware constraints (bandwidth, noise, crosstalk, etc.).

• Error modeling & budgets: Identify dominant error sources, build/maintain physical noise models, and quantify their impact on operation fidelity (error budgets).

• Circuit-level performance: Propagate operation-level errors to digital circuit performance (end-to-end simulations/benchmarks, sensitivity analysis) to guide protocol choices and hardware priorities.

• Medium-/long-term roadmap: Contribute to the definition of medium-/long-term processing directions in coordination with other teams.

• Simulation & emulation tools: Develop and maintain internal libraries to simulate operations and circuits under realistic conditions and ensure consistency with experimental data.

About you

• PhD in AMO physics (Atomic, Molecular & Optical) / Quantum Information
• Solid understanding of neutral-atom platforms (trapping, cooling, lasers, noise sources) and their impact on operations
• Strong understanding of experimental constraints (hands-on lab experience is a strong plus) and ability to model real-world imperfections
• Strong programming skills for scientific computing (e.g., Python), including data analysis and simulation workflows
• Experience driving small technical projects (planning, prioritization, delivery)
• Autonomy, rigor, ability to collaborate across disciplines, strong communication & listening skills
• Good written and spoken English
