About PASQAL
PASQAL designs, develops and commercializes quantum processors (QPUs) based on neutral atoms cooled by laser technology. These extremely complex machines combine multiple high-level technical domains, including optics and lasers, electronics, optomechanics, software, precision mechanics and high-vacuum systems.
Our technology enables applications that are currently out of reach for today’s most powerful supercomputers, while significantly reducing the carbon footprint of high-performance computing thanks to exceptional energy efficiency.
Job Description
As part of the deployment of our QPUs manufactured at our Massy site, we are looking for an Installation & Maintenance Engineer – Complex Machines (Optics / Lasers) who will work at the heart of highly advanced technologies. As QPUs rely extensively on complex optical and laser architectures, we are seeking a candidate with strong knowledge in these fields.
You will join the Installation & Maintenance team (10 engineers) within the Production & Project Management department. This team is responsible for the installation, commissioning, acceptance testing and maintenance of QPUs on site—either at PASQAL or at customer data centers (HPC sites in France, Europe and the Middle East).
This role places you directly at the core of our optical technologies: you will work on complex laser systems, multi-axis optical benches, high-precision alignments and advanced optical diagnostics.
We are recruiting a Installation & Maintenance engineer to reinforce our support team. In this context, your main missions will be :
- Install and commission QPUs on internal or customer sites, with a key role in optical alignments, laser tuning and validation, as well as performing hardware/software upgrades.
- Participate in final on-site acceptance testing and functional validation.
- Receive, analyze and follow customer issues until resolution.
- Perform diagnostics to identify root causes of failures and coordinate the required technical interventions.
- Intervene on site to restore machines to operational state and deploy corrective actions.
- Contribute to the development and validation of diagnostic, maintenance and repair procedures, working closely with optics, optomechanics, electronics, mechanics, software and production teams.
- Document incidents, ensure full traceability of interventions, and contribute to the continuous improvement of QPU reliability.
The position is based in Massy, with occasional travel from several days to several weeks in Europe and the Middle East.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
BLOCK 1 — EXECUTIVE SNAPSHOT
This critical field engineering function is essential for achieving commercialization maturity and hardware uptime in the neutral atom quantum computing modality. The role serves as the primary interface between advanced core R&D and live customer deployment environments, directly mitigating the most acute risk factor in the hardware stack: sustained optical system stability and alignment within high-vacuum environments. By assuring the reliability and rapid commissioning of complex laser architectures integral to Qubit manipulation, this engineer transforms prototype systems into enterprise-grade computational assets capable of integration within existing High-Performance Computing (HPC) infrastructures.
BLOCK 2 — INDUSTRY & ECOSYSTEM ANALYSIS
The quantum hardware market is currently transitioning from proof-of-concept demonstrations to scalable, deployable systems, a phase heavily constrained by the physical logistics and inherent instability of complex hardware modalities, particularly neutral atom architectures. Pasqal's reliance on precise laser control for qubit addressing and entanglement places this role squarely within the critical path of technology readiness level (TRL) progression. The prevailing scalability bottleneck is no longer confined solely to gate fidelity or qubit count, but extends profoundly into operational stability, Mean Time Between Failures (MTBF), and the ability to maintain ultra-precise optical alignment across varied global customer sites, often co-located with traditional data centers. This role addresses a key workforce gap: the scarcity of engineers capable of bridging deep physics/optics expertise with rigorous, field-proven industrial installation and diagnostics protocols. The competitive landscape demands robust hardware reliability to differentiate from superconducting and ion trap rivals; therefore, the ability to rapidly diagnose and restore highly complex, multi-domain (optics, vacuum, electronics) system failures is paramount. Successful deployment in HPC sites in Europe and the Middle East signals a critical market expansion, which is only sustainable if operational uptime—governed by the effectiveness of this maintenance team—is consistently high, validating the neutral atom QPU as a viable, energy-efficient alternative to classical supercomputing.
BLOCK 3 — TECHNICAL SKILL ARCHITECTURE
Expert proficiency in laser physics and applied optics is fundamental, enabling the high-precision alignment required to sustain the quantum state integrity of the neutral atoms. This competency ensures the requisite photon flux and temporal coherence are maintained for optimal gate operations, translating directly into system stability and low error rates over extended operating periods. Deep knowledge of sophisticated troubleshooting and failure analysis techniques provides the rapid diagnostics capability necessary to isolate root causes within highly coupled systems (e.g., distinguishing an optomechanical drift from an electronics fault or vacuum degradation). The integration of technical skills across electronics, precision mechanics, and high-vacuum systems establishes a versatile, full-stack understanding of the QPU hardware, facilitating comprehensive, one-touch interventions. This multi-domain mastery is essential for minimizing system downtime and ensuring that maintenance procedures—developed and validated by this function—are standardized, repeatable, and scalable across a growing fleet of deployed machines.
