About Quandela:

Quandela is a European deeptech company building modular, scalable and energy-efficient spin-photonic quantum computers.

We develop the full quantum computing stack, from semiconductor quantum emitters and photonic processors to control systems, software and applications. Our platforms are available through the cloud and as on-premises systems.

Our ambition is to build fault-tolerant quantum computers capable of solving problems beyond the reach of classical computation.

The role:

We are looking for an AI Scientist to join Quandela’s AI and Quantum Machine Learning team in Massy (near Paris)

You will develop and evaluate machine-learning approaches for quantum computing, covering both:

• AI for quantum systems, including calibration, control, decoding for quantum error correction;
• quantum and hybrid machine learning, including rigorous comparisons with state-of-the-art classical methods, using MerLin, Quandela's framework for quantum machine learning.

You will work on research with colleagues across AI, quantum algorithms, software, product and hardware.

The Massy team is a central part of Quandela’s AI activities. This role therefore offers significant ownership and the opportunity to help shape and grow the team over time.

What You'll Do:

• Design, implement and train machine-learning and quantum machine-learning models.
• Develop AI methods to improve the calibration, control and performance of quantum systems.
• Benchmark classical, quantum and hybrid methods using meaningful baselines and evaluation metrics.
• Contribute actively to the development of the MerLin framework.
• Contribute to publications and collaborations with academic partners, including research ecosystem.
• Present your work internally and at scientific conferences and technical events.
• Help define Quandela’s future AI research directions and mentor junior researchers as the team grows.

Requirements

What we are looking for:

We are looking for an AI scientist, or an experienced industry practitioner with an equivalent background, who is eager to apply state-of-the-art classical machine-learning methods to scientific and engineering challenges in quantum computing. The role is primarily focused on using AI to improve quantum technologies, while also providing opportunities to develop and investigate quantum and hybrid machine-learning models.

• PhD + 3 years of experience or equivalent industrial R&D experience in machine learning.
• Strong foundations in modern machine learning, experimental methodology and model evaluation.
• Excellent scientific programming skills, particularly in Python and common machine-learning frameworks.
• Experience taking research ideas from initial exploration to robust implementation.
• Interest in working on both longer term research and concrete product problems.
• Strong communication skills and the ability to work autonomously within a focused, multidisciplinary team.
• Professional fluency in English.
  

Bonus Points

• Previous experience applying AI to physical systems, scientific computing, hardware control or experimental data.
• Knowledge of quantum computing, quantum machine learning or photonic quantum technologies.
• Experience mentoring junior researchers or helping define technical research directions.

Benefits

• Competitive salary, flexible based on your experience and expectations

• Profit-sharing & company savings plan
• 100% health coverage (Alan)
• 50% transport reimbursement or sustainable mobility bonus
• Meal vouchers (Swile), Gymlib fitness support
• Childcare assistance & referral bonuses (€1,000–€2,000)

Process: 

• Talent Acquisition Interview (30' - 45') 
• Hiring Manager Interview (45' - 60') 
• Reference checks 
• Technical discussion and presentation of previous research work 
• Meeting with the team
• Offer 

Beyond That:
At Quandela, we value scientific curiosity, experimentation and collaboration. If you're passionate about quantum optics, spin physics and quantum technologies, we'd love to hear from you, even if you don't meet every listed requirement. 

If you're excited by the challenge of turning scientific ideas into demonstrations, advancing the building blocks of future quantum computing systems and working alongside physicists, engineers and theorists, let's talk.
