Mid-Senior Quantum Algorithms Scientist

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.

The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!

We are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.

Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!

Joining our applications team as a Quantum Algorithms Scientist, you will be responsible for charting the course toward practical applications of fault-tolerant quantum computing by optimizing algorithms for our specific architecture.

You will work on developing the earliest applications of fault-tolerant quantum computers: many body problems (condensed matter, chemistry, etc.). You will also focus on optimizing the fault-tolerant implementations for Alice & Bob's architecture, in collaboration with the quantum error correction team. As a scientific expert on our technology, you will contribute to scientific collaborations with academic and industry partners.

Responsibilities:

• Develop novel quantum algorithms.
• Optimize the implementation of quantum algorithms to our architecture, and challenge it.
• Work on the first unchallenged quantum advantage (as soon as Alice & Bob's hardware becomes available).
• Participate in scientific collaborations with academic and private partners.
• Perform literature reviews and syntheses to understand the potential of quantum computing for specific industries.
• Collaborate closely with our clients’ R&D experts to mature their quantum computing use cases.
• Partner with Alice & Bob’s clients and strategic partners to develop quantum algorithms tailored to their specific needs.

Requirements:

• A PhD or 3+ years research experience in quantum computing, condensed matter, quantum chemistry or nuclear physics. Demonstrated research track record.




We’re also looking for:

• Strong experience with software design and best practices.
• Understanding of quantum computing and error correction.

Benefits:

• 25-day vacation policy (as per French law) + RTT
• Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
• Competitive health benefits with Helium/AXA
• Meal vouchers with Swile, as well as access to a fully equipped kitchen
• Parental benefits with crèche support
• Flexible remote policy, up to 40 % a month
• Language courses covered by the company

Recruitment Process:

• Screening Call with Grace, Junior Talent Acquisition Specialist (45 min)
• Hiring Manager Interview (45 min)
• Technical Interview/Presentation with the Team (60 min)
• Fit Interview (45 min)
• Founders/C-level Interview (30 min)
• Reference check

Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
