Description du poste

Overview

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!

About the role

As a Senior Quantum Compilation Scientist, you will design, develop, and optimize the compilation toolchain that transforms quantum programs into physical gates for our quantum processors. This implies working at the intersection of quantum information science, theoretical computer science, computer architecture, and software engineering, and directly impacting the performance and scalability of our quantum systems.

Responsibilities

• Understand, design and build intermediate representations and a quantum computing compiler, to best use our fault-tolerant architecture.
• Ensure the integration of the compilation into Alice & Bob’s tool suite, and take into account user needs, interacting with the software and business teams.
• Design metrics for quantum compilers, and maximise performances of our compiler.
• Apply for and secure patents.
• Contribute to the scientific community by publishing your results and presenting your work at conferences.
• Mentor junior members of the team, interns, and PhD students.

Requirements

• 2+ years (post-PhD) of experience (or equivalent) in academia or industry (scientist position) on quantum computing or compiler design and implementation.
• Demonstrated expertise in at least one of the following areas: quantum compilation, quantum error correction, fault-tolerant quantum algorithms, classical language and compilation theory.
• Proficiency in Python and at least a compiled language e.g. C++, Rust, etc. (Experience with other relevant languages is a plus).
• Good attention to detail, analytical and problem-solving skills.
• Strong communication and collaboration skills.
• Professional-level English proficiency, both written and spoken.

Benefits

• 25-day vacation policy (as per French law) + RTT
• Half of transportation cost coverage (as per French law), or yearly allowance for bike enthusiasts
• 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
• Mental health support with moka.care
• Subsidized membership with Urban Sports Club

Recruitment Process

• Screening Call with Grace, Talent Acquisition Specialist (30 min)
• Hiring Manager Interview with Elie (60 min)
• Technical Interview/Presentation with the Team (90 min)
• Leadership/Fit Interview (45 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 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.
