Quantum Compilation Scientist at Alice & Bob (Paris)
Job Description
Alice & Bob is hiring a Quantum Compilation Scientist in Paris to develop, in theory and in code, the compilation tools and resource estimator that get the most out of its fault-tolerant cat-qubit architecture.
At a glance
- Role: Quantum Compilation Scientist
- Where: Paris, France, with remote work up to 40% of the month
- Contract: CDI (permanent)
- Level: PhD or equivalent in computer science, electrical engineering, physics or quantum information
- Apply: open until filled (re-checked 11 October 2026)
About the quantum compilation role
- Develop Alice & Bob’s compilation tool suite, through theoretical studies and implementation, to make the best use of its fault-tolerant architecture
- Update the resource estimator with the newest architectural improvements and make it usable by external users
- File patents, publish results and present them at conferences
- Mentor junior team members, interns and PhD students
Cat qubits store information in two coherent states of a microwave resonator, stabilised by engineered two-photon dissipation. That makes bit-flip errors extremely rare, so the remaining phase-flip errors can be handled with simpler codes, such as a repetition code. Roles at Alice & Bob are built around making that architecture work at scale.
The posting describes a staged hiring process: a screening call, an interview with the hiring manager, a technical session with the team including a presentation, leadership-team and fit interviews, and reference checks.
What Alice & Bob is looking for
- Expertise across quantum compilation, quantum error correction, fault-tolerant algorithms, and classical language and compilation theory
- A PhD or equivalent in computer science, electrical engineering, physics, quantum information science or a related field
- Python and at least one compiled language, such as C++ or Rust
- Strong analysis, attention to detail, teamwork and professional-level English
Nice to have
- Deep knowledge of graph theory or branch-and-bound and constraint-propagation algorithms
- Understanding of classical compiler back ends such as LLVM or GCC
- Broad knowledge of computer architecture and operating systems
Pay and location
Alice & Bob’s posting does not state a salary. The role is a CDI (permanent contract) based in Paris. The posting mentions an employee equity plan (BSPCE), bonuses for patents that shape the architecture, and remote work of up to 40% a month.
How to apply
Apply through the official Alice & Bob job posting. Alice & Bob’s posting does not give a closing date, so the role is open until filled; ResearchJobs.in will re-check this listing on 11 October 2026. Check the posting for location and work-authorisation details before you apply.

How to prepare for this application
- Cat-qubit architecture: read Alice & Bob's published resource estimates for cat-qubit computers and note which assumptions dominate.
- Compilation theory: revise intermediate representations, scheduling and routing, and how they map to fault-tolerant operations.
- Classical tools: be ready to discuss LLVM-style back ends or constraint solvers you have used.
- Show code: a Rust or C++ project with tests says more than a list of languages.
- Patents: think about which of your ideas were novel enough to protect; the role rewards this.
About Alice & Bob
Alice & Bob is a French company developing a universal, fault-tolerant quantum computer. Its approach uses a new kind of superconducting qubit, the Schrödinger cat qubit, which can correct some errors autonomously, so less hardware is needed for error correction than on other superconducting platforms. The company has more than 250 people from over 35 countries.
