The Role
The Junior Quantum Compilation Scientist will optimize quantum programs for efficiency, contributing to the compilation tool suite and engaging in research and publication tasks.
Summary Generated by Built In
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
We're looking for a highly skilled and motivated Junior Quantum Compilation Scientist to help us build the future of our quantum systems. You will be a key contributor in the design and implementation of our compilation suite, tackling the challenge of optimizing quantum programs for maximum efficiency on our processors. This is an essential, interdisciplinary role that merges expertise in quantum physics, theoretical computer science, and high-performance software engineering to directly boost the speed and reliability of our quantum hardware.
Responsibilities
- Work on Alice & Bob’s compilation tool suit, both with theoretical studies and implementation, to ensure the best use our fault-tolerant quantum computer architecture.
- Survey the tools provided by the ecosystem.
- Share team accomplishments with the rest of Alice & Bob.
- Fill patents, publish your results in scientific publications and present them at conferences.
Requirements
- Demonstrated expertise in quantum compilation, quantum error correction, fault-tolerant quantum algorithms, classical language and/or compilation theory.
- Master's degree or equivalent in Computer Science, Electrical Engineering, Physics, Quantum Information Science, or a related field.
- Proficiency in Python and at least a compiled language (e.g. C++, Rust, etc.); experience with other relevant languages is a plus.
- Tangible interest in quantum computing.
- Strong analytical and problem-solving skills, with a keen eye for detail.
- Excellent communication and collaboration skills, with the ability to work effectively in a cross-functional team environment.
- Professional-level English proficiency, both written and spoken.
Nice to Have
- Demonstrated expertise in graph theory or branch & bound/constraint propagation algorithms.
- Solid understanding of classical compiler backends (e.g., LLVM, GCC) or high-performance or specialized computing compilers.
- Strong command of computer architecture and operating systems.
Benefits
- Our success is your success : own it with our BSPCE plan
- Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
- Flexible remote policy, up to 40 % a month
