Software Engineer Internship (September 2025)

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!

We are seeking a motivated and talented intern to join our Software Engineering team for a 6-month internship, starting in July/August 2025. This is a unique opportunity to be at the cutting edge of innovation, where you will contribute to the development of the software that powers Alice & Bob’s quantum computer. You will work closely with experimental physicists who conduct research on our cat qubits, and your contributions will directly impact Alice & Bob’s ambitious roadmap.

About the role:

As an intern, you will start by gaining a deep understanding of the code base for our core experimental framework. You will then be involved in the complete life cycle of a feature—interviewing expert users, understanding their needs, implementing, testing and deploying the feature. In particular, you will contribute to our data workflow by automating collection, processing, storage, and access to the data produced by our various teams. Expect to engage in meaningful work within a positive environment that fosters growth and learning!

Responsibilities:

• Gather and analyze requirements for a feature related to automation within our data pipeline
• Implement the feature while following established engineering best practices
• Test and demonstrate the feature, ensuring it meets the needs of our users
  
  
  

Requirements:

• Practical experience with Python and Git
• Practical experience with relational databases
• Good communication skills in English
• Familiarity with standard engineering best practices (e.g., testing, tooling, CI/CD) is a plus
• Experience with GitHub or GitLab is a plus
• A scientific background (in physics and/or electronics) is a plus
  
  
  

Benefits:

• 1 day off per month
• Meal Vouchers with Swile
• 50% Navigo reimbursement
  
  
  

Recruitment Process:

• Hiring Manager/Technical Interview with Adrien (60 min)
• Fit 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.
