The Role
Design and build a middleware layer for client applications and databases. Responsibilities include implementing a Python HTTP service, creating a REST API, and deploying the service using Docker.
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're a diverse team of 140+ brilliant minds from over 20 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
Join the Framework Team, responsible for developing software that supports experimental physicists and theoreticians. No prior quantum knowledge is required!
Your mission will be to design and build the middleware layer connecting client applications to multiple services and databases, managing experimental data, session workflows, and instrument access control. This backend is set to be at the center of our experimental platform, used daily by physicists of different profiles to design and characterize quantum chips.
This internship is set to take place during the first semester of 2026, and last at least 5 months.
Responsibilities:
- Design and implement a Python HTTP service that serves as an integration layer connecting a Python client library with existing PostgreSQL databases and web services
- Define and document a clear REST API (endpoints, request/response schemas, error codes)
- Handle authentication, logging and observability
- Develop the Python client library to interface with the backend
- Deploy the service as a containerized application on our internal network using an infrastructure-as-code framework
- Write tests and documentation
- Collaborate with the Cloud team, the Software team and end users (quantum physicists), ensuring a smooth integration with backward compatibility where needed
Requirements:
- Even as we work toward building a quantum computer, strong classical software engineering remains essential.
- Enrolled in or completed a Master’s in Computer Science, Software Engineering, or equivalent
- Proficiency in Python
- Familiarity with web development and SQL databases. Knowledge of SQLAlchemy and PostgreSQL is a plus
- Working knowledge of Git for version control
- Experience with Python web frameworks such as Django, FastAPI, or Flask is a plus
- Good communication skills with end users and other software engineers
- Experience or interest with CI/CD pipelines and deployment tools like Docker
- Proactive, autonomous, rigorous
- Fluency in English. You will be working within a French team, so proficiency in French is considered an asset.
Benefits:
- 1 day off per month
- Half of transportation cost coverage (as per French law)
- Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
