Calibration API Software Engineer

Alice & Bob is developing the first fault-tolerant universal quantum computer, designed to solve some of the world's most complex problems. The quantum computer we are designing is based on a new type of superconducting qubit: the "cat" Schrödinger qubit. Compared to other superconducting platforms, this technology allows for autonomous quantum error correction, paving the way for more reliable and scalable systems.

We are an international team of over 140 talents from more than 20 countries, united by a common goal: to revolutionize computing with a fault-tolerant and truly usable quantum machine. Are you ready to take on unprecedented challenges and help shape the future of quantum computing?

Job Context

The Calibration team automates the calibrations of our cat-qubit Quantum Processing Unit (QPU) to maximize its performance and maintain the processor in operational condition.

As a Calibration API Software Engineer, you will develop and maintain the calibration API and associated Python libraries used by physicists to write automatic calibration blocks, analysis routines, and calibration reports.

Your role is central to ensuring that these tools are robust, well-tested, compatible with CI/CD pipelines, and perfectly integrated with the internal QPU acquisition and control software.

Responsibilities

• The Calibration team automates the calibrations of our cat-qubit Quantum Processing Unit (QPU) to maximize its performance and maintain the processor in operational condition.

Qualifications

• Minimum 5 years of experience in scientific or instrumentation software development, ideally in Python.
• Excellent command of Python, with solid experience in API design, static typing, and linting tools (mypy, pylint).
• Strong debugging skills and a pragmatic approach to balancing software robustness and scientist productivity.
• Experience with testing frameworks (pytest), CI/CD systems, and writing integration tests.
• Ability to produce clear documentation, examples, and developer tools suitable for non-specialist users.

Benefits

• Our success is your success: equity participation via a BSPCE plan.
• Direct compensation linked to intellectual property, with significant bonuses for contributions to structuring patents of the quantum architecture.
• Flexible remote work policy, up to 40% per month.
• Parental support including additional benefits (childcare assistance, extra leave days for children under 12).
