Scientific Python Engineer – Quantum Calibration

Calibration Scientific Software Developer

Alice & Bob is building the first universal, fault-tolerant quantum computer, based on an innovative Schrödinger cat qubit architecture ⬛ capable of implementing quantum error correction autonomously.

Within the Calibration team, you will contribute to developing scientific tools that automate the calibration of our QPU and maximize its performance. We are looking for someone with strong Scientific Python expertise who can work on experimental data analysis, scientific automation, and building robust software tools.

Responsibilities

• Develop Python tools for analyzing experimental QPU data (signal processing, fitting, parameter extraction, visualization).
• Design and maintain internal APIs and helper libraries that physicists use to write automatic calibration procedures.
• Collaborate closely with physicists to improve automation of recalibrations and the reliability of analysis workflows.
• Implement unit and integration tests to ensure robustness and reproducibility of scientific tools.
• Generate automated calibration reports including raw traces, fitted models, metrics, and provenance metadata.
• Enhance the user experience for physicists by providing clear documentation, examples, and templates.
• Debug and continuously improve calibration workflows.

Required Profile

• 5+ years of experience in scientific or instrumentation software development.
• Strong proficiency in Python and the Scientific Python ecosystem (NumPy, SciPy, matplotlib, pandas, etc.).
• Experience in experimental data analysis, signal processing, or numerical modeling.
• Experience designing APIs or internal libraries for scientific users is a plus.
• Strong testing practices (pytest), version control, and reproducible environment management.
• Excellent debugging skills and ability to work closely with experimental physicists.
• Pragmatic mindset, balancing scientific rigor with practical efficiency.
• 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
• A Parental plan including additional benefits such as crèche support or additional days‑off to take care of under 12 years old children
• Subsidized membership with Urban Sports Club
• Mental health support with moka.care
• 25-day vacation policy (as per French law) + RTT
• Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
• Competitive health coverage, with Alan.
• Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
• French language courses covered by the company for those interested
