Software Architect - Calibration (H/F)

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. We are 100+ and counting, between physicists, PhDs, engineers and experienced business professionals, all united to reach our ambitious goal. Are you ready to take on unprecedented challenges and contribute to revolutionizing technology? Join us, and let's shape the future of quantum computing together!

About the role

The Calibration team automatizes calibrations of our cat‑qubit Quantum Processing Unit (QPU) to maximize performance and keep the processor in working condition. AsCalibration Software Architect , you will own the high‑level design and evolution of the automatic calibration software stack. You will define interfaces to the measurement software and calibration database, set standards for reliability and observability, and ensure the stack scales from lab prototypes to production usage. You will work closely with lead physicists, automation engineers and platform teams to translate scientific needs into a robust, maintainable architecture.

Responsibilities

• Define and maintain the overall software architecture for calibration orchestration, storage, QA gates, and operator tooling.
• Design clear interfaces between calibration blocks, the orchestration/DAG controller, acquisition hardware, and the calibration database.
• Drive API standards so that the automatic calibration blocks are composable, versioned, user-friendly and reproducible.
• Lead cross‑team integration with platform, firmware, and measurement software teams.
• Establish testing and deployment patterns for CI/CD, releases and rollback strategies.
• Mentor engineers on design reviews, architecture tradeoffs, and long‑term technical roadmaps.

Requirements

• 5+ years software engineering experience with at least 3 years in system or software architecture roles.
• Strong experience designing distributed systems and integration patterns for hardware control or instrumentation.
• Track record of successfully defining and implementing clear architectures.
• Proficiency inPython and CI/CD.
• Excellent communication skills and experience coordinating cross‑discipline teams

Benefits

• Our success is your success : own it with ourBSPCE plan
• Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture
• Flexibleremote policy, up to 40 % a month
• AParental Plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
• Subsidized membership withUrban 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
