Responsibilities
- Define and lead the architecture of the Quantum Infrastructure layer between low-level control software and user-facing services.
- Integrate requirements for qubit calibration, stabilization loops, and error-correction cycles with quantum hardware and control software teams.
- Design real-time and near-real-time feedback systems connecting hardware, error-correction logic, and automation systems.
- Architect data and service layers for quantum error-correction frameworks, lattice configurations, syndrome extraction, decoding, and long-term state tracking.
- Define a robust quantum circuit compilation stack supporting multiple frameworks and future upgrades.
- Serve as a technical authority, mentor senior engineers, influence cross-team technical direction, and drive architectural strategy and execution.
Requirements
- 12+ years building large-scale, high-reliability systems, infrastructure layers, or scientific platforms.
- Experience architecting complex infrastructure and data-heavy distributed systems.
- Superior proficiency in Python, asynchronous frameworks, service design, data orchestration, and performance optimization.
- Deep expertise with SQL, NoSQL, time-series, object storage, and distributed filesystem technologies.
- Hands-on experience with schedulers, workflow engines, configuration graphs, data pipelines, and other automation systems.
- Experience defining abstractions and synchronization mechanisms for hardware/software interaction loops.
- Understanding of containerization, Kubernetes, reproducible environments, multi-tenant architecture, and hybrid HPC/cloud deployments.
- Strong leadership ability to influence across teams, align with research and hardware groups, drive modernization, and execute at scale.
- Bonus: familiarity with scientific environments, low-level instrumentation flows, experimental automation, distributed scheduling, or HPC environments.
- Bonus: experience delivering hardware-backed products to external users and knowledge of Rust, C++, or Go for performance-critical or system-level components.
Benefits
- BSPCE equity plan and direct IP compensation bonuses for patents defining the quantum architecture.
- Flexible remote policy allowing up to 40% remote work per month.
- Parental benefits including crèche support or additional days off for caring for children under 12.
- Subsidized Urban Sports Club membership and mental health support through moka.care.
- 25 days of vacation plus RTT, in accordance with French law.
- Half of transportation costs covered or a yearly allowance for bicycle users.
- Competitive health coverage through Alan.
- Meal vouchers through Swile and access to a stocked kitchen.
- Company-covered French language courses.
About Alice & Bob
Alice & Bob develops fault-tolerant quantum computers based on superconducting “cat qubits” for research labs and industry exploring practical quantum algorithms. Founded in 2020 and headquartered in Paris with an office in Boston, this privately held company designs and fabricates its own processors and operates a prototyping cleanroom in Île-de-France. Its work spans quantum hardware, nanofabrication, and control software.
