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, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.
Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!
About the role:
We are looking for a Senior Infrastructure Engineer to own the technical evolution of our hybrid infrastructure (on-premise/cloud). You will be the technical reference for architecture, design, and implementation of the company's infrastructure projects in the quantum computing field.
Responsibilities:
Architecture and design: Design infrastructure solutions adapted to our quantum measurement needs and define technical standardsStrategic projects: Lead high-impact projects such as: JupyterHub migration to Kubernetes for our data science workflowsInternal cluster consolidation and optimizationScalability solutions for our growing quantum measurement resource requirementsTime-stamping infrastructure evolution and improvementsDocker → Kubernetes migration for legacy applicationsInfrastructure management: Implement and maintain servers supporting our quantum operationsObservability: Complete the deployment of our monitoring stack (node-exporter, Grafana) across all infrastructureInnovation: Propose and implement solutions to support the company's rapid growth and evolving quantum computing needsTechnical advisory: Support teams on infrastructure matters and drive continuous improvement
Technical environment:
OS: Mainly Linux (Ubuntu), a few Windows serversContainerization: Docker, Kubernetes (internal cluster)Infrastructure: Hybrid on-prem/cloud architectureMonitoring: Grafana, node-exporter, PrometheusIaC: Terraform, AnsibleDevelopment: Python widely used across the stack
Requirements:
Solid experience (5+ years) in infrastructure and systemsCore expertise: Linux (Ubuntu), system architecture, containerization (Docker/Kubernetes)Python (scripting, code understanding)JupyterHub (administration and deployment) - a real plusDesigning scalable architectures for high-performance computing needsHands-on experience operating and maintaining Kubernetes in production environments. Proficiency in Python, including scripting, automation, and the ability to understand and review application code. Experience with JupyterHub in administration and deployment; exposure to multi-user, scalable notebook environments is a strong plus.
