Senior Site Reliability Engineer Growth IT and ML Ops Paris Paris CDI 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're a diverse team of 250+ brilliant minds from over 35 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together! About the role We're a fast-moving scale-up and our infrastructure needs to keep pace. That’s why we're looking for a Senior Site Reliability Engineer to own the reliability, automation, and security of our GCP platform, and to set the bar for how we run production as we grow. You'll spend most of your time building and operating systems, but you'll also mentor more junior engineers and shape the practices the rest of the team works by. If you like having real ownership, moving quickly without breaking things, and turning manual toil into automation, you'll fit right in.

This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec. You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer! We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow. Responsibilities:

Own the reliability of our production systems on GCP: define SLOs/SLIs, drive down incidents, and lead blameless postmortems.

Build the observability stack (Prometheus, Grafana, and related tooling) so we catch problems before customers do.

Design and maintain infrastructure as code with Terraform, no click-ops.

Operate and scale our Kubernetes / GKE workloads.

Build and harden CI/CD pipelines so teams can ship safely and often.

Relentlessly automate manual work; if it's done twice by hand, it's a candidate for automation.

Bake security into the platform: IAM, secrets management, network policy, and least-privilege by default.

Help us meet compliance requirements as we mature, and make the secure path the easy path for other engineers.

Own cloud cost visibility and efficiency: right-sizing, capacity planning, and scaling strategy as the company grows.

Requirements:

5+ years in infrastructure, SRE, DevOps, or platform engineering, including production ownership of cloud systems.

Strong hands-on experience with GCP.

Deep experience with Terraform.

Production experience running Kubernetes / GKE.

Proven track record building and maintaining CI/CD pipelines.

Solid grasp of observability practices and tooling (Prometheus, Grafana, etc.).

A bias toward automation and a security-conscious mindset.

The communication skills to mentor others and influence how the team works.

Nice to have :

Experience scaling infrastructure in a startup or high-growth environment.

Scripting/programming beyond config (Go, Python, etc.).

Service mesh, GitOps (e.g., ArgoCD/Flux), or progressive delivery experience.
