Descripción de la vacante

Doctolib is seeking a Platform Security Engineer to protect cloud infrastructure and app ecosystems while enabling rapid, secure innovation. You will own security workstreams end‑to‑end, enforce guardrails, and drive remediation with platform and engineering teams.

You’ll work with Terraform, GitHub PRs, and Kubernetes, improving IAM, secrets management, and detections. Fluency in English is expected; French is a plus, with a hybrid office setup in Levallois-Perret, France.

Formación

• 1–3 years of hands-on experience in security engineering, security operations, SRE, or platform engineering in production cloud environments.
• Hands-on with Terraform through reviewed pull requests; comfortable operating and debugging workloads on Kubernetes.
• Familiar with English; willingness to work in a bilingual team (French is a plus).
• Have delivered at least one project to production and driven adoption beyond initial deployment.

Responsabilidades

• Own a platform security workstream end‑to‑end from architecture to enforcement, including IAM hardening and policy controls.
• Ship changes as code with Terraform and GitHub PRs; ensure reversibility and no undocumented state.
• Harden cloud baseline, manage secrets, network guardrails, CI/CD controls, and remediation automation.
