Platform Security Engineer (x/f/m)

Set a new pulse for healthcare!

We are looking for a Platform Security Engineer to join the Security team at Doctolib.

Your mission will be to protect sensitive healthcare data while enabling rapid, secure innovation. You will be responsible for securing Doctolib's cloud infrastructure and application ecosystem, combining multi-cloud security expertise with hands-on platform engineering — contributing directly to the safety of millions of patients and care teams who rely on our platform every day.

Working in the tech team at Doctolib means building innovative products and features to improve the daily lives of care teams and patients.

What you'll do

Your responsibilities include but are not limited to

• Own a platform security workstream end to end, from architecture to enforcement: scope it with your tech lead, design the control, roll it out progressively (report-only, then enforce), handle exceptions, and see it through to full coverage. Typical examples: hardening IAM across our AWS accounts, tightening cluster admission policies, or closing a class of misconfiguration for good.
• Ship every change as code: Terraform and GitHub pull requests, peer-reviewed and always reversible. No console clicking, no undocumented state.
• Harden our cloud and infrastructure baseline and keep it hardened: IAM permissions and access reviews, secrets management, network and cluster guardrails, CI/CD and supply chain controls — building the guardrails and driving remediation of what they surface with platform and engineering teams, turning recurring findings into automation rather than tickets.
