Description du poste

Set a new pulse for healthcare!

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

Your mission will be to protect the infrastructure, identities, devices and platform that millions of patients and hundreds of thousands of health professionals rely on every day. You will work hands‑on across the full corporate IT security perimeter (identity, endpoint, SaaS, network and cloud) in a highly regulated environment (HDS, ISO 27001, C5) where security directly impacts patient safety and trust in the healthcare system.

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:

• Design and ship security changes as code, reviewed in pull requests like any production change, across our identity, endpoint, SaaS and network security stack
• Build detections, dashboards and automated responses on top of our SIEM (Elastic), writing queries and continuously tuning alert quality
• Drive corporate IT security programs from architecture to enforcement spanning Entra ID, CrowdStrike, Wiz, and Cloudflare
• Investigate security incidents end‑to‑end and iterate on playbooks with each resolution cycle
• Write proposals and run cross‑team change management on major security initiatives, ensuring robust communication with stakeholders
• Mentor junior engineers and contribute to platform security topics when initiatives span both the corporate and product perimeters

Who you are

Before you read on: if you don't have the exact profile described below, but you feel this job description matches your skill set, we still encourage you to apply.

You'll be a great fit if you:

• Have 5+ years of hands‑on experience in corporate, including at least 2 years at a senior level, with end‑to‑end ownership of multiple security domains (identity, endpoint, SaaS, network or detection) in production
• Have strong daily mastery of GitHub, Terraform and AI coding assistants (Claude or equivalent) — you ship security work as code reviewed in PRs, and you use AI agents as a structural part of your workflow, not as an occasional helper
• Have a solid detection engineering and SIEM background, and are comfortable writing queries and tuning alerts independently
• Bring a pragmatic mindset and strong written communication skills, with the ability to make decisions under uncertainty and follow through on complex, cross‑team initiatives
• Are fluent in English (primary written working language); daily team conversations happen mostly in French, so being a French speaker or willing to learn is a strong plus

It would be fantastic if you:

• Have curiosity for platform security topics (cloud, Kubernetes, supply chain) and a willingness to contribute beyond your core corporate IT perimeter
• Bring prior experience in a regulated industry such as healthcare, fintech or the public sector
