Mistral; Paris; Hybride; EUR 90 000 - 130 000; Plein temps

Résumé du poste

Mistral is seeking a Platform Security Engineer to architect and maintain the security posture of our rapidly scaling AI infrastructure and lifecycle. You will embed robust controls into CI/CD, cloud environments, and developer workflows to protect systems without slowing velocity.

You will shape security integration across the stack, from code to cloud, making secure practices automatic by default and transparent to researchers and engineers.

Qualifications

• Five or more years of experience in Platform Security, Security Engineering, or Cloud Security, ideally as an early security hire in a fast-scaling environment.
• Deep understanding of container orchestration and container security, alongside strong experience securing Infrastructure-as-Code across major cloud providers.
• Strong programming and scripting skills in languages such as Python or Go to build security automation and integrate diverse security tools into developer workflows.

Responsabilités

• Drive threat modeling and risk prioritization exercises as the security counterpart in system-design reviews for core infrastructure and new products.
• Own end-to-end vulnerability management across CI/CD pipelines and runtime environments, covering infrastructure and applications.
• Secure our container orchestration deployments and containerized workloads, implementing advanced hardening to prevent lateral movement across distributed systems.
• Define and enforce Infrastructure-as-Code security by building robust guardrails and integrating policy-as-code into deployment pipelines.
• Design and execute a comprehensive security tooling strategy, managing solutions for cloud-native application protection, cloud security posture, static code analysis, dependency scanning, secrets management, and vulnerability tracking.
• Champion developer enablement by building secure defaults, streamlining remediation workflows, and drafting actionable security guidelines.
• Build foundational security automation to scale alongside hyper-growth, minimizing manual overhead while establishing a pragmatic security culture.
