Mistral AI is a technology company that develops and provides AI-powered solutions and platforms for enterprise use. Our technology is designed to integrate seamlessly into daily working life.

Role Summary

As a CyberSecurity Team Lead, you will be responsible for architecting and enforcing the security posture of our entire technical stack, from on-premise foundations to cloud-native deployments. You will oversee the identification, prioritization, and remediation of vulnerabilities across both On-Prem and Cloud infrastructures as well as internal applications.

Responsibilities

• Oversee the identification, prioritization, and remediation of vulnerabilities across both On-Prem and Cloud infrastructures as well as internal applications.
• Select, deploy, and maintain the tools needed for visibility and protection, including CNAPP, CSPM, SAST/DAST, secret scanning, and SBOM/CVE tracking.
• Integrate security controls and automated gates directly into CI/CD pipelines to catch vulnerabilities before deployment (Shift Left).
• Partner with engineering teams to interpret findings and 'ease the fix,' providing patches, code snippets, or architectural advice to resolve issues quickly.
• Define and maintain rigorous security guidelines and best practices for developers and system administrators.
• Design and lead security awareness programs and technical training tailored for developers and admins to reduce human risk.
• Track and define key security metrics (MTTR, coverage, vulnerability density) to visualize posture and progress to leadership.

Requirements

• 6+ years of experience in Information Security, with a specific focus on Application Security, Cloud Security, or DevSecOps.
• Strong scripting skills (Python, Go, or Bash) to automate security tasks and integrate tools.
• Deep understanding of CI/CD ecosystems and container orchestration (Kubernetes/Docker).
• Hands-on experience with modern security tooling (e.g., Wiz, Snyk, SonarQube, Prisma, or similar enterprise tools).
• Collaborative mindset: you view developers as partners, not adversaries, and focus on enabling them to code securely.
• Clear communication, autonomous, and capable of translating technical security risks into actionable engineering tasks.

Benefits

• Competitive salary
• Comprehensive health insurance
• Flexible working hours
• Professional development opportunities
