Head of Information Security at Constructor Tech in France

About the Role

We're looking for a Head of Cybersecurity to expand and lead our security function across four areas: application security, security compliance, infrastructure & cloud security, and business application security. You'll take over a small existing security team, with a mandate to grow it as the company scales.

This is a hands-on leadership role. You'll set direction and represent security to leadership, but you're also expected to dig into technical detail with engineering, IT, and compliance teams.

Duties & Responsibilities

Application security

• Build and run our AppSec program, including agentic/AI-assisted security reviews of code and pull requests
• Integrate security checks into CI/CD pipelines so vulnerabilities are caught before production
• Run developer security training and champion secure coding practices org-wide
• Evaluate and roll out AI coding tools in ways that improve, not undermine, code security

Security compliance

• Own ISO 27001 and SOC 2 certification and ongoing security audits
• Collect requirements from stakeholders and build a roadmap for additional certifications as the business requires them
• Maintain policies, controls, and evidence in a way that scales without slowing teams down

Infrastructure & Cloud Security

• Work closely with our DevOps organization to secure our Kubernetes infrastructure and cloud environments, including sovereign cloud deployments
• Define security standards for infrastructure-as-code, network architecture, and access control
• Partner with Engineering teams on secure-by-default configurations

Business Application Security

• Work closely with IT and Business application teams to secure Microsoft 365 and other line-of-business systems, including CRM and ERP
• Own identity, access, and data protection controls across business applications
• Manage third-party/vendor risk for business-critical SaaS

Qualifications & Experience:

• 8+ years in information security, including 3+ years in a leadership role, preferably in all-remote or hybrid international organizations
• Track record running application security programs, ideally with CI/CD-integrated tooling and modern (AI-assisted) code review
• Hands-on experience with ISO 27001 and/or SOC 2, proven experience leading and successfully completing the audit, not just reading the standard
• Experience securing business applications (M365, CRM, ERP) and vendor risk management
• Ability to explain risk and trade-offs clearly to both engineers and executives
• Comfortable operating with a small team and prioritizing across competing demands
• Working knowledge of Kubernetes and cloud security; sovereign cloud experience is a plus
