# Senior Security Engineer

⭐ About the role : At DataDome, security is a core part of how we build and scale. Our security team already covers GRC, SecOps, and security leadership, and we are now looking for a senior individual contributor to strengthen the engineering-facing side of the function. As DataDome evolves from a single product into a broader platform, our security scope is expanding across product, infrastructure, internal systems, and AI-enabled workflows. At the same time, our regulatory and assurance requirements are becoming more demanding, including ISO 27001 and SOC 2. We are looking for a Senior Security Engineer with a strong technical background, able to work closely with engineering teams and bring practical security expertise to product security, cloud security, application security, secure software supply chain, security tooling, and AI security topics. This role reports directly to the Head of Security. It is a pure individual contributor position with no management responsibilities. Impact comes from technical depth, hands-on execution, and cross-functional influence. You will be more specifically in charge of things like... Product, cloud, and application security Contribute to arc
