Senior Security Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Security Engineer based in France.

This role sits at the core of securing a complex, cloud-native cybersecurity platform used by enterprises and government organizations to detect and respond to real-world adversary activity. You will take full ownership of application and cloud security across a fast-moving engineering environment, directly shaping how security is embedded into products, infrastructure, and delivery pipelines. The position is highly hands-on, focused on building, implementing, and improving security controls rather than advising from the sidelines. You will work closely with engineering, DevOps, and product teams to ensure secure design, resilient architecture, and effective threat detection across AWS and Kubernetes environments. In addition, you will play a key role in compliance programs such as SOC 2 and ISO 27001 while supporting customer trust and audit processes. This is a leadership role with direct responsibility for mentoring a security engineer and acting as a technical escalation point for security incidents. The environment is fast-paced, mission-driven, and highly collaborative.
