Offensive Security Engineer

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

Join a hands-on offensive security team working at the frontier of cloud infrastructure and AI. In this role, you’ll simulate sophisticated attacks against the same systems customers rely on, helping uncover weaknesses before they can become real threats. You’ll contribute across cloud compute, storage, networking, inference, orchestration, and internal tooling while helping establish a scalable penetration testing and red team program. The role combines practical adversarial operations with security research into emerging GPU and AI infrastructure attack surfaces. You’ll work closely with detection and security engineering teams to validate defenses and turn findings into measurable improvements. With substantial technical ownership, you’ll have the opportunity to influence security practices across a rapidly evolving, large-scale AI platform.
