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.

Accountabilities:





• Validate and extend Secure SDLC threat models through continuous penetration testing, assessing threat severity, mitigation status, and underlying security assumptions.

• Automate routine security validations to keep pace with a rapidly evolving platform while reserving manual analysis for complex and high-impact scenarios.

• Plan and execute full-scope red team engagements across cloud compute, storage, inference, networking, orchestration layers, and internal tooling.

• Identify attack paths capable of impacting organizational operations, customer environments, or critical platform assets.

• Collaborate with detection and response and other security engineering teams on purple team exercises, validating detection coverage and closing defensive gaps.

• Research novel attacks against GPU infrastructure, including firmware, vendor drivers, device passthrough, SR-IOV/IOMMU configurations, and RDMA/InfiniBand environments.
