Descripción de la vacante

EY is seeking a security leader for Challenger Core to embed security in AI lifecycles, protect data, and design reusable controls for safe AI use cases. You will collaborate with product and engineering teams, develop threat models, and drive pragmatic, secure patterns across deployments.

The role emphasizes hands-on automation, adversarial testing, and responsible risk guidance, with travel up to 50% and a hybrid office presence across US locations.

Formación

• 5+ years of relevant experience.
• Bachelor’s Degree in a relevant field.
• Substantial experience in product, application, cloud, platform, or detection security, including hands-on ownership of production controls.
• Threat modeling: ability to assess complex systems and turn attack paths into practical engineering measures.
• Production security: securing modern applications, cloud environments, identities, data, networks, and pipelines.
• AI systems knowledge: working understanding of generative and agentic AI, including retrieval, model access, tool use, evaluation, and runtime behavior.
• Hands-on automation: building or extending security tests, controls, telemetry, reference implementations, or adversarial assessments.
• Response experience: supporting vulnerability or incident response and translating lessons into stronger technical controls.
• Cross-functional delivery: partnering with engineers and risk functions to improve security while respecting user value and delivery constraints.
• Travel and On-site requirements: up to 50% travel and hybrid office presence.

Responsabilidades

• Set the security direction. Own reusable AI security patterns, control objectives, reference architectures, and threat models.
• Join builders early. Work with teams before key design choices are fixed, identifying credible attack paths and shaping controls.
• Design scoped authority. Create practical patterns for identity, access, isolation, approvals, and recovery.
• Protect sensitive information. Embed security across the data lifecycle, preserving confidentiality, integrity, provenance, permitted use, and monitored access.
• Secure the delivery path. Integrate automated security tests, policy gates, trusted artifacts, traceable changes, and safe rollback.
• Test adversarially. Run red-team exercises against AI abuse cases and turn findings into repeatable tests and stronger patterns.
• Build runtime protection. Use evidence and signals to detect abnormal actions and privilege misuse.
• Strengthen response. Support vulnerability triage and incidents with evidence and recovery actions.
• Advise on residual risk. Provide concise technical recommendations while keeping risk decisions with owners.
• Build shared capability. Create reference implementations and coach engineers to reuse controls.
