Lead threat modelling and risk assessment efforts for Meta's most complex systems, developing novel approaches to address systemic vulnerabilities across the company
Architect and implement engineered security controls, guardrails, and defence-in-depth mechanisms that enable product teams to move fast while managing risk responsibly
Partner with senior leadership across multiple organisations to define pillar-level security goals, influence roadmaps, and drive accountability for execution across cross‑functional teams
Identify capability and tooling gaps across the pillar's security stack and drive technical solutions that achieve scale, automation, and measurable risk reduction

Experience with system design, threat modelling, and risk assessment across complex, multi‑layered infrastructure and product environments
Experience building engineered security controls and guardrails applying principles such as least privilege, defence in depth, and segmentation
Experience communicating complex security risk and technical decisions in writing to both technical and non‑technical stakeholders, including senior leadership
Preferred Qualifications:
Experience influencing the external security community through published research, conference presentations, or open‑source contributions
Experience adhering to and implementing responsible, ethical AI practices including risk assessment, bias mitigation, and validation of AI‑generated outputs in security contexts
Demonstrated ability to integrate AI tools to redesign security workflows and drive measurable impact such as efficiency gains or improved threat detection quality
Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
