About this role
Scale AI sits at the intersection of frontier AI, enterprise software, and national security. We safeguard high-value assets: proprietary AI data and infrastructure, a global contributor ecosystem, and sensitive enterprise and government customer data.
As our International Head of Security, you will own and unify Scale’s security strategy across our non-US affairs: Global Public Sector and non-US Enterprise deals. You will drive the execution, customer engagements and compliance with frameworks such as GDPR, ISO27001, UK Cyber Essentials Plus, the EU AI Act, NIS2 and country-specific sovereignty requirements while staying tightly aligned to our global secure-by-default architecture set by the Head of Security.
As we expand into FDE-led Agentic Applications while continuing to serve our data and model customers, our security surface area spans internal systems, external products, distributed contributors, and high-assurance government environments. You are a builder who believes security is a product feature, not a hurdle — and who can raise both our defensive maturity and our ambition in frontier AI security.
What You'll Do
Execute the Global Security Strategy Across International Markets
• Drive execution of Scale's multi-year secure-by-default roadmap across non-US markets, surfacing regional needs into global architecture decisions.
• Translate regional regulatory requirements (GDPR, ISO 27001/27017/27018, SOC 2, UK Cyber Essentials Plus, EU AI Act, NIS2, and country-specific data residency / sovereign-cloud rules) into concrete engineering controls.
• Track regional security metrics and accountability, and represent the international perspective in global prioritisation, audits, and roadmap reviews.
Lead Regional Security Engineering & Threat Detection
• Own the regional execution of identity, fine-grained RBAC, secrets management, CI/CD hardening, encryption, logging, and infrastructure protection with a particular focus on cross-border data flows and in-region telemetry.
• Stand up high-fidelity detection and response capabilities that meet local time zone coverage, breach-notification timelines, and regulator expectations.
• Drive systemic risk reduction through platform-level controls, partnering with the global security engineering team rather than building parallel stacks.
Secure Products, Data, and AI Systems for International Customers
• Ensure enterprise-grade protection of customer data, proprietary datasets, and AI assets across regional deployments, including support for in-region processing, encryption with customer-managed keys, and data-localisation commitments.
• Design and enforce robust multi-tenant isolation, fine-grained RBAC, and privilege lifecycle management across customer environments serving international enterprises and public sector buyers.
• Address AI-specific attack surfaces; prompt injection, tool abuse in agentic workflows, data exfiltration, and model/data integrity risks.
