You will design and implement how physical office security works at Nscale from the ground up, with responsibility for keeping employees, visitors, and corporate spaces safe as our footprint expands.

• Build onboarding and offboarding controls tied to physical access.
• Ensure security processes support productivity and culture in a fast-moving environment.

Contractors & External Partners

• Select, onboard, and manage security vendors and facilities-related contractors globally.
• Work with landlords, building management, and local authorities as required.
• Set expectations and standards for third parties supporting corporate security.

Incident Response & Risk Management

• Own response to physical security incidents affecting corporate offices or staff.
• Build incident response playbooks and post-incident review processes.
• Regularly assess risks to people and workplaces and implement improvements as the business scales.

About You

• 5+ years owning or leading corporate or workplace security in a growing organisation.
• Proven ability to build security programs, processes, and controls where little previously existed.
• Strong understanding of physical security, access control, workplace safety, and vendor management.
• Experience operating across multiple regions or supporting global office footprints.
• Comfortable making decisions in ambiguous, high-growth environments.
• Practical, credible, and calm—able to influence both senior leaders and employees.
