The role

We are looking for a Site Security Manager to lead physical security operations for the   Nebius   San Francisco office. You will own the day-to-day security posture of the site, protect employees, visitors,   assets   and infrastructure, and make sure local practices are robust,   compliant   and aligned with Nebius corporate standards. This is a hands-on leadership role for someone who can set clear processes, manage vendors and front-desk security personnel, and respond calmly and decisively when incidents occur.   You will be the local owner of physical security: the person who turns standards into daily practice, protects people and assets, and keeps the site ready for both routine operations and unexpected events.  

Your responsibilities will include:  

Lead day-to-day physical security operations at the Nebius  San Francisco office,  maintaining  a safe,  secure  and professional environment for employees,  visitors  and company assets.  

Develop, implement  and continuously improve site-specific security policies, procedures and training for the San Francisco office, aligned with Nebius corporate standards and applicable U.S.,  California  and San Francisco requirements.  

Monitor and manage CCTV, alarm systems and access-control processes, ensuring reliable operation, clear escalation routes  and  timely  response to potential threats.  

Conduct regular risk assessments, site reviews  and  physical-security  checks;  identify  vulnerabilities and drive corrective actions to completion.  

Serve as the primary local liaison with local law enforcement, emergency services, building management and other relevant authorities during incidents, emergencies  or crises.  

Lead investigations into security breaches and incidents, document findings clearly, and implement corrective and preventive actions.

Manage relationships with external security vendors and contractors, setting expectations and ensuring high-quality service delivery.

Direct, brief and coach front-desk security personnel on-site so that security standards are applied consistently and professionally.

Partner with Facilities, IT, People, Legal/ Compliance and site leadership to keep local practices aligned with company-wide security,  safety  and business-continuity expectations.  

How you will make an impact:

Build a site-security operation that is disciplined, reliable  and easy for employees and visitors to navigate.  

Raise risks early, communicate clearly and help the business move quickly without compromising safety or control.

Create a strong local security culture through visible leadership, practical training  and consistent standards.  

We expect you to have:  

Proven experience managing physical security operations, preferably in large corporate , technology,  critical-infrastructure  or governmental environments.  

Strong leadership, communication  and interpersonal skills, with the ability to manage vendors,  contractors  and diverse on-site teams.  

Solid knowledge of physical-security principles, risk management, emergency response and applicable U.S., California  and San Francisco requirements.  

Hands-on experience with security technologies, including surveillance systems, CCTV, alarm systems  and access-control platforms.  

Excellent analytical and problem-solving ability, with the judgment to assess risk, prioritize remediation and implement effective solutions.

Calm, credible decision-making under pressure, especially during emergencies, incidents  or sensitive investigations.  

Clear documentation and reporting skills, including incident reports, risk summaries, findings  and  corrective-action  plans.
