Senior Security Manager

What you’ll do

• Own Giga’s physical security program end to end across the Houston HQ and field sites, including physical access controls, monitoring, visitor management, and secure storage of assets and media.
• Administer physical access to facilities, ensuring access is granted based on least privilege and promptly removed when personnel are terminated or change roles.
• Run visitor management, including authorization, escorting, and logging of visitors to company facilities.
• Maintain physical monitoring and surveillance mechanisms and ensure they remain operational and effective at deterring and detecting unauthorized access.
• Conduct periodic reviews of physical access to validate that access remains appropriate, and document and implement any resulting changes.
• Oversee secure storage and handling of sensitive media, equipment, and other assets, restricting access to authorized personnel.
• Own and maintain physical security policies and procedures, keeping them current as the business and site footprint grow.
• Plan and execute regular site visits and physical security assessments to identify gaps, drive remediation, and verify controls are operating as designed.
• Assess and monitor external physical security threats to Giga’s sites and personnel, and coordinate with site leadership, vendors, and local law enforcement to mitigate risks to facilities and people in the field.
• Develop and maintain site security plans and incident response procedures for facilities, including protocols for protests, trespassing, or threats during construction and operation.
• Collect, organize, and maintain audit evidence for physical security controls within the company’s GRC platform, and serve as the physical-controls point of contact during SOC 2 and ISO audits.
• Manage physical security vendors and contractors (guard services, monitoring, badge and access systems), holding them to Giga’s standards.
• Respond to, investigate, and document physical security incidents, and partner with the CISO on the physical components of the broader security and risk program.

Requirements

• 5+ years of experience in physical/corporate security, security operations, or a closely related compliance-facing role.
• Experience with, or the aptitude to quickly learn, GRC platforms (Drata, Vanta, OneTrust, or similar) to collect and manage control evidence.
• Working knowledge of SOC 2 and ISO 27001 compliance frameworks, particularly the physical and environmental security and access control domains.
• Practical physical security background: badge/access systems, surveillance, visitor management, and facility access controls.
• Strong documentation and organizational skills; you can turn a walkthrough into clean, audit-ready evidence.
• Excellent written and verbal communication; able to work with site teams, vendors, and executives alike.
• Comfortable operating in ambiguous, fast-moving environments where the process may not exist yet; you build it.
• Based in or willing to relocate to Houston, and willing to travel regularly to sites (~30%).

Bonus Points

• Direct experience preparing for or supporting a SOC 2 Type II audit.
• Hands-on experience administering Drata specifically.
• Industry certifications such as ASIS PSP/CPP, Security+, or an ISO 27001 Lead Implementer/Auditor credential.
• Experience securing industrial, energy, data center, or other critical-infrastructure sites (vs. office-only environments).
• Familiarity with additional frameworks (NIST, ISO 27701) or environmental controls (fire suppression, HVAC, power) relevant to in-scope facilities.
• Experience managing guard services or physical security vendor relationships.
• A hands-on, get-it-done approach; comfortable in the field, not just behind a desk.

Who we hire

• We hire people who thrive in chaos and get sharper under pressure. You don't wait to be told what to do, you spot the gap and fill it. When there's work to be done, you do it. You make decisions with the information you have, move fast, and adjust along the way. We're not looking for perfect; we're looking for people who get things done.
