Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

The Role

Hadrian's Physical Security team protects the people, factories and export-controlled work behind Hadrian's growth. As we open new factories and bring on new teams, every site needs a security leader on the ground, and the program needs people who help build it across all of our sites.

You will own security at our Torrance campus and be hands on every day: managing the contract security team, walking the site, and acting as the first call for any security risk. This is more than a walk-the-floor role. You'll also own a program area across every Hadrian site, such as investigations, workplace violence prevention, vendor management or security training, and help build a physical security program that keeps pace with the business.

You'll partner with site leadership, Facilities, EH&S, People and the Facility Security Officer, and report to the Director of Physical Security. This is an on-site role in Torrance, CA.

What You’ll Do

• Manage the contract security vendor at the site: set post orders and patrol plans, check the work against them, and hold the vendor to the contract.
• Walk the site regularly, find gaps in doors, openings and day-to-day security practice, rank them, and get them fixed.
• Lead the response to security incidents and site events as the first security leader on scene, and document them clearly.
• Keep site controls in place, including badge access, visitor management, key control, contractor escorts and controlled areas, in partnership with the Facility Security Officer.
• Build working relationships with local law enforcement, fire and other emergency services, and partner with site leadership, Facilities, EH&S and People.
• Own a program area across every Hadrian site, such as investigations, workplace violence prevention, vendor management, budget or security training.

What We’re Looking For

• 5+ years in corporate, industrial or government security, including time leading a site or a contract security team.
• Experience building or improving a security program, not only running a post or a site.
• Hands-on experience with access control, video and visitor management systems.
• Sound incident judgment and clear writing: incident reports, findings and post orders others can act on.
• Comfort working on a production floor and responding after hours when needed.
• Ability to hold vendors to a high standard while keeping a strong working relationship.

What Will Set You Apart

Background in intelligence, investigations, workplace violence prevention or security training.

Aerospace, defense or manufacturing experience.

Experience with export-controlled or other controlled environments.

Experience with California workplace violence prevention requirements (SB 553).

PSP or CPP certification.
