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 is looking for a Maintenance Engineer to build and scale the systems that drive machine reliability, uptime, and maintenance execution across our factories. This role is closest to a manufacturing engineer focused on maintenance, and will own the content, scheduling, and process behind preventative, reactive, and predictive maintenance.

They will work closely with Factory Technicians and Leads, Supply Chain, Maintenance Specialists and Technicians, Production Scheduling, and Factory Development.

This is a high-ownership role for someone excited to build a process from the ground up using modern tools and systems. The right candidate will help lay the foundation for how Hadrian manages preventative and predictive maintenance, and can influence procurement, CMMS development, and future machine selection as the company scales.
