Hadrian - Manufacturing the Future

Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts.

We’re accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts.

Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.

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.

This person will be responsible for developing and optimizing our maintenance execution process and strategy, with direct impact on machine uptime, repair costs, and the processes executed by dozens of operators. 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.
