Manufacturing Engineer, Battery Assembly

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 expanding our battery pack assembly team and is looking for a Manufacturing Engineer to help bring our pilot battery pack assembly line from concept to a working, repeatable, and safe production line. This is a hands-on role. Working alongside the Battery Pack Engineering Lead and a small team of specialists, you'll develop and refine the processes, fixturing, and tooling that turn cells into qualified packs. You'll get deep exposure to pack and module assembly, cell joining, thermal management, test, and safety, with room to grow your ownership as the line scales.

WHAT YOU'LL DO

- Develop, document, and improve assembly processes across the pilot line: cell intake and sorting/matching, module and pack build sequence, busbar and interconnect assembly, thermal interface application, enclosure, and potting/sealing

- Support cell joining process development (laser / ultrasonic / resistance welding), including weld parameter development, qualification builds, and in-process verification

- Design and build fixturi...
