About the role
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 to expand our battery pack assembly team, specifically a Battery Pack Engineering Lead. This is a hands-on technical leadership role. You'll take the line from a concept to a working, repeatable, and safe production line, leading things such as pack and module architecture, the assembly process, cell joining, thermal management, test, and safety. This role will anchor a small team of specialists and engineers, as well as interfacing cross-functionally with the rest of the company. You'll set technical direction, make the hard calls, and lead a few engineers alongside you.
What You'll Do Own the pilot battery pack assembly line end-to-end, from pack and module architecture through assembly process design, build, test, and production readiness Define the assembly process: cell intake and sorting/matching, module and pack build sequence, cell joining (laser / ultrasonic / resistance welding), busbar and interconnect assembly, thermal management, enclosure, and potting/sealing Develop the fixturing, stations, tooling, and work instructions for the pilot line, designed for eventual automation and rate production on Hadrian's robotics and software platform. Own battery safety including thermal runaway mitigation, abuse tolerance, and compliance with applicable standards and testing (e.g., UN 38.3 transport) Establish electrical test, formation, and characterization processes; define pack-level acceptance criteria and validation Build cell-level traceability and lot control, partnering with Quality and Qualification on inspection plans and qualification of the packs Lead and grow a small, deep-expertise team, setting technical direction and owning final calls Partner across design (mechanical/electrical/thermal), manufacturing engineering, automation/controls, supply chain (cell sourcing), quality/qualification, and program teams Drive the line from concept to production readiness against yield, throughput, cost, and rate targets
