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
What We're Looking For
Bachelor's degree or higher in Electrical, Mechanical, Chemical, or Materials Engineering, or a related technical field
7+ years in battery pack / energy-storage engineering, including hands-on pack or module assembly and manufacturing
Deep knowledge of cell-to-pack / cell-to-module design and assembly, cell joining (welding) processes, and thermal management
Experience standing up or significantly improving a battery assembly line or pilot line
Strong grasp of battery safety and applicable standards/testing (UN 38.3, UL/IEC, abuse testing)
Demonstrated technical leadership, able to lead a small team and operate autonomously in an ambiguous, build-it-now environment
Must be a U.S. Person (U.S. citizen or lawful permanent resident) per ITAR; ability to obtain and maintain a U.S. security clearance
What Will Set You Apart
Battery pack experience in aerospace, defense, UAS, eVTOL, EV, or other demanding/safety-critical applications
Experience automating battery assembly or designing battery lines for high-rate production
Hands-on cell-joining process development (laser / ultrasonic / resistance welding) for tabs and busbars
Electronics and test-and-validation depth
Familiarity with defense qualification or airworthiness requirements for energy storage
Experience in high-growth or startup manufacturing environments
Benefits for Full-time Employees
Medical, dental, vision, and life insurance plans for employees
401k
Relocation support may be provided for certain situations, based on business need.
Flexible vacation policy
Equity
ITAR Requirements
