Battery Pack Engineering Lead

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 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…
