Battery Pack Engineering Lead
$220,000–$280,000 year
On-siteLos Angeles, California, United States
Job Summary
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 including cell intake, module build sequence, cell joining via laser/ultrasonic/welding, thermal management, and enclosure potting. Develop fixturing, stations, tooling, and work instructions designed for eventual automation on Hadrian's robotics platform. Own battery safety, thermal runaway mitigation, and compliance with standards like UN 38.3. Establish electrical test and characterization processes while building cell-level traceability and partnering with Quality on inspection plans. Lead a small team of specialists, setting technical direction and making final calls across design, manufacturing, automation, and supply chain functions. Drive the line from concept to production readiness against yield, throughput, cost, and rate targets.
Required Qualifications
- 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
