Battery Pack Engineering Lead

The Role

Hadrian is looking to expand its 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
• 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

• 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

• To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
