About the role

Hadrian is expanding its battery pack assembly team to bring pilot line from concept to a safe, repeatable production line. Hands-on role partnering with the Battery Pack Engineering Lead to develop processes, fixturing, tooling, and testing for cells, modules, and packs.

Responsibilities

  • Develop, document, and improve assembly processes across the pilot line: cell intake and sorting/matching, module and pack build sequence, busbar and interconnect assembly, thermal interface application, enclosure, and potting/sealing
  • Support cell joining process development (laser / ultrasonic / resistance welding), including weld parameter development, qualification builds, and in-process verification
  • Design and build fixturing, stations, and tooling for the pilot line, with an eye toward eventual automation on Hadrian's robotics and software platform
  • Write and maintain clear work instructions, process control plans, and standard work for assembly operations
  • Support electrical test, formation, and characterization processes, and help define and execute pack-level acceptance testing
  • Implement cell-level traceability and lot control on the line, partnering with Quality on inspection plans and nonconformance dispositions
  • Run root cause and corrective action on process issues, yield losses, and equipment problems; drive improvements to yield, throughput, and cost
  • Support battery safety practices on the floor, including safe handling procedures, thermal runaway mitigation measures, and compliance testing activities (e.g., UN 38.3 transport)
  • Partner cross-functionally with design (mechanical/electrical/thermal), automation/controls, supply chain, quality/qualification, and program teams to move the line toward production readiness

Qualifications

  • Bachelor's degree in Electrical, Mechanical, Chemical, Materials, Manufacturing, or Industrial Engineering, or a related technical field
  • 2+ years of manufacturing or process engineering experience, ideally with hands-on exposure to battery pack or module assembly, energy storage, or another electro-mechanical assembly environment
  • Working knowledge of at least one cell joining or precision joining process (laser, ultrasonic, or resistance welding, or comparable processes)
  • Experience developing fixturing, tooling, or work instructions for assembly operations
  • Comfort working on the production floor: building, testing, breaking, and fixing things yourself
  • Strong problem-solving fundamentals, including structured root cause analysis and data-driven process improvement
  • Ability to operate with limited direction in a fast-moving, 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
