About the role

  • This role sits at the intersection of electrical, mechanical, and controls disciplines.

Responsibilities

  • Develop and document manufacturing processes, assembly sequences, and standard work instructions for BESS enclosures, DC subsystems, power conversion systems (PCS), and medium-voltage UPS/microgrid assemblies.
  • Lead Design for Manufacturing and Assembly (DFMA) reviews with product and design engineering to improve manufacturability, reduce part count, and drive down cost before designs are released.
  • Define and validate station-level requirements: workstations, tooling, fixtures, torque and crimp specs, cabling and busbar routing, and material flow across the line.
  • Partner with contract manufacturers on process transfer, first-article inspection (FAI), production ramp, and ongoing process control
  • Drive root-cause analysis (8D, 5-Why, fishbone) on quality escapes and line stoppages, and implement corrective/preventive actions.
  • Lead continuous-improvement initiatives using Lean and Six Sigma methods (value-stream mapping, kaizen, SPC) to improve yield, throughput, and cost per unit.
  • Own engineering change management (ECN/ECO) from the manufacturing side, including bill-of-material (BOM) accuracy, routings, and configuration control in the ERP/PLM system.
  • Support production capacity planning, line balancing, and takt-time analysis to meet build schedules.
  • Champion a safety-first culture on the floor: LOTO, arc-flash and high-voltage/medium-voltage safe work practices, and ergonomic workstation design.

Requirements

  • Bachelor's degree in Mechanical, Electrical, Manufacturing, or Industrial Engineering (or equivalent experience).
  • Proficiency with DFMA principles, GD&T, and reading electrical schematics and mechanical drawings.
  • Experience creating work instructions, process FMEAs, control plans, and test procedures.
  • Experience working in an ERP/PLM environment (e.g., SAP, Oracle, Arena, Windchill) for BOMs, routings, and change control.
  • Strong problem-solving skills, disciplined documentation habits, and the ability to work cross-functionally across engineering, quality, supply chain, and operations.

Nice to have

  • Experience with battery module/pack integration, BMS interfaces, and thermal management.
  • Experience with medium-voltage equipment and microgrid or UPS integration.
  • Knowledge of relevant standards: UL 9540 / UL 9540A, UL 1741, IEC 62933, NFPA 70/70E, and applicable UPS standards (e.g., UL 1778 / IEC 62040).
  • Experience standing up a new production line or transferring a product to a contract manufacturer.
  • Familiarity with test automation, data acquisition (e.g., LabVIEW), and EOL test system development.
