About this role

At Harbinger Motors, this role puts you at the center of battery manufacturing operations for a startup building medium-duty electric vehicles. You'll own daily production problem-solving—from resolving quality and safety issues to driving continuous improvement across throughput, yield, and cost. The position demands someone who can wear multiple hats: troubleshooting manufacturing bottlenecks, leading root cause investigations, training technicians on updated procedures, and supporting engineering changes and new product launches. You'll work cross-functionally with Operations, Quality, Supply Chain, and Product Engineering to keep production running smoothly while optimizing processes using Lean and Six Sigma methodologies.

This is a fit for engineers with at least three years in battery manufacturing, particularly cell-to-module and module-to-pack integration work. You should be comfortable with hazardous materials handling in high-voltage battery environments and proficient in MES, ERP systems, and manufacturing data analysis. Strong communication and the ability to lead across functions matter as much as technical depth. The role is based in Garden Grove, CA and requires in-office presence.

Harbinger offers competitive benefits including full health, dental, and vision coverage, early-stage stock options, 401k with HSA/FSA options, generous PTO and parental leave, and complimentary meals. The salary range is $100,000 to $150,000.
