AESC Tech Stack

Global battery manufacturer for EVs and grid energy storage

Manufacturing Yokohama, Kanagawa 10,001+ employees Public Company

AESC manufactures lithium-ion cells across multiple chemistries (LFP, NCM/MCA) and formats for automotive and stationary storage. With 14,000+ staff across six countries and a manufacturing footprint spanning Japan, US, UK, France, Spain, and China, the company is operationally complex—evidenced by heavy SAP/S/4HANA deployment, MES integration, and active work on job architecture standardization and scalable contracting. Engineering dominates hiring (22 of 53 active roles), reflecting the capital-intensity of cell-line construction and ramp-up; cited pain points cluster around downtime reduction, maintenance efficiency, and SAP implementation, signaling ongoing digital transformation across a legacy manufacturing base.
