Westlake Tech Stack

Global chemical manufacturer and materials supplier for packaging, automotive, and construction

Chemical Manufacturing Houston, Texas 10,001+ employees Founded 1986 Public Company

Westlake is a large, publicly traded chemical manufacturer operating across olefins, vinyls, polymers, and building products with ~16,000 employees across North America, Europe, and Asia. The tech stack reveals a heavily operationalized business: SAP + JD Edwards for ERP, OSIsoft PI + LIMS for production monitoring, Kinaxis for supply-chain planning, and Workday for HR — the backbone of a mature, process-driven organization. Active hiring across manufacturing, engineering, and operations (slowing from peak) aligns with concurrent lean manufacturing and preventative maintenance programs, suggesting post-acquisition integration or capacity optimization rather than expansion.
