Stemac Tech Stack

Diesel and gas generator manufacturer with national distribution across Brazil

Machinery Manufacturing Porto Alegre, Rio Grande do Sul 1,001–5,000 employees Founded 1951 Privately Held

Stemac manufactures and sells generator groups across Brazil through 38 regional branches, competing on service depth (project design through post-sale support) rather than pure manufacturing scale. The tech stack is CAD-heavy (AutoCAD, DraftSight, TwinCAT, PLC, CNC) with SAP for operations—typical for industrial OEMs—but hiring velocity is accelerating with a sales-led staffing mix (15 sales roles open vs. 7 engineering), suggesting geographic expansion or channel growth rather than product innovation.
