LESER GmbH & Co. KG Tech Stack

Industrial safety valves and overpressure protection systems for process equipment

Mechanical Or Industrial Engineering Hamburg, Hamburg 1,001–5,000 employees Founded 1818 Privately Held

LESER manufactures safety valves and overpressure protection components for industrial machinery and equipment. The company's tech stack is almost entirely SAP-based (R/3, S/4HANA, EWM, Controlling), with Excel and Office supporting operations—a pattern typical of mid-sized industrial manufacturers managing complex supply chains and production. Current hiring is intern-heavy (7 of 13 roles) across engineering and operations, suggesting either a training program or temporary capacity building; ongoing projects in standardization, cost accounting, and supplier performance improvement indicate LESER is in the midst of operational modernization rather than product innovation.
