CESI SpA Tech Stack

Engineering and testing services for power systems and energy infrastructure

Engineering Services Milan, Italy 501–1,000 employees Founded 1956 Privately Held

CESI is a 70-year-old engineering firm built around power-systems testing, grid modernization, and energy-transition consulting. The tech stack reflects deep domain specialization: power-flow simulators (PSS/E, DIgSILENT PowerFactory), CAD/BIM for infrastructure design, and industrial tools (SCADA, Maximo) for asset management. Engineering dominance in hiring (44 of 51 open roles) and active projects centered on high-voltage test-setup design signal a company scaling hands-on lab and field operations rather than shifting toward software products.
