Aldesa is a leading global construction and infrastructure group headquartered in Madrid, specializing in civil engineering, building, renewable energy, and industrial projects. With over 50 years of history, the company has evolved into a major international player, particularly after becoming part of the China Railway Construction Corporation (CRCC) in 2020. It operates across several continents, managing complex large-scale projects ranging from high-speed rail networks to advanced data centers.

In Spain, Aldesa maintains a robust presence with offices and project sites distributed throughout the country, including Madrid, Barcelona, and Zaragoza. For international professionals, the company offers opportunities in highly specialized technical fields such as railway engineering, industrial installations, and renewable energy. Its integration into a global conglomerate like CRCC creates a multicultural environment where technical expertise is highly valued, often requiring coordination across international teams.

Founded in 1969 in Madrid, Aldesa grew into one of Spain's largest construction groups. In 2020, it underwent a significant transformation when China Railway Construction Corporation (CRCC) acquired a majority stake to expand its European and Latin American presence.
