In Spain, Deloitte maintains a massive presence with a network of offices spanning the entire country, including major hubs in Madrid and Barcelona. The firm is a significant recruiter of international talent, particularly within its technology, cybersecurity, and digital transformation divisions, where English is often the primary working language and multicultural teams are the norm.

It has transitioned from a traditional accounting firm into a global leader in digital and strategic consulting.

The company is a major sponsor of work visas for highly skilled international profiles, particularly in specialized IT and financial roles.
They offer a structured 'International Mobility' framework that supports employees moving between global member firms.
Deloitte University EMEA provides extensive continuous learning and networking opportunities for professionals looking to advance their careers in Europe.
