Deloitte is the world's largest professional services network, providing audit, consulting, financial advisory, risk advisory, tax, and legal services to many of the world's most prestigious brands. Operating as a global network of member firms, the company employs hundreds of thousands of professionals across more than 150 countries, serving as a dominant force in the global consulting and accounting industry.

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.

Founded by William Welch Deloitte in London in 1845, the firm grew through a series of high-profile mergers, including the 1989 merger with Touche Ross and the 1993 renaming to Deloitte Touche Tohmatsu. It has transitioned from a traditional accounting firm into a global leader in digital and strategic consulting.

For international professionals

Deloitte Spain operates over 20 offices across the country, providing diverse geographic options for relocation beyond just Madrid and Barcelona.
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.
Many technical and consulting roles in their 'Global Delivery Centers' in Spain prioritize English proficiency over Spanish fluency.
