Leidos is a Fortune 500 science and technology company founded in 1969, employing approximately 47,000 people worldwide. It provides digital and mission solutions to government and commercial customers, with principal focus areas in national security and health.
The company's work spans a broad range of technical disciplines, including cybersecurity, defence systems, intelligence, and health technology. Its customers are primarily government agencies, though it also serves commercial clients. Over more than five decades, Leidos has grown through both organic expansion and acquisition into one of the larger publicly traded defence and technology contractors in the United States.
Leidos traces its origins to an emphasis on employee ownership and a founding vision of applying scientific expertise to complex national problems. That orientation toward technical rigour and mission-critical work continues to shape how the company is structured and staffed, with a strong premium placed on engineering and scientific capability across its teams.
