Co-founded by Javier Diaz, OSI Engineering has grown into one of Silicon Valley’s most respected technology workforce solutions firms, providing engineering, software development, artificial intelligence, and technology talent to some of the world’s most recognized companies. What began as an entrepreneurial vision has evolved into a company recognized for both business excellence and community impact.

For Javier Diaz, the journey began far from Silicon Valley’s boardrooms and technology campuses. Raised in the farming community of Gridley, California, he learned the values of hard work, perseverance, and determination at an early age. Those lessons would become the foundation for building a company capable of competing in one of the world’s most demanding and innovative business environments.
