Why we choose open source

Open source is Red Hat’s origin story. It’s how we came to be. We’re an enterprise company with an open source development model, and we believe working in the open is the best way to work for the larger open source community and for technological innovation as a whole.

Open source principles guide how we create software and how we work across the company. Red Hatters are encouraged to contribute to problem solving, no matter their role or experience level. This ensures that the best ideas—the ones that creatively address our customers’ challenges—are heard and implemented, leading to better decisions for our business and customers.

Opportunities are open

We’re looking for creative problem solvers who have the courage to innovate. We need people who share our belief that we can do more by working together openly.
