Vantaggi
In the past couple of years since I've joined, the company has made big changes in executive leadership (new CEO and new CTO). In that time, Sabre has also made big changes to the business (going public, moving Travelocity to Expedia's platform, attempting to sell lastminute.com). Internally, we are pushing to change the culture to be "one Sabre" and to drive innovation. Common topics: creating big data products, shifting to cloud architectures, focusing on world class user experiences. As a software developer, it feels pretty positive. You are definitely rewarded for pushing your product forward.
Svantaggi
Culturally, there seems to be a lot of apathy. Technology seems to be about 5-10 years behind the best tech companies. For example, we're just now starting to investigate cloud architecture. If you're into mainstream technologies from 5 years ago, you're considered leading edge rebels.
