All the engineering teams I've worked with are fairly forward thinking in both process and technology. Most teams use the hosted, enterprise GitHub for source control. There are a bunch of technical problems across the company spanning everything from researching photo/video manipulation, open source projects like Brackets, to a bunch of cool stuff going on as part of the Creative Cloud (or even analytics/big data in the Digital Marketing part of the company).
The company will definitely be around in 3 years and is on a good trajectory. A lot of teams have an unofficial work from home day every week, and while "main" HQ is in San Jose, a lot of fun stuff is going on in the SF office. In general I've found it to be a great culture in terms of work-life balance as well as encouraging volunteer activities.
