Thats quite the fork in the road. Mastering vs technical jobs at dolby /audio tech. For mastering you would be a "user" while at dolby you would be creating the systems or any arcilary jobs there.
I have a friend who did this audio program
(broken link removed)
then got hired to work in China for a speaker company . which is basically were all those tech jobs are nowadays. Dolby might be the few here or they mostly hire foriengers with very spcialized programming, math, science skills. of course thats generalizing a bit. Its not the same path as yours, but just showing another perspective. in china, product developement happens in weeks, as suppose to years in the US and many months in EU. So there is a lot of oportunities in the tech area. My friend was more like a liason between the US company and the tech ops over there.
as for mastering engineer, i know there are programs... but mastering engineer is not a job with a strong demand... it might be the other way around... way too many mastering engineers, not to mention Ozone 7
There is also the tech side of audio revolving around distribution. Companies like deluxe, tecnicolor, disney etc need very expensive equipment and specialized software from companies like digital rapids, amberfin, Clipster etc.
Those companies, like dolby, power the distirbution monster of hollywood but they are not as well known like dolby.
But trying to figure out atoms distribution, embedding surround, transcoding surround formats in cloud based platforms... all interesting stuff.
