You would have to add this in yourself. You can include it anywhere in the file, just create a custom area for it if you want.
There are tons of tutorials on how to add jquery files in Genesis. You’ll see how to do it by searching for – “how to add jquery scripts in genesis” …..whatever works for one child theme will work for another since Genesis is a framework. So whatever the solution is, it will work for this theme as well.
I noticed you’ve made a lot of posts here recently, so assuming your new to Genesis, I’d recommend checking out the tutorials, code snippets and other resources on StudioPress located here – http://www.studiopress.com/resources and here – http://my.studiopress.com/snippets/ and that should handle most of the basics.
We also have some tutorials specifically for Epik located on the main forum page (stickied at the top) – https://appfinite.com/forum/epik-theme-support/ and a couple more at the top of the menu above – https://appfinite.com/tutorials/ ….this in addition to Googling everything is what helped me get up and running with Genesis. Theres a lot of tutorials out there for Genesis on how to do just about anything.
Hope that helps
