I work in digital marketing analytics, a lot of clients I work with use salesforce and a big part of my job is setting up for them, linking leads, etc. 

Is there a way for me to leverage my current position to get into something you’re talking about? Wanting to learn a new skill and debating code, so if possible learning Java Script isn’t too much out of the question.

Not hard at all to get into something like a partner firm with knowledge of the field.  I'd start at trailhead.com and start working through some of the sfmc trails and maybe check out some partner firms.  Even if you can snag a job as a project manager, you'd still get access to a sfmc instance to practice in and set a progression towards something like a solutions architect role.
