It actually shocks me how many senior marketers have no idea how to do this stuff, but then again that is my marketplace advantage.

A lot of senior marketers come from traditional marketing/advertising backgrounds. Where they work with marketing channels that operate on imprecise exposure figures and ballpark ROI calculations. That's what they expect, so when moving into a medium like online advertising they're perfectly fine operating in the same mental framework.

And to be fair, software engineers also tend to suck at that type of marketing plumbing. Did engineering put your conversion snippet directly within an onclick event on the submit button? Then they chose a poor implementation method with a lot of gotchas that could compromise your reporting. You could be over counting by including clicks on submissions that never go through due to validation handling. Or you could be under counting conversions because they didn't properly intercept the submit event and there's a pretty little race condition between the page submitting and your conversion code executing. Or a half dozen other potential pitfalls that need accounted for when using the onclick or onsubmit event.

Marketing Engineering is definitely a good niche to be working in.

For sure. Oddly enough, a lot of people in the traditional/advertising backgrounds do get how to use the mediums effectively, or even how to measure and optimize within them, but when it comes to the technical aspects of setting them up, they are clueless, and don't grok the minutiae.

I wouldn't call myself a Marketing Engineer by any means. I am learning how to be a better coder, but, despite the buzzwordiness of the title, I feel like Marketing Technologist is a better descriptor (for me at least).
