Thanks for this advice. In either case I'd be paid enough to be comfortable, but I wonder if passing up the pay bump will put me further behind in my career. I'd like to get to the pay level in job #2, and I fear working at #1 will slow down my progress toward that salary.
On the other hand, I think job #1 will have more interesting challenges (building out a new product from scratch), but I don't like the space or business as much (social media).
Nothing about this choice seems easy or straightforward to me and I'm so worried about making the wrong decision and regretting this.
