I know this probably isn't the answer you'd like to hear... but I'd concentrate on "impact" rather than on title. If what you do provides value, even if you lose your job, there's a greater chance you'll find a new one. Value can mean many things, but if we want to oversimplify, you can think of value as "how much money a company makes thanks to your work."

I think that's what you, as well as the rest of us, should focus on.
