Doesn't this fall under the already-existing title of Product Manager?<p>The way I look at what a PM does, this is exactly it: knowing the technical aspects enough to figure out what is possible and detail it for engineering to build. It doesn't have to be the same person that specs it and build it.<p>That being said, I'd be very happy to get a job as "growth hacker" for I believe I'm better at thinking that kind of integrations through, than at what is on the "marketing side" of product management.
