Fabfitfun is a company I have interviewed with, they say I’m a cultural fit and they love my experience. They plan in doubling in size this year and have asked me to be patient, which I’m not. I think there is opportunity to pitch a position to them, that they should incorporate into their company, and hire me for (obviously) but I’m unsure as to how to start as I don’t totally know their gaps and needs. This would be for buying or merchandising. Any suggestions? Thank you in advance!
I don't think you are in any position to negotiate creating new roles in the company. You don't know the details of the organization and the relevant stakeholders, and they didn't hire you as an organizational consultant. To suggests smth like that is unrealistic at the stage you are in and might put you in a bad light for thinking that. Get into the company first, build rapport with people, then suggest ideas.
Ask to speak with more people on the team whose experience intersects with the role you want to create.
