I don't have a tidy job title. I've stopped trying to find one.
What I have is twenty-five years of sitting between things: between systems and the people who use them, between technical teams and the humans they build for, between a plan and the reality of executing it on the ground. Between the room where decisions get made and the room where they land.
That gap is where I work. Whatever it looks like in your context.
Sometimes it's a product that needs to make sense to people who weren't in the room when it was designed. Sometimes it's a festival where a hundred moving parts need to arrive at the same moment without anyone noticing the effort. Sometimes it's a dataset that holds answers nobody can read yet. Sometimes it's a team that's technically communicating and somehow not connecting.
The contexts change. The thing I'm doing in each of them is remarkably consistent: finding the point where something should be legible and isn't, and making it legible. Noticing who isn't in the conversation who should be. Asking the question nobody thought to ask because it seemed too obvious or too awkward.
Most people don't notice the gap, because they're standing in it.
