You’re forward‑thinking. You take initiative and don’t wait to be handed a backlog.
You’re flexible. You’re comfortable with ambiguity and eager to push the technical state of the art.
You own the problem. You can spot a mission gap, frame a solution, and drive it to delivery.
You dive deep. You need to understand how things actually work, and you build prototypes and experiments to prove it.
You live on the bleeding edge. You track upcoming platform features and can’t wait for the next nightly to drop.
You’re a great teacher. You break down complex concepts for any audience and make the ideas click.
You’re mission‑driven. “Operationally relevant” isn’t a buzzword to you, it’s the bar you expect to clear.
