Depending on the place, it can mean different things. I've seen it also mean "team member" or used for senior engineers whose roles (navigating across different teams on short/mid-term important/investigation/transformation projects not necessarily visible on the official R&D roadmap) makes it difficult to attach them to a particular team/specific role. The people and places that handled well this level of fuzziness do so _thanks to_ a good amount of trust, care and shared vision.
