I was in simmilar situation, even though not as frustrating. Started at a company as a test-automation engineer, but the QA team I was part of was dissolved soon after, and we were redistributed do various development teams. So I changed to be backend-developer but after three months in that role, I didn't feel like I am really contributing. One of the things was, that didn't really feel that I had that much impact on things we were doing in the team, and I learned that the only part of the application I finally started to comprehend a bit will be handed over to a separate team. Secondly, I was only remotee out of 8 people, rest of them in a single office. So I changed to the team on the other side of the hand-over. It is mostly remote (3/5 people in different offices), and I do participate much more.
