At my old job I maintained a list of “up for grabs” tickets. They were all very narrowly scoped, so little judgement would be needed. Things like “the text on this button is misspelled” or “add an extra button to the GUI to expose this existing functionality”. These sort of bugs are good “first week” bugs since most of what you learning is setting up the development environment and interacting with engineering systems (bug tracker, code repo, CI/CD).
