We might forgive junior software engineers (a.k.a. junior developers) for being ignorant of many things. The field of software engineering is both broad and deep, and it takes many years to come up to speed in all necessary aspects. Indeed, I have seen many engineers with even 10+ years experience having major blind spots and shortfalls in their knowledge. Are the latter “senior engineers”? Many of them bear this title. Outwith my issues about titles, I posit that there are numerous topics, mastery of which is require to fairly assume the title of “senior engineer” (hint: coding skills are but one of some fifteen or twenty such topics).
