Do those different breeds of engineers work in one team or in separate organizational branches? The problem the term 'devops' is addressing, the way I understand it, isn't that of insufficient individual jack-of-tradesness, but that of too much separation between (internal) organisations. It should be perfectly possible to build a "devops" team from deeply specialized experts and turning it into a job description seems quite a stretch to me. But you might actually want some jack-of-trades types nonetheless, because those isolated organizations weren't completely without merit: they are good at solving that problem affectionately called the bus factor. A single ops guy in a devops team is a single point of failure and the mitigation preparation of keeping some of the not-so-ops peers sufficiently in the loop will be much more dependent on organic motivation than the counterpart in a specialist company branch. There, substitutability would be much easier to ensure with formal process.
