It's worth noting in general, for engineering, the "brand name" factor of your university is often a lot less important and/or doesn't correlate that much to league tables. For example, Strathclyde and Heriot-Watt are extremely employable universities for engineering and often "targeted" by the few companies/roles that tend to do that in the sector. However, they aren't "Russell Group" and they sometimes don't do as well in overall rankings, and applicants sometimes seem rather put off by this. In reality though they are extremely strong options to choose, especially if you are planning to stay in engineering after you graduate (rather than e.g. try to parlay your engineering degree into a career in finance or similar); in fact, they are actually better than some of those RG unis that do well in overall rankings, who happen to have weak engineering departments and get held up in the rankings by their other, stronger departments..
The above is just an illustrative example, but the salient point is that with engineering, if that's your planned career, you really need to shed any preconceptions about "prestige" and ranking, because by an large they simply don't apply. As above though, UNISTATS has a lot of helpful statistics and in particular actually contextualise these (e.g. those stats on which sector specifically graduates get employed in), so I would echo the above sentiments about checking that out.
