These are all things any engineer should be able to/ does do. The title "lead dev" sounds like marketing.
If you compare with companies with big budget, yes those attitudes are what you find on the average engineer. In the London start-up world where budget is tight and VC's think short term that's normally not the case. It's hard to find solid architectural thinkers with experience who don't call themselves Leads, Architects and so on.
Are these skills and attitudes found in your area as just "engineers"?
