Site Reliability Engineering. It is the role that, among other things, ensures that a service uptime is optimal. It's the closest thing we have nowadays to the system admin role

Seems like that would only be relevant to web development, not software engineering in general.

True, but since the vast majority of software engineering is web engineering and the title is clearly about web, it seems fit to mention that.

IMO, that isn't true, nor is the vast majority of software engineering related to the web.

Every industry has been undergoing digital transformation for decades. There are SREs ensuring service levels for everything, from your electrical meter, to satellite navigation systems. Someone wrote the code that boots your phone and starts your car. Somebody's wireless code is passing through your body as you read this, while an SRE ensures the packet loss isn't too high.

Your point doesn't really change what I said. There are many languages in the world but English is the most common one. Those two facts are true at the same time. This is the same, there are many types of software engineering out there but the most common software engineering job relates to building web applications. If you don't believe me, hit your regular job board and count.

Thank you!
