Actually in terms of finding if job site is useful for me that listing is nice. Quick scroll and I see there are no technologies that I use. No .NET, C#, Entity framework.
A ton of it is security and Data Science related, if you actually look at the jobs. That's one of the reasons python is so popular, it's pretty dominate in those circles.
Fairly standard/boring "we're making a monolithic app in a dynamic language" stuff.
