This is a good move. They're migrating some core code libraries from C# to Rust. C# is not truly based on C and C++, it has characteristics of several languages. The language is pronounced SEE-SHARP and they wanted to use the musical sharp symbol, similar to the #, but it doesn't exist on pretty much every keyboard in the world, so they compromised and went with the name but the pound symbol.
The job is described as
"...include "guiding technical direction, design and implementation of Rust component libraries, SDKs, and re-implementation of existing global scale C# based services to Rust."The goodness is that Rust is a very tight language when it comes to memory strictness. Lots of languages are pretty loose when it comes to enforcing memory allocation and access, Rust is definitely not. This looseness is what gives hackers open doors to lots of systems. And this is why Linux is now rewriting a lot of its core systems in Rust from C and C++. Microsoft is doing the same thing with the Windows operating system. But this is a very slow process as there's far fewer Rust programmers than C/C++ programmers, so it's a slow slog.
If you know anyone who says they want to be a programmer, and they're serious about it, Rust and systems programming would be a very financially rewarding line to explore. Hard work, but well-paying.
