From the announcement:
If you are serious about a career in Bitcoin and Lightning FOSS, we strongly encourage you to apply. We welcome all background and technical experiences, but participants will be expected to work in C++, Golang, or Rust regardless of prior experience. (If you don't know any of these languages yet, YOU SHOULD STILL APPLY. We'll give you the resources to level up!)
Hmm. Maybe that can be clearer. Sending up an edit.
