This sounds like an entirely in silico research effort. It's also kind of weird, there's apparently no public history of ByteDance or Tiktok doing any kind of work like this. The closet thing is the "ByteDance AI Lab" but that seems to be recommendation-algorithm-focused, nothing about computational chemistry.

It looks like some of their people have recently left for academia, so maybe it's just trying to get people into their AI lab with the necessary skills? Honestly doesn't seem like a very promising role for someone primarily interested in chem/bio applications, though.
