The pattern is:
So here:
- 公司 = company
- 正在 = in the middle of / currently
- 招聘 = recruit / hire
So the sentence literally works like:
The company + is currently + recruiting.
正在 marks an action that is in progress right now.
It is similar to English is/are doing or currently doing.
So:
- 公司招聘 = The company recruits / is recruiting / hires, depending on context
- 公司正在招聘 = The company is recruiting right now
Adding 正在 makes the ongoing nature of the action clearer.
