Can I submit resumes for two different positions in the same company ~

I don't recommend it. First of all, there are specializations, not generalists. Does it mean that you are qualified for two positions or that your skills in each position are only superficial?

Secondly, the company wants to recruit people with clear career plans. If you hand over both positions, the company will suspect that you have not made clear your position and direction, and it may be easier to resign or jump ship in the future.
