I know that they are synonyms. But is there any slight difference between them?

They are different terms:
Not giving sufficient attention or thought to avoiding harm or errors.
A person not showing a proper sense of responsibility.
They are very different, cannot be used interchangeably at all.
Careless — Do not care.
Irresponsible — It is your responsibility to "care" but you did not.
