"Sophie and Anne want to be computer scientists."

Translation: Sophie et Anne veulent être informaticiennes.

[ChrisBird6]

Why is there no definer, des or les, in front of informaticiennes here?

[dorianbtdp]

In french we don't put definers in front of professions

[RQZ.Sash]

Why is informaticiens not correct? I think if there are multiple people it should be a masculine unless all the people are female. Or are Sophie and Anne both considered female name?
