In a team

Elle, 

yes,  ‘ dans une équipe ‘  is standard in French. The expression “ faire partie de .. “ is also commonly used. 

There seem to be regional differences in the English also - ‘ in a/the team ‘ is probably still most commonly used in my part of the world ‘, although ‘ on a/the team ‘ is also in use.
