“At the helm” is not entirely incorrect in that it‘s a colloquial term generally used to refer to being in charge.
Other acceptable terms are:
At the controls (there’s nothing sexist nor sexually-related nor gender-related about it), at the throttle, behind the joystick, in the captain’s seat, in the captain’s chair, in the cockpit, at the con, on point, taking the point, headin’ up the posse, headin’ up the cattle drive, riding first chair, in the saddle, leading the charge, calling the shots, quarterbacking, etc.
