Well, the Drive technician works on drive systems under the direction of the engineer.
But the title is a triple entendre.
There's the Drives of the ship, but also the human drive aka seduction assignments, and the occasional bit of ultraviolence, which is represented by the drive to survive.
Between the three, your full skillset is covered.
Many of these titles are only tangentially related to their actual function. Because 'Mechanic, Seductress, and Assassin' looks suspicious on a resume. ;-)
