Worth looking at the Service Inquiry report into the loss of F35 ZM152 where two squadrons were embarked, one adequately resourced with personnel (USMC) the other not (617 Sqn). There is a description of what the squadron engineers have to do, especially "see-off teams"

1.4.152. It was not until the commencement of Op FORTIS that it was discovered just how much carrier operations increased demands on see-off teams. Aircraft were required to be moved around the deck more frequently than was the case on an airfield, placing an additional workforce demand on the Sqn. Also, see-offs required additional tasks such as last-minute refuelling and management of chains,' which required more engineers. The combined effect of these was that a larger engineering workforce was needed when embarked compared to land-based operations. This resulted in personnel being drawn from maintenance work in the hangar. During Op FORTIS twelve 617 Sqn personnel were repatriated to the UK for personal or medical reasons but were not replaced. The panel determined that carrier operations required even more engineers than the DMSpA figure suggested. The limited workforce available to 617 Sqn worked at a commensurately higher, more fatiguing rate and were therefore potentially more prone to errors. The panel concluded that insufficient workforce availability was a contributory factor.
