That seems like a lot of work to be putting on one person's shoulders - flying the ship and also coordinating the offensive drones, while simultaneously serving as a human switchboard between the ship and its manned parasite craft? That is enough work for at least two people, I'd think - Navigation alone is going to be complex enough with a ship like this to be its own officer slot. Radar/sensors should be part of Tactical's responsibility, since they'll also be managing the shipboard weapons and whatever point defense it carries. If our technology base is roughly as it was in Ark Royal, the 'comms officer' isn't anything an automated computer program can't handle if it just involves relaying messages between mothership and parasites or internal messages. Drone operation should probably be a dedicated slot of its own as well - probably a subordinate officer under the Tactical department, or even a team of them depending on how autonomous-capable you want the AI systems to be.
So, to rework my proposal of the duty roster, which you don't have to take but I obviously think makes a lot of sense:
Captain - Oh Captain, My Captain
Executive Officer (XO) - 2nd in command
Navigation Officer - steers the ship
Tactical Officer - manages tactical stuff; weapons, defenses, sensors+radar
Other Key Personnel
CaptainMajor of Marines (because there is only ever one Captain onboard a military vessel, thus a temporary courtesy promotion)
Chief Doctor, keeps the crew healthy
Chief Engineer, keeps the ship healthy
Media Representative/PR Specialist (?)
Assorted Scientists and Technical Experts - geologists, biologists, physicists, xenobiologists, etc.
Medical Personnel -
Scientific Personnel -
Shuttle Pilot(s) -
Drone Operator(s) -
