The role of chief engineer, an engineering position, was occupied by Del Meeko on the Imperial Star Destroyer known as the Implacable. Following Meeko's transfer to Inferno Squad, Naylyn Bashan was slated to succeed him as the chief engineer on the starship. During the First Order and Resistance conflict, also known as the war, Neeku Vozo held the chief engineer post on the Colossus, a circumstance that led the Warbird gang, a pirate group, to view Vozo as an asset for their planned mutiny utilizing his engineering skills.
