An engineer of the Imperial forces was involved with the Death Star initiative at the Maw installation as it neared completion, as Darth Vader had just Force-choked Bevel Lemelisk, leading to the latter receiving bacta therapy.
This engineer was a character controlled by a player within the Death Star Designer online game. Grand Moff Tarkin himself welcomes the engineer and reveals that the principal engineer, Bevel Lemelisk, experienced a "regrettable, almost deadly choking incident," which resulted in the player's character being appointed as the project leader until Lemelisk recovers.
