It is well-established that engineering is a big part of the game, by unlocking the engineers, engineering your modules and ships, it completely changes the game (for the better!). This list of information and requirements for all of the engineers will help you with this task.
This will be a hard work. But again - absolutely worth it!
The list is roughly ordered by the ones you unlock first. Also pay extra attention to the last 4 as they are in Colonia which is about 22,000LY away from the bubble. Before doing the trip there it is suggested to plan ahead all that is needed to unlock them. Maybe even catching a ride with a fleet carrier, there are plenty going back and forth.
