Gunner can craft better tiers of weapons, engineer can upgrade systems to better tiers. Apart from that you have to find better guns while playing from missions or random drops

Currently, other types of guns can also be found in the Ship Loadouts.
You can move them wherever you like aboard the ship, and upgrade them with Ship System Upgraders - which you can craft as an Engineer, or find dropped by enemies.

The Upgrader will no longer be locked behind a perk, in the next Update.
There are also numerous crafting improvements to come, as the Fabricator gets a rework now, and it will receive tiers (similar as Modules), which will affect crafting.
