I've got the gist of the show based on what you posted in the OP of the IC, but I would like to know more of the tech level of the time we're being sent back from, as well as more about the engineer as a role and team member, similar to your overview of the Historian earlier, when you have a sec. Thank you!
Although much of the information pertaining to the future is purposely obscured, it can be inferred that the technology level of the future is akin to your average sci-fi story; think Blade Runner 2049 but slightly more advanced. Specific examples of future technology that is seen in the original story of the show are items such as medical nanites (A powerful and rare tool, only constructed by doctor teams, but that's a whole different topic), anti-matter storage containers, graphene communication device, and a stasis field generator. In short, the engineer plays the role of replicating advanced technology from the future when a situation calls for such technology. Although the engineer does not hold the knowledge of all the possible technology that may need to be manufactured. The Director will send instructions to the engineer through the deep web for the engineer to process and manufacture. Besides the manufacturing part of the engineer's role, they may also serve in the field as the "person in the chair" when necessary. The engineer often works in tandem with the historian, as the historian possesses the ability to store and recall heavily complex instructions sent from the Director through messengers and the engineer has the technical knowledge to fully understand and execute these instructions.
