I would say this is pedantic but given I named my character after him...
Stamets isn't actually an engineer! He's from Science. He just has a lab set up in Engineering Test Bay Alpha. We've never actually seen the Chief Engineer on Discovery and have absolutely no idea who they are. There was something incorrectly displayed on screen in Season 1 but the producers and such admitted it was a mistake. That mistake did say that Stamets was Chief Engineer but there were a few other things around it that pointed to it not making sense.
The only Engineering characters we've really seen regularly is Commander Jett Reno and Tilly. Kinda weird that. Everyone else is either command or operations.
I think Jett Reno is supposed to be the chief commander of the USS Discovery, considering she was the chief ___ on the USS Hiawatha. Though the show never explicitly states it, I think it has to do with very old Trek ideas of no enlisted personnel. ie, everyone is an officer who's gone to Starfleet Academy.
She wasn't even the Chief Engineer on the Hiawatha though, she was just said to be an engineer serving onboard, and we know she isn't Chief on Discovery because in Season 2 she says that the Discovery chief engineer sent her to Stamets lab. It's left really vague. The sameway that Culber isn't the CMO as most think he is, that's Dr. Pollard. Discovery doesn't follow the typical thing of focusing on roles onboard but people individually. I love it but it does make things slightly odd when trying to figure out whos who sometimes.
Huh, I guess I just mentally interjected her position as Chief to make sense of her being a Commander then. She's likely the 3rd highest ranking officer on Discovery, and yet she's just a random engineer lol.
Oh that's totally understandable. I did too. I'm not saying this like an "um actually" for the record, just hammering home your own point, but in Season 3 onwards she's third highest ranking. In Season 2 she's 4th highest ranking and still just a fuckin Commander. Pike, Saru, Burnham, Her. Presumably the Chief Engineer also outranks her by position/time onboard and Dr. Pollard is a Commander too so that knocks her down to 6th.... It's fuckin crazy how many high ranking people are on Discovery. Understandable given the importance of the vessel but holy shit.

I think you may have explained why Disco never felt right as a Trek series to me: Not enough engineers!
I think Linus is Engineering but yeah, those are the only characters with any real screentime who are Engineers as far as I'm aware. Although Detmer might be I seriously doubt it.
