Looking for sci-fi where the protagonist is just... doing their job
I'm in the mood for science fiction where the main character isn't the chosen one, the captain, the genius who invents everything, or the person who accidentally becomes the most important human in history.
I'd love stories where the protagonist is an engineer, maintenance tech, mechanic, cargo handler, station operator, repair specialist, or someone in a similar role who's just trying to do their actual job. The stakes can still be huge, but I'd like to see them from the perspective of someone who normally wouldn't be the focus of the story.
Bonus points if the technical work actually matters and isn't just background flavour. I really enjoy competent characters solving practical problems without suddenly turning into action heroes.
I've already read Project Hail Mary, The Martian, and most of Becky Chambers' work.
Any recommendations?
