I also work an office job. Though because we're expanding and our new office isn't ready yet, it's been more of a work from home job recently. XD
But my office job is pretty specific. I work for an embroidery/printed apparel company so I have to fix submitted designs before they go to production. Basically, some people try to submit photos or very detailed images for embroidery and I get to break their hearts (not really, okay). lol So mainly I fix images in Photoshop. Sometimes, I create designs from scratch. Sometimes, I help QC production files. And rarely I get to even help out on the production floor! Don't know if I'll be able to help out much this holiday season though because of the work from home thing.
My characters from True Power are mostly too young to have jobs or too old for their job to be relevant to the story anymore. LOL
In my comic Celestial Chronicle Shion, I guess "ship captain" is pretty cliche for a sci-fi story. Though an interesting twist is that they're basically forced into becoming the captain of their ships due to an extremely rare, "special ability" that they had the fortune of gaining. Then there's the typical bridge crew and fighter pilots.
