First and foremost, I love the question! I have not read the bobiverse yet, but it have put it on my reading list.

A few comparable series and books (disclamer: have not read Bobiverse yet - take with a grain of salt):

• The Hitchhiker's Guide to the Galaxy series. Light hearted Science Fiction by Douglas Adams.
• Anything by Tom Holt. Dry English humor that combines SF and mythology with normal everyday corporate life.
• Charles Stross's Atrocity Archives. I only read the first of 14-ish parts, but it is humorous, fast-paced and very wry.
• Space Opera by Catherine Valente. Think Hitchhiker's Guide meets the Eurovision Song Contest.
• Legends and Lattes was already mentioned. Its prequel, Bookstores and Bonedust is equally fun. The author is Travis Baldree.

I recommend "Old man's war" and "the forever war". Second the murder bot diaries, already mentioned.

"The Martian" was a great movie, but the book was even better. If anything the protagonist is even more snarky. "Project hail Mary" is by the same author.

Dungeon Crawler Carl is a great series that is not space/sci-fi but a fun LitRPG.

You mentioned you like the light-heartedness of the bobiverse series, not necessarily the hard science aspect. There are a lot of "Slice of Life" fantasy out there. I'm not aware of too much slice of life sci-fi.

Take a peek at:

• Beware of Chicken
• Legends and Lattes

If those are things you are interested in, let me know and I can recommend more.

The Divine Dungeon series scratched much of the same itch for me!
