Such a nice way to start off the week, colorful phrases akin to "enthrall me" getting wacky connections to careers. My favorite was ROCK MY WORLD, perfectly tied to a seismologist. (Also very nice would have been a diamond seller, using the slangy meaning of "rock" in an engagement ring.) Love the consistency; each of the four themers having a (verb) MY (noun) structure.
Typically the "pinwheel" arrangement doesn't allow for a lot of great long fill, as it's too easy for the theme to get muddied up. After seeing the grid, I girded myself to get theme and not much more, but boy, was I pleasantly surprised. John gives us a clinic in how to wisely use your moderate-length fill. I thought I was lucky to get CAMP OUT, ALL TOLD, and PAIR UP right off the bat, and the goodness kept coming. ZEPHYRS and LIP SYNC anchor the other corner, and STIR FRY puts the exclamation point on the end with its fantastic clue, playing on the "walk" and "wok" homonyms. Newer constructors — heck, all constructors — ought to study how carefully John picked his moderate-length fill, maximizing the sizzle.

I didn't know what REDOUBT was, but I liked learning about it. This is the right way, in my eyes, to introduce a new term to people's vocabulary — 1.) all of the crossings are perfectly fair, none of them even remotely possible to get wrong, and 2.) having it be the only odd duck in the grid. I like learning a thing or two, but like most lazy folks, one is better than two for me on a Monday.
I might have given it the POW! if it hadn't been for a few things. LIGHT MY FIRE clued to an arsonist … that's not really a career, is it? (Don't tell any of the kids I work with if it is.) I like John's pyrotechnician, which could have also been candlemaker. LED designer? Cinematographer? I understand the difficulty of not being able to use "light" in the clue — lighting expert, light designer — but this one inconsistency sticks out in a big way to me.
It would have been nice to see a couple of longer bits of fill, too. (If the square between BUILT and FAB had been taken out, for example.) This theme is so overt that it'd be tough to confuse long fill and themers. That may have not allowed for all the fantastic mid-length fill, but given how well John executed on it at 78 words, I bet he'd do just fine at 76 words too.
Very fun solve, a pleasure to write about.
