Yeah, I was "flight software" on a control shift for a Dragon space capsule when I was 26, and the "mission director" was probably a year or two younger than me. Other shifts had older directors though.

Flight software is a fun role because they're the first person anyone asks when something goes wrong. "What's causing that sensor to glitch out, is it a bug?" "Uh no, probably not. Hey I'm just a software engineer, but is it possible the pyrowhatzit is actually melting right now?" "Oh crap"
