I recall quite a few posts about the shipping crisis last year and Flexport posting lots of "here is the real reason why LA's port is jammed". I recall the story about the CEO buying the longshoremen breakfast and getting the "inside skinny" on how container traffic works.

And the response, even on HN was was "whoa, these guys are so cool" and "more companies need CEOs like this who are innovative and hustlers like this guy". It was their entire schtick.

This isn't to say they didn't have interesting things to share, but the PR/Code-bro-speak was turned up to 11 and it was a huge turn off.

So maybe not that surprised they use words like "grit" in their job postings. I personally would reserve such a word for things like fighting in a war or doing a solo trek to the South Pole, but hey, apparently Flexport thinks their job is at the same level?
