Earlier quoted context omitted.
$200k is increasingly a mid-career engineering salary in many parts of the US. Some quick examples taken from companies reported on levels.fyi, where pay around $200k was reported for people working outside the most expensive US cities plus Austin: - Lowe's (Charlotte): https://www.levels.fyi/company/Lowe-s/salaries/Software-Engi... - Equifax (Atlanta): https://www.levels.fyi/company/Equifax/salaries/Software-Eng...…
That ExxonMobile link has 3 of 20 salaries being an amount above $122k and only 1 at $200k. So, even in your cherry-picked examples one of the companies only has a single person making this "mid-career salary".
1 - levels.fyi will not have a record of all the folks working at a given company.
2 - Somebody is indeed the highest-paid engineer at every firm, so that data point is relevant. (It could be you!)
3 - Fine, swap out ExxonMobil for Chevron in Houston and then realize they hire from the same talent pool and likely are in the same total comp range: https://www.levels.fyi/company/Chevron/salaries/Software-Eng...
4 - Take JP Morgan in Houston as a bonus: https://www.levels.fyi/company/JPMorgan-Chase/salaries/Softw...
5 - Yes, some tech people make a lot less than others. It is also true that $200k is still rapidly becoming a mid-career salary in major US cities beyond the expensive coasts. (No, you are not mid-career at age 28.)
