(Disclosure: I work for Triplebyte and helped publish our salary dataset recently.)
$150K is below the median base salary offer we see for senior software engineers. See https://triplebyte.com/software-engineer-salary -- with a few notes:
* This is base salary only. Total compensation is significantly higher once you include factors like equity compensation, bonuses, benefits.
* This does vary a lot with stage of company. Earlier-stage startups use more equity and less salary. We work with companies from pre-series A to public megacorp.
* This is for senior engineers. Less experienced engineers do typically earn less.
* We're fairly selective in the engineers we work with, but it's based on the abilities you demonstrate in our multiple-choice quiz and technical interview, rather than your credentials.
