I do work for an American company but with Canadian branches. I doubled my salary over Canadian tech companies but still only make 50-60% what my American peers make.
Stay away from those ones with Canadian branches, unless you must have the office experience. They always scale pay by location. Corollary, stay away from companies that pay by location when seeking remote work, unless you live in a very expensive location.
Same story for me at my last company, which started up in Canada but then relocated headquarters to the US. Why? Access to funding and industry partners.
I was making great money compared to my local peers. But compared to my American colleagues I was making half.
Curious are you paid less with comparable cost of living of american peers I.e. are you comparing with NY or Bay Area salaries or median American for same skills?
If my CoL is higher living in the Bay Area I would then expect to be compensated for that , and that seems fair .
Even when paid higher the quality of life and net savings people living in high CoL areas have are considerably less than in low CoL so am not sure it is better to have the higher compensation
