You said you are 'in the EU', as in currently living in the US for said job?
Are you considered an independent contractor? Or an actual employee of the company?
As a US citizen... I would just advise EU citizens to 'in general' avoid working for US companies, we have bad employment policies, and our companies think they can just do the same things in other countries. Obviously everyone should choose for themselves; if you think the extra income is worth it, that is your call, but our work culture is awful.
At the very least, if you do decide to work for a US company... keep it remote. Cost of living in the US is really high, work culture is awful, it's dangerous, and healthcare costs are crazy. Unless your household is making at least $150k USD/year, you'll be considered poor to middle-class.
