It sounds like if the single member company invoices the foreign company and then pays you as an employee, with all the payroll deductions, that's fine?

That seems reasonable, the only thing is that you have to compare the foreign company invoice rate as a gross payment to salaries offered by domestic companies which are generally quoted as net payments? As I understand it, European salaries are usually quoted fully net --- you get exactly that amount, in contrast to US salaries which are mostly gross, there are a lot of deductions that start from the quoted amount, but some that are employer side and not usually quoted.

european salaries are usually quoted "semi-gross" (or semi-net, according to your optimism). there is an arbitrary distinction between employer contributions and employee contributions, the figure you will be given is after the former, before the latter. and always before income tax of course (because that isn't solely based on your salary)
