Depends. Are you legally employed by the US company? If yes, I do not know but I suspect you would need a worker visa as there is no specific remote worker visa so B1/B2 makes me suspect this is not the case.
So I will readily presume you are legally employed by a company in your home country (which you might own) or simply self employed and have a contracting relationship or the US company owns the company you work for etc. In this case, my personal experience is that noone gives a damn: if asked at the border you can answer truthfully (and if you are well prepared, also prove) that you are employed by a company in country X. You will have hotel reservations and the plane ticket out of the country. That's enough. Never lie to a border officer and never offer information unasked.
