Writer for American English texts

We're looking for a writer who has experience with technical writing, copywriting, and/or creative writing.
Must be able to write in American English, using grammar, spelling, and punctuation that would be acceptable in the U.S.
Please apply with a letter detailing your writing experience. Links to your writing portfolio are also welcome but not required. Creativity is always appreciated and will make you stand out from a sea of applicants who all send identical sounding applications. And to help us filter out and delete spam, please put writer and your name in the subject line.
Applicants who can work during U.S. business hours will be given preference, so please indicate your intended working hours in your application.
You should be willing to get on a call shortly. We're hiring immediately.
