TN Visa Eligibility for Medical Writer Position

Hi all, I am a Canadian professional seeking job opportunities in the U.S. I work as a Medical Writer, primarily focusing on regulatory writing, including Clinical Study Reports (CSRs), Clinical Protocols, Investigator’s Brochures (IBs), and related documents. I would like to know if my role qualifies for a TN visa under the USMCA (formerly NAFTA). If eligible, under which category would it fall? My educational background is a PhD in Pharmacology. I appreciate any insights or experiences you can share. Thanks in advance!
