A part-time technical writer creates content that communicates technical information, often to an audience that is not necessarily familiar with the technical terms. As a part-time employee or contractor, you perform your work duties for less than 40 hours per week. Your responsibilities as a technical writer depend on the subjects about which you write. You can write instructional manuals or explain directions for using or assembling products. Some specialized writers prepare patent applications, grants, or medical documents, while others write product descriptions or simplify technical information for non-experts. In addition to writing content, you may edit or update existing technical writing.
