An example of a technical writer is someone who writes computer software documentation.
technical writer - Computer Definition
The person responsible for writing hardware and software documentation, online help, technical definitions and product descriptions. Quite often, the technical writer is given the task of documenting an application at the last minute, allowing very little time for a thorough understanding of all the options, let alone time for others to read and edit the material before it is published. A Necessary Evil Although technical writing is a skill that takes years to learn, and while some companies do appreciate it, most do not. Technical writers are often given less attention than other professionals in the field. As a result, almost all the documentation we read could be better, and much of it is downright indecipherable. Is it any wonder that even technical people avoid reading manuals at all costs (see RTFM)?
