If you have a way with words and enjoy details, research, and problem-solving, especially in the fields of science and technology, a career in technical writing may be for you.
Preparation. A good way to train for such a career is to major in English in college and be involved with writing of all kinds: journalism, creative writing, etc. Search out internships with publishing houses, newspapers, and magazines to get lots of first hand experience. Volunteer at a local STC chapter (see below).
Loner or collaborator. You also have the option of working alone or with a tech writing team, as a freelancer or an employee.

C.V. Be sure that you have an impeccable c.v.; you can't afford to have a single typo when you're applying for a job that demands attention to detail.
Types of jobs. You will have to get familiar with the background of whatever project you work on, be it technology-related, medically-related, or related to science, web design, airplane mechanics, etc. You also need to be familiar with several types of software – whichever the job requires.
