How to become one
No particular education or qualification is required to start. Many people have studied chemistry or mechanical subjects at technical high school, university or similar. The work varies a lot depending on the stage and type of medicine, so after joining there is in-house training in the knowledge and skills each task needs. Gaining related national qualifications such as hazardous materials handler or poisonous and deleterious substances manager widens the work you can do in the factory. Production is highly mechanised, so basic knowledge of electrical and mechanical subjects is needed. Because medicines are special products, specialist knowledge of chemistry and biology, and also of microbiology, fermentation and physics, is needed. The work affects people's health, so you must follow production and quality control rules with great care.
