Jobs in engineering involve the practical application of science, mathematics and research to almost any conceivable aspect of life. Since the dawn of humankind, engineering has played an important role in developing technology and creating the infrastructure that form the foundation of modern civilisation. Jobs in engineering can cover a wide range of fields, allowing those who pursue these jobs a broad choice for a career focus that fits their interests. Someone interested in ecosystems and human impact on nature might consider a job in environmental engineering, while another fascinated by urban planning and improving quality of life may consider civil engineering. Jobs in engineering may also be an alternative to practising medicine for biology fans, as medical engineering is one of the fastest growing job fields in the 21st century. The job exchange called StepStone is an excellent source to visit for more information on vacancies and job openings in the field of engineering and many others. Becoming an engineer takes time and education, and the reputation of the engineering school can be a big help in securing jobs. During university studies, students will select a focus for their degree in order to specialise for jobs in engineering, such as mechanical, electrical or environmental engineering, amongst others. In the beginning, a new engineer will work under the supervision of a professional engineer and may gain this status after years of experience."
