Engineer

An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical, societal and commercial problems. Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word  engineer  is derived from the Latin words  ingeniare  ("to contrive, devise") and  ingenium  ("cleverness").

The work of engineers forms the link between scientific discoveries and their subsequent applications to society's needs and quality of life.

Most engineers specialize in one or more engineering disciplines. One discipline is as a Fleet Engineer. As such, the engineer is responsible for one or more of the base's or ship's systems. This includes not only maintenance and repair, but seeking to improve them in some manner. Because of this engineers are required to maintain and improve their skills and Fleet certifications.
