Engineering is all about using math, physics, and chemistry to resolve problems. We combine all these learnings to end up with a system that performs a certain job.
Engineering is really about solving difficult problems. Some types of engineering may use advanced science and mathematics such as building new microprocessors with printed wires so small they have quantum effects on the electrons while processing. Other engineers help companies redesign their business processes that run their companies using various statistical analytic methods and process design techniques. While nearly all engineers are trained in math, science, and technology, many only apply the information at a theory level. To explain, I'll talk a little about my path, and realize many engineers have similar paths.
After graduating with my mechanical engineering degree with a focus in materials, I joined a medium size company. While there, I practiced a number of engineering disciplines. Mechanical design for high speed automation equipment. Plastic design for consumer plastic parts formed in injection molds. Engineering with quality statistics practices. Plastic extrusion engineering, and materials friction for high pressure environments.
Another role was designing high speed conveyors to move products around a factory while writing software to control how all things move around those conveyors. Connecting to enterprise systems allowed smart controls to move products to the most optimized location to boost productivity in the whole facility.
Those same problem solving skills lead to developing database and web analytics software to develop early business online analytic systems.
Later applying engineering principles lead to changing how companies work between organizations. Redesigning processes, and developing new methods based in strong analytics are a different form of engineering.
Some people take a far more technical path, and I have met many engineers along the way in IT, Strategy, Leadership, Marketing, and a variety of disciplines. The connecting principle is engineers learn how to solve problems, and the problems they choose to solve follow a wide variety of paths.
Engineering involves finding solutions to problems. There are many areas of engineering such as chemical, mechanical, electrical and civil. With each of these areas, there are different industries/businesss that have problems that need to be fixed. Engineers design towns, buildings, roads, electronic and electrical systems, make chemicals, mine, design boats, planes, and even spaceships. Most all industries use engineers. It a great career. Come joint us.
People have problems. Engineer is the use of Science (not magic or hope or miracle) to apply, build, and attempt to fix the problem. The start might be failure but engineer's job is looking for a way that the solution both make sense and economically viable.
