An engineer uses scientific and mathematical knowledge to solve problems.  In general, as an engineer, you would:

• Determine how a system should work and how a change in conditions, operations, and the environment will affect outcomes, similar to what a weather forecaster does.
• Arrange things in a certain order or pattern according to a certain set of rules.
• Imagine how something will look after it is moved around or when its parts are rearranged.
• Predict when something is likely to go wrong.
• Use logic to determine errors and decide what to do about them.
• Seek out new ideas and approaches.

You'll also need to:

• Be a good listener
• Be able to communicate information so others will understand.
• Plan and prioritize your work.
• Keep up to date with technology.
• Strive to make things work more efficiently and effectively.
