Install, fix, and tweak parts of various products.
A modern engine is made up of a variety of small parts, all moving together in a very organized, synchronized way. If one piece is tightened just a bit too much, or one belt is left just a bit too loose, the engine will be slightly less efficient. As an Engine Calibration Engineer, you spend the day making sure that never happens.
If you’re working on a new product line as an Engine Calibration Engineer, you meet with the Product Designers and discuss how they’d like the product to work. As an Engine Calibration Engineer, you then get to work on your computer, running simulations. You may toy with the idea of making bolts slightly smaller, for example, or making the fuel lines slightly bigger. Once you’ve found a design you like, you ask the team to make you a prototype, and you run tests on that engine.
If you’re working with an existing engine, you may take it apart then put it back together in slightly different ways. You may work with other Engineers to determine if a different fuel would work better, or if the software that runs the engine needs minor modifications.
You then run simulations on the computer, but also test the engine in the field. If you work for an automotive company, this may mean spending many days driving very, very fast. Your mother may not approve of this aspect of your job.
You keep strict records of each test you run because you need to prove that you’ve tried all configurations, and you’ll want a record of your skill in finding solutions. This will come in handy when it’s time for your annual performance evaluation.
