Engineering is a broad discipline. There seems to be an engineering discipline related to almost everything around us. There are chemical engineering, civil engineering, industrial engineering, electronics engineering, and communications engineering, to name a few. One specialty in engineering that seems to be broad in itself is mechanical engineering. To put it simply, it is engineering related to machines - anything with mechanical components. In a project, it is important that mechanical engineers are well-trained. One person responsible for the mechanical engineers in a given project is the principal mechanical engineer.

Principal mechanical engineers oversee the whole project. They also manage the personnel involved in the project. They ensure that principles of mechanical engineering are properly applied in everything done on the site. In addition, they also ensure that plans are clearly laid out and followed by the people. As an added task, they also ensure that rules and regulations set by the company, the partners, and even the government are followed.

If you have an interest in working on mechanical projects, such as designing, building, and testing, this is a job for you. Of course, you need to have leadership skills as well.

What general advice would you give to a principal mechanical engineer?
