As part of our team, our goal is to provide a training opportunity to engage in the roles and responsibilities of an infrastructure focused process mechanical engineer. You will also collaborate with our CAD designers to communicate how process mechanical requirements get translated into construction drawings. This role will help you build a solid foundation in the fundamentals of Process Mechanical Engineering and show how mechanical design integrates with and impacts other disciplines.
