My formal title is Senior Automation Engineer. In the broadest sense, I bring the knowledge and problem solving ability of an engineer
Day to day, an engineer in my position spends the vast majority of his time communicating. This can be as simple as a conversation with the field personnel talking through possible ways to perform the task to something as complicated as a formal meeting with minutes and presentations and the like. If there is an issue, the Project Automation Engineer is the primary conduit through which it gets communicated to the designer and how the solution gets back to the guys performing the work. The engineer needs to have a solid grasp of the problem to properly communicate it up the chain and an understanding of the solution provided, both to determine if it solves the problem and to communicate it to the people doing the work.
