Pros
Variety to many different processes and equipment found in chemical engineering. A lot of personal ownership, involvement and decision making. A lot of support, opportunities and freedom to develop your skills. Hands on exposure to control systems/DCS, chemical systems, reactive processes, separation processes and more. Perfect for someone early in their career to develop first hand experience in projects, operations and engineering calculations for design/modelling. Get to work with people for a whole range of disciplines and skillsets (operators, engineers, trades) who have decades of experience behind them. They are a wealth of information and you can learn a lot from them.
Cons
Little opportunity for permanent senior process engineering positions and complex design experiences.
