Process Engineering provides the chemical or biochemical processes and equipment that are used to turn raw materials into an end product and is an essential part of the manufacturing industry. Process Engineers create, set specifications, develop, implement and monitor this equipment or these processes as part of the manufacturing system. Within pharmaceutical and medical device manufacturing, the processes involved can be chemical or biochemical. Process Engineering is at work during all stages of the manufacturing process. These engineers can be designing innovative processes and equipment for a new facility or they can be involved in the modification and optimization of equipment and processes that are already in place. As a result, Process Engineers work with people all across the manufacturing system including R&D, production staff, management and even customers.
