People often use the terms nanoengineering and nanotechnology interchangeably. However, they are slightly different. As the name implies, nanoengineering focuses more on the engineering and product development side of the field. Nanotechnology is more of an umbrella term that covers the entire scientific field. In a nanotechnology role, you may focus entirely on the pure science of the field. In short, nanotechnology is simply the field of study that focuses on the nanoscale, while nanoengineering focuses on the actual engineering. The fields are closely related, and often, those who focus on one have the skills to work in both.
