Final answer:
The junior engineer should bring the potential danger to the attention of the company's upper management to prioritize safety.
Step-by-step explanation:
The junior engineer in this scenario has noticed a potential danger in a design that was implemented to save manufacturing time. In this situation, it is important for the engineer to prioritize the safety of the end-users over time-saving measures. Therefore, the engineer should bring the issue to the attention of the company's upper management, specifically the non-technical management.
By raising the concern to higher management, the engineer can ensure that the issue is addressed and appropriate measures are taken to prioritize safety. This is necessary to prevent any harm to the end-users. Reporting the company's violation to regulatory agencies or seeking the opinion of a college professor are also valid options, but bringing it to the attention of the company's upper management should be the engineer's first step.
