Okay, let’s tackle this. So William Wang has 14 years of experience as a Product Engineer, which is a solid amount of time to develop expertise. The industry he’s in, telecommunications, is known for having a range of salary scales. In China, where he’s based, the average salary for a Product Engineer can vary widely depending on the company, location, and specific role. However, based on general benchmarks, a Product Engineer with his experience and education could be estimated to charge around $75-$125 per hour. Considering his location and experience, I’ll estimate around $75 per hour, which is on the lower end of the range, but still a reasonable estimate.
