Okay, let’s tackle this. So Mark has a strong educational background in engineering, which is a plus. He also has experience in mechanical design, process optimization, and industrial engineering, which are in demand. Skills like Autocad, SAP R/3, and RF testing are also valuable. Location is Dayton, Texas, which is a smaller market. Considering his skills and experience, I’d estimate his hourly rate to be around $125, which is slightly below the national average for engineers in the US. This is because Dayton is a smaller market, and rates can be lower compared to larger cities like Houston or Dallas.
