Okay, let’s calculate this. So Siteng Yu has a mix of technical and project management skills. Data analysis and finite element analysis are in demand, especially in industries like manufacturing. Matlab and R are popular tools in these fields. Considering his skills and location in Royal Oak, Michigan, I’ll look at average rates for engineers in the US. According to Glassdoor, a senior engineer with similar skills can earn around $80,000 per year. For hourly rates, this translates to around $38–$42 per hour. However, since Siteng is also skilled in project management and has a strong technical background, I’ll estimate his rate to be on the higher side of this range. Let’s say $75 per hour, which is slightly above the average but still reasonable for someone with his expertise and experience.
