Okay, let’s tackle this. So Jeff Waters has a mix of technical skills like finite element analysis and CFD, as well as business skills like lead generation and product marketing. He also has experience in product development and Salesforce.com. Location is Franklin, MA, which is a smaller town near Boston. While this could impact salary, it doesn’t significantly. Considering his skills and experience, I’d place him in the lower to mid-range of product development salaries. According to Glassdoor, the average salary for a product development manager in the US is around $115,000. However, this role may be more focused on technical skills, so I’d estimate his rate to be around $125 per hour, slightly below the average.
