Okay, let’s tackle this. So Dave Graden has 27 years of experience as a Senior Principal IC Design Engineer at Medtronic, which is a large medical device company. His experience in designing medical devices is valuable, but the field is also highly competitive. Location is St Paul, Minnesota, which is not a hub for high-paying tech jobs. Considering his experience and skills, I would estimate his hourly rate to be around $125, which is slightly below the national average for IC design engineers in the US. This is because Medtronic is a large company, and while Dave has a long tenure, his role is likely not in a high-paying position. Some IC design engineers with similar experience can earn $200-$300 per hour, but Dave’s role and location put his rate at the lower end of the spectrum.
