Okay, let’s tackle this. So Derek has 10+ years of experience in aerospace engineering, which is a specialized field. His skills in systems engineering, project management, and simulation are in demand. He’s also proficient in Spanish, which can be an asset in various industries. Location is Kirkland, Washington, which is in the tech hub of Seattle. Aerospace engineers with his level of experience typically charge higher rates, but not as high as those in top-tier companies or with a Ph.D. Maybe around $125–$200 per hour? But considering his expertise and location, I’ll estimate around $125.
