I want you to act as a recruiter for an [INDUSTRY] @ company. I need you to write 3 friendly job descriptions for seasoned technicians (at levels 1, 2 & 3), including all of the responsibilities and requirements they’ll need for each role. We are [CERTIFICATIONS] certified, which would be a nice-to-have but we also offer certification once hired.

Replace all [info] with information relevant to your business.
