Of course, the job description should specify education, previous job experience, certifications and technical skills required for the role. You may also include soft skills, like communication and problem solving, as well as personality traits that you envision for a successful hire. While you may be tempted to list out every requirement you envision for your ideal hire, including too many qualifications and skills could dissuade potential candidates.
Properly written job position descriptions are often the only document that totally define what a role is, what skills are required to perform it, and where the role fits in an organization. This makes it simple to identify candidates that are a good fit for the role and also to hold candidates accountable if they are not performing essential duties that are required in the role.
