Describe the purpose of the role and the responsibilities a successful candidate will handle. Separate essential requirements from skills that can be developed after appointment. Include location, schedule, employment type, reporting arrangements, and a proposed compensation range where available. Explain relevant equipment, systems, or specialist experience. Agree how interviews, references, and required checks will be handled. Review candidates against the work requirements, keep information within the authorised hiring team, and tell the recruiter when the role or timetable changes.
