• Build strong stakeholder relationships while maintaining auditor independence and the confidence to challenge constructively.
• Support external audits, certification activities, and continuous improvement of the IMS, including development of the Annual Audit Programme.

Qualifications:

• Good understanding of integrated management systems and standards including ISO 9001, ISO 14001, ISO 45001 and ISO 19443.
