Job Summary

• The CIA’s primary focus is on conducting comprehensive, risk-based audits of Oilserv’s operations, financial processes, strategic initiatives, and information systems, while distinctly assessing the efficacy of the separate Compliance function without directly performing compliance duties.

• Develop, implement, and continuously refine a comprehensive, risk-based annual internal audit plan that aligns with Oilserv's strategic objectives, identified enterprise risks, and the specific needs of the Audit Committee.
