Sr. Internal Auditor

GHD•Phoenix, AZ

About The Position

GHD is seeking a Senior Internal Auditor to join its Global Internal Audit team. The role may be based at any GHD office in the Mountain or Pacific time zone in the United States or Canada. The Senior Internal Auditor leads process and operational audit engagements from planning and scoping through fieldwork, reporting, and close-out, working with stakeholders across functions and geographies to evaluate business processes, risks, and controls using traditional audit techniques and data analytics. The position calls for a proactive, data-literate auditor who works independently, navigates complex information, and communicates clear, practical, evidence-based insights. The role also contributes to quarterly Internal Audit reporting for senior leadership and the Board Audit Committee, improves audit methods and analytics capabilities, and supports special projects, including confidential integrity- and fraud-related investigations. Moderate domestic and international travel may be required. Success in the role includes taking ownership of engagements, identifying root causes and broader control implications, producing concise and evidence-supported audit deliverables, using data and technology to improve audit coverage and insight, maintaining effective stakeholder relationships while preserving independence and professional skepticism, and exercising sound judgment and discretion when handling sensitive information.
