Overview

Group 1 Automotive, Inc., is seeking an experienced Senior Internal Auditor to join our Internal Audit team.

The Senior Internal Auditor is responsible for leading operational audits, advisory engagements, investigations, analytics-driven projects, and SOX compliance activities across the organization. Approximately 75% of the role is focused on operational audits, advisory engagements, investigations, and analytics-driven projects, with approximately 25% focused on traditional SOX control testing.

This position reports to an Internal Audit Manager, who provides engagement objectives, coaching, and quality oversight. The Senior Internal Auditor leads assigned engagements from planning and scoping through fieldwork, findings development, and reporting while providing coaching and workpaper review for staff auditors. Within each engagement, this role operates with a high degree of independence, manages multiple concurrent engagements, and partners with stakeholders across dealership operations and corporate functions to identify risk, improve processes, and develop practical recommendations that support business performance.

The ideal candidate is a self-directed and analytical audit professional who is comfortable operating in a fast-paced environment, managing ambiguity, and designing an audit approach based on the business objective rather than relying solely on predefined audit programs. Success in this role is measured by the ability to deliver actionable insights, reduce risk, strengthen controls, and drive meaningful process improvement. In return, it is an environment where strong auditors grow quickly: every engagement stretches a different skill, decisions carry real weight, and no two quarters look the same.

What This Role Offers You

• Real variety: Operational audits, advisory work, fraud investigations, and analytics projects across dealership operations, F&I, compliance, and corporate functions.
• Real ownership: You are given the question the business needs answered and the trust to design the approach with the Audit Manager. Your judgment is the tool we hired, not just your ability to execute a program.
• Modern tooling: A function already built on Qlik-based continuous monitoring, Alteryx, and Power BI, with AI embedded in daily audit work through OpenAI, Anthropic, and Microsoft Copilot tools, all managed on the Optro (AuditBoard) platform. You will sharpen skills here that most audit shops are still talking about adopting.
• Visibility: Your work reaches senior leadership, and strong work gets seen. This is a function with a track record of developing auditors into leaders.
