You will collaborate closely with Internal Audit colleagues in the U.S. and other global regions, as well as with process and control owners across the organization.

This role offers the opportunity to contribute to a high-performing, collaborative team focused on strengthening internal controls, enhancing risk management, and driving operational excellence across Mattel’s global operations.

What Your Impact Will Be: 

• Perform and document detailed SOX control testing in accordance with Mattel’s Internal Audit methodology and PCAOB standards.
• Assess the design and operating effectiveness of key controls and identify potential control deficiencies.
• Prepare clear, well-supported workpapers and communicate testing results in a concise and professional manner.
• Participate in control walkthroughs and support updates to process narratives and risk/control matrices.
• Collaborate closely with Mattel’s U.S.-based Internal Audit team and business process owners to ensure timely completion of testing and remediation activities.
• Support initiatives related to continuous control monitoring, automated controls testing, and process automation.
• Contribute to continuous improvement initiatives related to testing quality, documentation standards, and process efficiency.
• Maintain up-to-date knowledge of SOX requirements, internal control best practices, and Mattel’s corporate policies.

What We’re Looking For: 

• Bachelor’s degree in Accounting, Finance, Business, or a related field.
• 3–6+ years of progressive experience in internal audit, external audit, or SOX compliance.
• Proven hands-on experience executing SOX testing within a U.S.-listed or multinational organization.
• Strong working knowledge of internal control frameworks (e.g., COSO) and applicable auditing standards.
• Experience performing testing of business process controls, ITGCs, and/or automated controls.
• Exposure to continuous monitoring, automated testing techniques, or data analytics in audit activities.
• Strong analytical mindset with exceptional attention to detail and documentation quality.
• Excellent written and verbal communication skills in English; Mandarin proficiency is a plus due to stakeholder base. 
• Demonstrated ability to collaborate effectively with cross-functional and global stakeholders across time zones.

Preferred Qualifications:

• Professional certification such as CPA, CA, CIA, or equivalent (completed or in progress).
• Experience with a Big Four or large global public accounting firm.
• Familiarity with audit and GRC platforms (e.g., AuditBoard, Workiva, or similar tools).
• Exposure to ITGC testing and advanced analytics tools.
