Internal Auditor Cover Letter Examples

Dear Ms. Silva,

I am excited to apply for the Internal Auditor position at Natura &Co. With a strong background in internal audit, risk management, and compliance across Brazilian and multinational environments, I am enthusiastic about the opportunity to support Natura's commitment to sustainable business practices and transparent governance.

In my most recent role as an Internal Audit Senior at a regional manufacturing firm, I led operational and financial audits across 12 business units, identifying control deficiencies and driving remediation plans that reduced quarterly control gaps by 40% within one year. I have hands-on experience with SAP ECC and S/4HANA, ACL and IDEA for data analytics, and a solid working knowledge of IFRS and Brazilian tax compliance. During a process optimization engagement, I introduced continuous audit scripts that increased transaction sampling coverage by 300% and identified recoverable overpayments totalling BRL 1.2 million. Earlier in my career, I completed an internship at PwC Brazil where I supported SOX readiness testing and learned best practices in documentation, testing matrices, and stakeholder communication.

I am particularly drawn to Natura &Co's purpose-driven approach and leadership in sustainable cosmetics. Your emphasis on transparency and responsible sourcing aligns with my professional values: ensuring controls not only protect assets and reputation but also enable ethical, long-term business decisions. I am eager to leverage my audit methodology experience, data-driven testing, and collaborative approach to help strengthen your internal control environment, support regulatory compliance, and provide actionable recommendations that enhance operational efficiency.

I welcome the opportunity to discuss how my experience in audit project management, data analytics, and cross-functional stakeholder engagement can contribute to Natura &Co's continued success. Thank you for considering my application; I look forward to the possibility of contributing to your governance and risk management team.

Sincerely,
Mariana Costa
