Internal Auditor: Facts, Skills, and Next Paths

Internal auditors review financial records, test internal controls, and assess compliance with laws, regulations, and company policies. They conduct audits across departments such as finance, procurement, and human resources, analyzing data to identify risks and recommend improvements. Day-to-day work includes documenting findings, preparing reports, and collaborating with management to address control weaknesses.

Core responsibilities include leading or assisting on audit engagements from planning through reporting, as described in postings from Serco USA where auditors act as on-the-ground leaders for federal contract audits, and at KPMG where senior associates lead internal audit engagements. The role sits within an internal audit team that reports to senior management or an audit committee, providing independent assurance on operational effectiveness. For example, at Kforce Inc., a senior internal auditor helps develop project scope for clients in real estate and financial services, while the U.S. Department of Defense hires team leads to oversee audit work.
