Internal Auditor Job Description & Profile

Internal Auditor Job Description and Profile

Who Are Internal Auditors?

The job of internal auditors, entrusted with examining the company’s financial statements, operations, and business processes, is sometimes viewed as a source of discontent in the corporate world. However, in reality, they are the Batman of the boardroom, rising to save the day when things go wrong and defending the organisation against fraud, corruption, and other nefarious activities. The Institute of Internal Auditors (IIA) defines internal auditing as follows:

“Internal auditing is an independent, objective assurance and consulting activity designed to add value and improve an organisation’s operations. It helps an organisation accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes”.

What Does an Internal Auditor Do?

Internal Auditors are considered the third line of defence for the organisation. They protect businesses from internal and external risks by raising red flags in appropriate forums and taking adequate mitigating actions to keep these risks within an acceptable level. Internal Auditors report to the Board Audit Committee, and they use a systematic process which includes the following steps:

Audit Planning

Includes issuing the engagement letter, preparing a Risk and control Matrix (RCM) and audit programme, a list of information and scheduling the meetings.


Fieldwork is completing the audit programme by gathering, reviewing, evaluating the information, and documenting the conclusions.


Involves issuing an audit findings memorandum, conducting an audit closing meeting and issuing the draft and final audit reports.


Follow-up is a process of checking with the auditee the status of the agreed action plan—the follow-up of each audit’s timing decided upon the audit’s closing.

Additionally, the Internal Auditor will also complete the Audit Committee’s document process by presenting periodic reports on audit findings and the progress of the audit plan.

How Has the Internal Auditor Role Evolved?

The role of the Internal Auditor has evolved over the years from a purely compliance-driven function to that of a strategic business partner that helps organisations achieve their goals and objectives.

The Institute of Internal Auditors (IIA) is a global body that governs the internal audit profession. In 1941, in North America, the IIA was founded. And it now has a presence with 200 chapters in more than 170 countries.

Historically, Internal Auditors were watchdogs, responsible for ensuring that the organisation complied with the relevant laws, regulations, and internal policies. In the 1990s, with the emergence of new rules and technologies, there was a shift in the Internal Auditor’s job role to that of a more proactive approach. The IIA introduced the International Standards for the Professional Practice of Internal Auditing (Standards), which guide the conduct of internal audits and the management of internal audit functions. Internal Auditors, after that, began to focus more on risk management, identifying potential risks to the organisation and developing strategies to mitigate those risks.

In the early 2000s, Internal Auditors began to work closely with senior management to identify key business risks and provide recommendations for managing those risks. They also focused on value-added activities, such as process improvement and operational efficiency.

Today, the Internal Auditor role has evolved even further. Internal Auditors are now seen as trusted advisors to the organisation, providing insights and recommendations to senior management on a wide range of strategic, operational, and financial issues. They are also involved in various activities, such as corporate governance, ethics, and sustainability.

Internal Auditor Job Description

An organisation can modify the job description of an internal auditor to meet their needs and the position’s specifications. Here is an example of an Internal Auditor’s job description:

What Are the Elements of Modern Internal Audit Methodology?

Modern internal audit methodology has evolved to keep pace with the changing business environment and the increasing complexity of organisations. It involves a risk-based approach which focuses on identifying and assessing risks to the organisation and providing assurance of effective risk management. Consequently, Auditors develop their annual internal audit plan based on the level of risk to the organisation rather than conducting audits on a random or periodic basis.

Auditors are adopting agile methodology, which emphasises collaboration, flexibility, and continuous improvement; this helps them to adapt to changing circumstances and deliver value-added insights and recommendations to the organisation. Additionally, Auditors are working closely with other assurance providers, such as compliance, IT security, and risk management, to provide integrated assurance to the organisation.

Auditors also use data analytics to spot anomalies, trends, and patterns in large volumes of data, which helps to identify potential risks and areas for improvement.

What Is the Future of the Internal Auditor Role?

The scope of the internal audit role has significantly evolved over the past several decades and will continue to change with new challenges and opportunities. In addition to their traditional role, Auditors increasingly provide assurance and advisory services in other areas, such as cybersecurity, sustainability, and culture. Overall, the future for the internal audit job role looks promising, but it will require them to adapt and develop new skills to meet changing priorities for organisations.
