The Internal Audit team plays a critical role in safeguarding the firm's assets, ensuring robust internal controls, and supporting risk management across a high-profile, complex, and highly regulated organisation. We operate in a dynamic environment, providing independent assurance and insight to senior leadership and governance bodies. Our work spans financial, strategic, operational, and compliance audits, and we are instrumental in helping the firm meet its regulatory obligations and strategic objectives.

From an administrative perspective, it sits within the Quality & Risk Management function.

As a Senior Internal Auditor, you will play a pivotal role in driving Forvis Mazars’ strategic priorities by delivering high-impact internal audit assurance and advisory reviews. You will assess the adequacy and effectiveness of controls in place to mitigate key business risks and priorities, evaluate compliance with regulations, and provide insight that supports continuous improvement across the firm. In addition to core audit delivery, you may also contribute to the function's ambition of positioning Internal Audit as a trusted advisor within the business, for example, by attending working groups or offering insight during the development of internal initiatives or change programmes.

This internal facing role will principally involve working with the Head of Internal Audit, Senior Internal Audit Manager and Manager, service lines and different functions across the BST.

This role demands a high level of curiosity, initiative, and critical thinking. You will be expected to go beyond the checklist, proactively identifying key and emerging risks, evaluating controls, and recommending practical, forward-looking solutions. Equally important is your ability to manage relationships professionally throughout the internal audit process: setting clear expectations, maintaining regular communication, and anticipating issues to ensure the delivery of high-quality, timely insights.

You'll be joining the Internal Audit team at an exciting point in our journey. Building on the progress of recent years, we're evolving into a more strategic, insight-driven function—broadening our influence, deepening our advisory role, and strengthening our visibility across the firm. You will also contribute to the development of audit methodologies and play a key role in shaping the Internal Audit function's visibility and influence across the business.

You will report to the Internal Audit Manager. They in turn report to the Senior Internal Audit Manager and the Head of Internal Audit who reports to the Forvis Mazars Audit and Risk Committee, on behalf of the Governance Council.
