About The Role

As S4Capital continues to evolve in a complex international market, we are seeking an experienced Internal Audit and Controls Manager across audit, risk, and financial control frameworks. This is a key, highly visible management role within the function, offering the opportunity to act as a trusted advisor, shape our global governance environment, and directly influence operational excellence. You will play a pivotal role in shaping and strengthening governance, risk management, internal audit delivery, and the financial control framework.

Responsibilities

• Methodology & Strategic Planning: In conjunction with the Head of Internal Audit and Controls, design and implement an internal audit and controls methodology aligned with Institute of Internal Auditors (IIA) Standards, and contribute to the development of the annual internal audit and controls team plan.
• Audit & Review Delivery: Manage the end-to-end delivery of assigned audits, reviews, and targeted "deep dives" into entities and/or key business processes to time, cost, and quality (from planning through fieldwork to reporting), obtaining key stakeholder buy-in.
• Control Framework & Monitoring: Ensure the group operates a fit-for-purpose financial control framework by designing and delivering an ongoing quality review and controls monitoring programme (acting as a second line of defence).
• Process Design & Documentation: Support business entities in designing and implementing processes and controls across all financial and operational workflows, including developing and reviewing process documentation and Risk and Control Matrices (RCMs).
• Team Supervision & Quality Review: Review the completion and quality of work performed by other team members to ensure controls are appropriately tested, conclusions are robustly supported, and skills/knowledge are effectively shared and utilised.
• Business Advisory & Integration: Act as a trusted business partner and advisor on risk and internal controls, advising the business on the implications of changes in systems (e.g., ERP implementations), structures, and future M&A activities.
• Reporting & Issue Remediation: Draft high-quality reports that clearly articulate issues, business impact, and SMART action plans. Oversee and track the completion and remediation status of control issues and audit findings identified through both internal and external audits.
• External Audit Collaboration: Liaise and work closely with external auditors to drive increased reliance on internal controls and reduce the need for substantive testing.
• Continuous Improvement & Innovation: Drive continuous improvement in the company's control environment through technology, data analytics, and risk awareness, fostering a business culture that seeks ongoing enhancement in risk management and control effectiveness.
• Stakeholder Engagement & Culture: Build and maintain an effective stakeholder network across the organisation, contributing to a collaborative, professional work environment that encourages learning, innovation, and career development.
• Best Practice & Compliance: Maintain up-to-date knowledge of internal audit and controls best practices, regulatory requirements, financial reporting standards, and compliance programmes.

The essentials:

• ACA/CA/ACCA qualified or equivalent, with 5+ years of post-qualification/relevant audit experience.
• Pragmatic attitude with the ability to adapt quickly to a fast-paced, changing environment.
• Previous professional experience working in complex, international organisations is highly desirable.
• Technical accounting expertise and knowledge of professional internal audit practices, governance, risk management, and internal controls, backed by a strong track record of delivery.
• Strong written and verbal communication skills with a demonstrable ability to summarise and explain technical issues and solutions for a non-technical audience.
• Experience in designing and implementing processes and controls across financial and operational workflows.
• Understanding of COSO and other recognised risk and control frameworks.
