Internal Audit Manager - Sydney

About the role

Join a 2026 AFR BOSS Best Places to Work Gold Winner and 2026 Sustainability Champion recognised by the World Steel Association. Play a key role in shaping our performance across our InfraBuild business.

At InfraBuild, Internal Audit is more than compliance. It is a strategic function that partners with senior leadership to strengthen governance, improve operational performance, enhance risk maturity, and influence business outcomes across one of Australia’s largest integrated industrial organisations.

Based in our modern Sydney CBD office, this is a high-impact opportunity for an experienced audit professional who thrives in complex environments and wants genuine visibility across executive stakeholders, operations, and transformational initiatives.

You’ll work across a diverse national business spanning manufacturing, recycling, infrastructure, logistics and distribution, gaining exposure to operational, financial, strategic and emerging risk landscapes in an organisation committed to sustainability and continuous improvement.

What you will be doing:

• Contribute to and execute a risk-based Internal Audit plan within a large, highly complex organisation with diverse and evolving business processes
• Lead end-to-end audits across operational, financial, compliance, and strategic risk areas, taking full ownership from planning through to reporting and stakeholder presentation
• Apply a creative, flexible auditing approach where processes vary significantly—even within the same business unit—moving beyond a checklist-driven mindset
• Evaluate the effectiveness of governance, risk management, and internal control frameworks, delivering clear, commercially relevant insights and recommendations
• Present findings confidently to senior leadership and partner with stakeholders to drive practical remediation, continuous improvement, and value-adding outcomes
• Build strong relationships across corporate and operational teams nationally, while influencing and supporting business improvements
• Operate with a high degree of autonomy, with significant opportunity to contribute to consulting-style, value-add advisory work

 You will be rewarded with:

• Hybrid and flexible working arrangements
• Brand new Sydney CBD corporate office
• Exposure to senior executives and complex national operations
• Diverse audit portfolio across manufacturing, infrastructure, recycling and distribution
• Long-term career development opportunities within a large national organisation

Primary Benefits:

We offer a range of benefits designed to support you at work and beyond:
 

• Paid parental leave that goes further - 20 weeks paid Primary Carer Leave and 3 weeks Partner Leave, plus superannuation contributions during unpaid leave (eligibility applies)

• Health cover at discounted rates - Access corporate rates with nib Health Insurance to support you and your family

• Everyday savings - Access a wide range of employee discounts across major brands including retail, travel and lifestyle

• Flexible vehicle options - Novated leasing options available, providing a tax-effective way to finance and manage your vehicle

• Support when you need it - Confidential counselling and wellbeing support through our Employee Assistance Program (EAP) and Sonder, available to you and your immediate family

What you will bring:

This is an opportunity to step into a highly visible role where your work directly influences decision-making and business performance.

You’ll join an organisation that values strong governance, invests in sustainability, and operates at significant scale and complexity — offering the breadth of exposure many audit professionals seek but rarely find.

• Significant Internal Audit experience within large, complex organisations
• Experience across industrial, manufacturing, infrastructure, engineering or similarly operational environments will be highly regarded
• Strong capability in risk assessment, control evaluation and audit execution
• Exceptional report writing and stakeholder communication skills
• Ability to translate complex findings into pragmatic, commercially relevant recommendations
• Confidence engaging with senior leaders and influencing outcomes across multiple stakeholder groups
• Strong organisational skills with the ability to manage multiple audits and competing priorities simultaneously
• A collaborative, curious and improvement-focused mindset.
