• Analyse cycle count coverage and prepare required SOX controls such as inventory reconciliations, production order aging, closing errors, and production variances.
• Support month-end processing, including engineering cost and project cost to support project accounting.
• Partner closely with the NZ Finance team to explain costing methodology and ensure clarity around financial impacts.
• Work with the US cost accounting team to align activities with corporate standards and policies.
• Collaborate with ERP teams to support testing, deployments, and continuous improvement initiatives.
• Provide training and user guides to finance and business users on costing processes, system functionality, and controls.

What You'll Bring:

• Strong analytical skills and a natural ability to interpret and explain complex information.
• Excellent attention to detail, organisational capability, and prioritisation skills.
• Proven variance analysis and independent problem-solving skills.
• Experience ensuring compliance with GAAP or IFRS.
• Advanced Excel proficiency and solid Microsoft Office capability.
• Bachelor's degree in accounting (or relevant equivalent experience).
• At least five years' experience in general ledger and cost accounting.
