Payroll Officer

The Payroll Officer will join IMC’s Finance team in Sydney, working directly with the Payroll Manager to execute and govern payroll across 5+ APAC jurisdictions, supporting approximately 350+ employees. The role sits within a lean, two-person payroll team and plays a critical part in ensuring payroll across IMC’s APAC operations runs accurately, compliantly, and on time.

A key near-term priority is supporting the global payroll migration to Neeyamo; a significant transformation project that will give you hands-on experience in system implementation, data validation, and cross-regional coordination. Beyond the migration, this is a broad and substantive role from day one in a lean, high-performing team where you will own real outcomes rather than support a large department.

Your Core Responsibilities

Payroll Execution

Execute end-to-end APAC payroll on a monthly cycle

Process payroll mutations: new starters, terminations, salary changes, allowances, and one-off payments - accurately and on time

Maintain and reconcile payroll records, verify payroll data, and resolve discrepancies before payroll close

Manage payroll overpayments end-to-end, including investigations, recovery processes, and repayment arrangements

Prepare payroll journals and reconciliations for posting to the GL in Workday

Statutory & Compliance

Manage Australian statutory payroll obligations, including Single Touch Payroll (STP), Payday Super (effective July 2026), payroll tax across applicable states, and superannuation

Support Hong Kong MPF, Korea social insurance, and other jurisdiction-specific payroll compliance obligations

Ensure payroll setup meets company requirements and records are aligned to policy and regulatory guidelines across all entities

Support tax and finance teams with payroll-related data for BAS, FBT, and year-end statutory reporting

Global Payroll Migration to Neeyamo

Play an active role in IMC’s global payroll migration to Neeyamo, validating data, supporting UAT, coordinating with regional teams, and ensuring a smooth transition without payroll disruption

Stakeholder & Team

Partner with HR, Finance, and regional teams to ensure payroll inputs are accurate, timely, and complete

Respond to employee payroll queries promptly and professionally; this is a service function and accuracy of communication matters as much as accuracy of processing

Support the Payroll Manager across ad hoc projects, system improvements, and process automation initiatives
