About the role

About the Opportunity

We are looking for an organised, approachable and hands-on HR and Office Administration Coordinator to join us in a flexible, part-time position. We understand that experienced people may be looking for a role that provides meaningful and compelling work while supporting a healthy work–life balance. We are therefore open to discussing flexible working hours, including hours structured around school or other personal commitments.

This opportunity may suit an experienced HR or administration professional returning to the workforce, seeking a better balance, or wanting to continue developing their HR experience in a supportive small-company environment.

The role combines HR administration, recruitment and onboarding support, employee record management, office coordination, support to the Directors and general administration. It is a practical and varied position where no two days will be exactly the same.

Because the role supports our employees, visitors and day-to-day office operations, it will be primarily based at our Lane Cove West office. The specific working days and hours can be discussed and agreed with the successful candidate.
