Estimator / Contract Administrator (012-1261)

​​Looking for Philippines-based candidates

Job Role: Estimator / Contract Administrator

Compensation range: $1,800 AUD - $2,500 AUD / Monthly

Engagement type: Independent Contractor Agreement

Work Schedule: This role is expected to align with the AU business hours (approx. 9 AM - 5 PM, Monday to Friday) for collaboration, but as a contractor, you’ll have flexibility in how you manage your time.

Who We Are: At Hunt St , we help Australian companies hire top remote talent in the Philippines. For this role, you will be engaged directly by the client as an independent contractor. We are not an outsourcing agency. All of our roles are 100% remote so you'll be able to work from home.

Who The Client Is: Our client is a civil construction and earthworks contractor providing site preparation, excavation, land clearing, and heavy equipment solutions for residential, commercial, and infrastructure projects. They deliver end-to-end groundworks services, combining modern equipment with experienced operators to support projects of all sizes.

Role Overview: The Estimator / Contract Administrator will support the company across the full commercial lifecycle—from reviewing tender opportunities and preparing accurate earthworks prices through to administering awarded projects.

This is a practical, commercially focused hybrid role, initially weighted approximately 70% estimating and 30% contract administration. The successful candidate will understand how civil earthworks are priced and delivered onsite, identify commercial risk before it becomes a problem, and maintain clear records throughout the project.

The role will work closely with company management, builders, suppliers, site supervisors and subcontractors to protect margins, clarify scope and ensure projects are commercially controlled from tender through final account.
