As an Experienced Geo / Field Technician, you’ll take the lead on delivering high-quality geotechnical outcomes across a wide range of projects — from residential slabs to complex commercial and modular builds. This is a hands-on, field-based role for someone who already knows their way around a nuclear density gauge and a drill rig, and is ready to take on greater technical ownership, mentor junior staff, and be the trusted point of contact on site.

You’ll work across diverse ground conditions throughout NSW, operating drill rigs and compaction equipment alongside heavy machinery, with 4WD site access to some of the state’s most varied and challenging terrain. You’ll also play a key role in maintaining the technical and quality standards that underpin IdealCorp’s NATA-accredited laboratory and reputation as a market leader.

This is the right move for an experienced technician who wants more autonomy, more responsibility, and a genuine pathway into supervisory or senior technical roles.

• Oversee and verify cut and fill works in accordance with AS 3798, signing off compliance where required

• Conduct DCP, moisture, and compaction testing, interpreting results to identify site risks or non-conformances
• Collect and log soil samples, ensuring chain-of-custody and NATA-compliant documentation standards
• Perform and review laboratory testing including moisture content, sieve analysis, and Proctor compaction (AS 1289 series)
• Mentor and supervise junior field technicians, providing on-the-job training and quality checks
• Liaise directly with site supervisors, engineers, and clients to resolve field issues in real time
• Maintain accurate, audit-ready records and drive compliance with safety and quality systems
• Identify and lead process improvements, contributing to IdealCorp’s continuous improvement culture
