The Opportunity

We're seeking a Geotechnical Engineer to join our Construction Phase Services team in Sydney. This is a primarily site-based junior role, with 4-5 days a week on site, giving you hands-on exposure to projects as they move from design into construction.

Key Responsibilities

- Liaise directly with clients, contractors and project teams to prepare inspection reports, technical correspondence and construction-phase recommendations to resolve geotechnical issues on site
- Manage multiple inspections, projects and client requirements with support from senior engineers

- Identify unexpected ground conditions and assist with developing practical remediation solutions
- Progressively develop technical, construction and client-management skills with support from experienced geotechnical engineers
- Plan and coordinate fieldwork, including subcontractor engagement and preparation of documentation to support safe, efficient site operations.
- Schedule laboratory testing programs and assist with the collation and interpretation of results, with guidance and review from senior staff.
- Assist with geotechnical analysis and provide practical input on foundations, retaining structures, slopes, pavements and earthworks.
- Communicate clearly with internal teams and clients on site, seeking support and feedback from senior team members as needed.
