Senior Geotechnical Engineer / Senior Engineering Geologist

We are seeking an Engineering Geologist/Geotechnical Engineer to support and lead components of ground investigations and geotechnical deliverables across civil, Defence, and infrastructure projects in Western Australia. This is a hands-on role suited to someone who is technically capable, field-experienced, and ready to take ownership of defined packages and work closely with senior staff.

Key responsibilities

• Plan and deliver ground investigations end-to-end, including scoping, methodology selection, scheduling, and coordination with drillers and specialist subcontractors.

• Undertake and/or supervise fieldwork (e.g., logging, sampling, in-situ testing oversight, QA of investigations) and ensure safe, compliant site execution.

• Complete engineering geology/geotechnical interpretation and reporting, including:

• Factual GI reports (logs, test schedules, QA summaries)

• Ground model development and parameter selection

• Geotechnical assessment inputs for design and construction (as required)

• Coordinate Laboratory testing programs and validate results for completeness and suitability.

• Apply strong quality and process discipline: checking, traceable calculations/assumptions, clear deliverable structure, and consistent record keeping.

• Contribute to multidisciplinary coordination with civil/structures/services teams (constructability, earthworks, pavements, drainage interfaces).

• Support client and stakeholder engagement, including briefings on findings, risks, and recommendations.
  

What we’re looking for

• 3–10 years post-graduate experience as an Engineering Geologist / Geotechnical Engineer.

• Minimum 2 years of ground investigation fieldwork experience (planning, supervision, logging/sampling, QA and safety).

• Strong preference for Western Australian experience, including familiarity with WA geotechnical investigation practices (local ground conditions, common investigation methods, and typical client/authority expectations).

• Sound technical writing skills and ability to produce clear, defensible deliverables.

• Proactive, organised, and detail-oriented with a genuine focus on quality.

• Exposure to Defence or high-assurance environments is advantageous (but not essential).
