The Role

We're on the lookout for an experienced Senior or Principal Hydrogeologist to lead complex groundwater projects across NSW.

• Contribute to and manage the proposal process, including fee estimates and client liaison
• Attend and contribute to internal project meetings and external stakeholder discussions
• Apply hydrogeological analysis software, including MODFLOW, PLAXIS, SEEP/W
• Maintain up-to-date knowledge of NSW water legislation, WaterNSW and DCCEEW requirements

What We're Looking For

• A seasoned hydrogeologist with proven experience in both fieldwork and groundwater modelling
• Strong grasp of hydrogeological software and conceptual modelling
• A collaborative leader who can juggle technical depth with project oversight
• Familiarity with the NSW regulatory landscape, particularly water licensing and compliance
• Exceptional written and verbal communication skills — you're as comfortable writing reports as you are in front of a client

• Work with a tight-knit, technically elite team doing meaningful work
• Central Pyrmont office with collaborative leadership and flexible working culture
• Long-term career development with autonomy and genuine impact
• Access to exciting projects in the infrastructure, development and environmental sectors
