Geotech Research Engineer: Seawater Dilution & Modelling

National University of Singapore; Singapore; On-site; SGD 60,000 - 90,000; Full time

Job summary

The National University of Singapore invites applications for a Research Engineer in Geotechnical Engineering. The role focuses on studying active dilution of seawater using pumping systems with rainfall replenishment in sand-filled reclaimed land, using 1-g physical modeling and coupled groundwater flow/solute transport analyses. Strong lab skills and programming help are essential for modeling and simulations. The position is fixed-term and based in Singapore.

Qualifications

• Bachelor's degree in civil engineering or closely related field.
• Experience with physical laboratory testing and soil mechanics is preferred.
• Familiarity with numerical simulation software (COMSOL, SEAWAT, MODFLOW) or coding (Python, MATLAB) is an advantage.
• Strong written and verbal communication skills.
• Open to fixed-term contract.

Responsibilities

• Construct and manage a 1-g physical model box representing Singapore's reclaimed land stratigraphy.
• Install and calibrate sensors and flow visualization tools; collect and monitor data.
• Develop analytical drawdown trajectory models and numerical groundwater flow/solute transport models.
• Perform field-scale simulations to evaluate dilution efficiency under varying soils.
• Prepare progress reports and present findings in journals and conferences.
