A Geotechnical Engineer specializes in understanding and assessing the physical, mechanical and chemical properties of earth materials. They study the properties of these materials to assess their suitability for construction projects and to design foundations, slopes, retaining walls, and other structures to ensure stability and safety. Investigates geological conditions, conducts tests on rock and soil, and provides recommendations to mitigate risks, ensuring the integrity and longevity of infrastructure projects.
This role is primarily field-based; the majority of the work involves on-site supervision of pile installation and testing, ground improvement (including prefabricated vertical/wick drains and surcharge), geotechnical instrumentation and settlement monitoring, and earthwork and backfill quality control. The position is part of the Geotechnical & Hydraulic Engineering Services (G&HES) group. The successful candidate will report to and receive technical supervision and functional oversight from the G&HES Group Supervisor / Geotechnical Engineering Manager or their designee, and is expected to work independently in the field while coordinating closely with Construction, CSAOM, ES&H, piling and marine subcontractors, the site-investigation contractor, and the project management team. The role is site-based at the Port Arthur LNG project for an extended duration, with potential transition to another Client project or permanent office thereafter, and may require travel to other Client and client offices within the U.S. Excellent verbal and written communication skills and a commitment to Client diversity & inclusion, leadership, quality, and safety values are required.
Major Responsibilities:
This field-based role provides on-site engineering support and supervision for geotechnical construction on the Port Arthur LNG project, in accordance with applicable procedures, codes, standards, and contract requirements. Specific tasks will include (but are not limited to): Site Investigation & Geotechnical Instrumentation Coordinate and oversee field investigation and in-situ testing performed by the geotechnical site-investigation contractor — soil borings, cone penetration tests (CPT/CPTu), and sampling — and review the resulting data. Install, monitor, and interpret geotechnical instrumentation — settlement plates/gauges, piezometers, and inclinometers — and maintain settlement-monitoring records for construction control. Deep Foundations Works Provide on-site supervision of driven-pile installation (steel pipe and H-piles), verifying pile location, alignment, plumbness, embedment, and driving criteria against approved drawings and specifications. Witness dynamic pile testing (PDA/CAPWAP) and static load tests, verify driveability against wave-equation criteria (e.g., GRLWEAP), and review pile driving records for capacity and refusal. Support installation of steel sheet piles and helical piles where used, including verification of tolerances and installation records. Ground Improvement & Settlement Mitigation Provide on-site supervision of ground improvement of compressible soils — prefabricated vertical (wick) drains, surcharge/preload placement, and soil stabilization (cement/lime treatment) — and verify installation against specification. Monitor consolidation and settlement during surcharge, interpret instrumentation trends, and coordinate surcharge-removal timing with home-office engineering. Earthwork, Underground Utilities & Site Civil Inspect and approve subgrade preparation, structural fill placement, moisture conditioning, lift thickness, and compaction, including proof-rolling of exposed subgrade. Oversee excavation, bedding, and backfill compaction for underground utilities (including gravity sewers), and coordinate dewatering and excavation support as required. Review field and laboratory test results (density, gradation, moisture) and coordinate remediation of non-conforming areas with engineering and Construction. General Field Engineering Identify construction issues or deviations early and coordinate corrective actions with Construction, subcontractors, and home-office engineering. Maintain field documentation, including daily reports, inspection records, nonconformance reports (NCRs), and quality records. Prepare daily geotechnical reports documenting field observations, testing results, and instrumentation readings for construction quality control and project documentation. Ensure all construction activities are carried out in full accordance with project specifications, engineering drawings, and applicable codes, standards, and regulations.
Education and Experience Requirements:
An M.S. degree in Geotechnical Engineering from an accredited university with a minimum of 5 years of relevant work experience, or a Ph.D. in Geotechnical Engineering with a minimum of 3 years of relevant work experience. Engineer-in-Training (EIT) certification.
Required Knowledge and Skills:
Minimum Qualifications Demonstrated field experience supporting or supervising deep foundation (driven pile) construction and ground improvement of soft/compressible soils. Field experience with pile driving observation and testing (PDA/CAPWAP and/or static load tests) and pile driveability evaluation. Working knowledge of ground improvement (prefabricated vertical/wick drains, surcharge/preloading, and soil stabilization), g
