Job brief

We are seeking a detail-oriented Geotechnical Engineer to join our infrastructure design team and lead subsurface analysis for high-profile civil engineering projects. In this role, you will bridge the gap between geological data and structural design, providing the technical foundation for bridges, tunnels, and commercial foundations. You will work closely with project managers and field crews to translate site-specific findings into actionable construction recommendations. If you are passionate about soil mechanics and enjoy solving complex subsurface challenges, we want you to help us build safer, more resilient structures.

Key highlights

Conduct comprehensive site investigations including borehole logging, cone penetration testing (CPT), and standard penetration testing (SPT) to assess subsurface conditions.
Perform advanced geotechnical analysis such as slope stability, seepage, and settlement calculations using software like GeoStudio or PLAXIS.
Design shallow and deep foundation systems, including pile foundations and mat slabs, to support vertical and lateral loads for major structures.
Develop detailed geotechnical investigation reports and engineering recommendations that comply with AASHTO, IBC, and local building codes.

What is a Geotechnical Engineer?

A Geotechnical Engineer is a specialized civil engineering professional who evaluates the behavior of earth materials to ensure safe and stable infrastructure development. By applying principles of soil mechanics, rock mechanics, and hydrogeology, a Geotechnical Engineer assesses site conditions to provide critical data for foundations, retaining structures, and embankments. Their expertise in numerical modeling and field exploration is fundamental to mitigating risks associated with seismic activity, slope stability, and groundwater control in large-scale construction projects.

What does a Geotechnical Engineer do?

A Geotechnical Engineer spends their time conducting site investigations, interpreting borehole logs, and performing laboratory testing to characterize subsurface conditions. They utilize sophisticated software like GeoStudio, PLAXIS, or gINT to run complex finite element analyses and calculate settlement, bearing capacity, and lateral earth pressures. On-site, they supervise geotechnical drilling programs and perform in-situ testing, ensuring that final engineering designs meet strict building codes and environmental safety standards while collaborating with structural engineers and contractors.

Key responsibilities

Conduct comprehensive site investigations including borehole logging, cone penetration testing (CPT), and standard penetration testing (SPT) to assess subsurface conditions.

Develop detailed geotechnical investigation reports and engineering recommendations that comply with AASHTO, IBC, and local building codes.
Collaborate with structural engineering teams to provide soil design parameters, earth pressure coefficients, and seismic site classification data.
Monitor construction activities including earthwork compaction, foundation excavation, and deep foundation installation to ensure adherence to technical specifications.
Manage laboratory testing schedules for soil samples to determine shear strength, permeability, compressibility, and chemical composition for environmental compliance.
Coordinate with environmental consultants and regulatory agencies to mitigate risks related to soil contamination and groundwater management during project phases.

Requirements and skills

Bachelor’s degree in Civil Engineering or Geological Engineering, with a specific focus on geotechnical coursework.
Professional Engineer (PE) license or current status as an Engineering Intern (EIT) working toward licensure.
Proficiency in industry-standard geotechnical software such as PLAXIS, GeoStudio (SLOPE/W, SEEP/W), gINT, or Slide.
Demonstrated experience interpreting geotechnical borehole logs and laboratory test results for foundation design projects.
Solid understanding of soil mechanics, rock mechanics, and relevant ASTM and AASHTO testing standards for soil quality.
Strong technical writing skills for producing clear, actionable geotechnical reports for clients and municipal regulatory bodies.
Ability to travel to remote or active construction sites for field oversight, soil inspection, and project coordination.
Experience utilizing AutoCAD or Civil 3D for creating cross-sections, boring location plans, and structural foundation details.

FAQs

What does a Geotechnical Engineer do on a daily basis?

On a daily basis, a Geotechnical Engineer balances field exploration with office-based analytical work. This involves analyzing soil samples, running computer simulations to model slope stability or foundation settlement, and drafting technical reports that dictate how a building’s foundation will be built. They often communicate findings to structural engineers to ensure the proposed design can be safely supported by the ground conditions.

What are the essential skills for a Geotechnical Engineer?

Essential skills include a strong foundation in fluid mechanics and soil physics, proficiency in geotechnical modeling software like PLAXIS or GeoStudio, and the ability to interpret complex subsurface data. Strong technical writing is also critical, as Geotechnical Engineers must translate geological findings into clear recommendations for architects and contractors. Additionally, field experience conducting soil sampling and inspection is highly valued in this profession.

Who does a Geotechnical Engineer work with on construction projects?

Geotechnical Engineers work as a central hub between various stakeholders, including structural engineers, architects, project developers, and construction contractors. They also interact frequently with environmental consultants for soil contamination testing and with government regulatory authorities to secure building permits. Their collaboration ensures that the site conditions are understood and addressed before heavy construction begins.

Why is a Geotechnical Engineer important for infrastructure projects?

A Geotechnical Engineer is vital because they minimize the risks of building failure, such as foundation settlement, sinkholes, or slope collapse. By accurately characterizing the earth beneath a structure, they allow engineers to design cost-effective foundations that provide long-term stability. Their early involvement in a project often prevents budget-overrunning foundation issues and ensures that public and private infrastructure meets strict safety standards.
