How much do assistant geotechnical engineer jobs pay per year?

As of Jul 19, 2026, the average yearly pay for assistant geotechnical engineer in the United States is $92,871.00, according to ZipRecruiter salary data. Most workers in this role earn between $71,000.00 and $109,000.00 per year, depending on experience, location, and employer.

What are some typical projects and tasks an Assistant Geotechnical Engineer handles in their first year?

As an Assistant Geotechnical Engineer, you will often be involved in site investigations, soil sampling, and laboratory testing during your initial year. You may assist in preparing technical reports and supporting senior engineers with design calculations for foundations, slopes, or retaining structures. Expect frequent collaboration with field crews, project managers, and other engineering disciplines, as well as the opportunity to visit construction sites to observe ground conditions and collect data. This hands-on involvement helps build a solid foundation for further professional growth in geotechnical engineering.

What are the key skills and qualifications needed to thrive as an Assistant Geotechnical Engineer, and why are they important?

To thrive as an Assistant Geotechnical Engineer, you need a solid background in civil or geotechnical engineering, typically supported by a relevant degree and knowledge of soil mechanics and foundation design. Familiarity with industry-standard software such as AutoCAD, PLAXIS, or GeoStudio, as well as experience with field testing equipment, is beneficial. Strong analytical thinking, attention to detail, and effective communication skills help you interpret data and collaborate with multidisciplinary teams. These skills and qualities ensure accurate site assessments, safe design solutions, and successful project execution.

What is the difference between Assistant Geotechnical Engineer vs Geotechnical Engineer?

AspectAssistant Geotechnical EngineerGeotechnical Engineer
Required CredentialsBachelor's degree in Civil or Geotechnical Engineering; some roles may require internship experienceBachelor's or Master's degree; professional engineering license may be preferred or required
Work EnvironmentSupport role in field and office; assisting with site investigations and report preparationLeading site assessments, designing geotechnical solutions, and overseeing projects
Employer & Industry UsageCommon in consulting firms, construction, and engineering companiesUsed in similar settings, often with more responsibility and project management duties

The main difference between an Assistant Geotechnical Engineer and a Geotechnical Engineer lies in experience and responsibilities. The assistant role typically involves supporting tasks under supervision, while the geotechnical engineer takes on more independent project management and design responsibilities. Both roles require relevant degrees, but the geotechnical engineer often holds a professional license and has more advanced expertise.

What does an Assistant Geotechnical Engineer do?

An Assistant Geotechnical Engineer supports senior engineers in investigating and analyzing soil, rock, and groundwater conditions at construction sites. Their work involves site inspections, collecting soil samples, conducting laboratory tests, and helping to prepare geotechnical reports. They assist in designing foundations, retaining walls, and other structures based on site-specific geotechnical data. Additionally, they ensure that construction projects comply with safety and environmental regulations by monitoring ground conditions and providing technical advice.

  • Prepare geotechnical reports, including boring logs, figures, and recommendations
  • Assist in proposal preparation, including scope development and cost estimates
  • Coordinate with field personnel, drillers, laboratory teams, and subcontractors during investigations
  • Perform site visits during construction oversight to observe conditions and ongoing construction activities with respect to Twining’s role
  • Travel to project sites and provide field support during construction, including coordinating with inspectors and contractors, reviewing field conditions, documenting observations, and assisting in resolving field-related geotechnical issues
  • Assist in on-site project coordination and participate in project meetings with clients, contractors, and design teams
  • Participate in construction observation activities (e.g., grading, foundation excavations, pile installation) as needed
  • Support client interactions and assist with business development efforts, including attending meetings and industry events
Requirements:
  • Bachelor’s degree in Civil Engineering (master’s degree with geotechnical emphasis preferred)
  • Minimum of 4 to 8 years of geotechnical engineering experience
  • Active California Professional Engineer (PE) license; GE license preferred
  • Strong foundation in geotechnical investigation, analysis, and reporting
  • Exposure to transportation or public agency projects (e.g., Caltrans, DSA, HCAI, counties/cities) preferred
  • Familiarity with geotechnical software such as Slide, LPile, or similar tools
  • Experience with common geotechnical analyses (bearing capacity, settlement, slope stability)
  • Basic understanding of seismic design considerations in California, including development of seismic design parameters and liquefaction analyses
  • Strong technical writing and analytical skills
  • Ability to work collaboratively in a team environment
  • Willingness to learn and take on increasing responsibility
  • Good communication skills with internal teams and clients
  • Willingness to engage in professional group meetings and potential client meetings to market Twining’s services
