Soil Tester Jobs (NOW HIRING)

The Soil Technician supports construction projects in the Seattle area by performing field and laboratory testing of soils, concrete, and asphalt. This role focuses on operating a nuclear density gauge to verify soil compaction, preparing and testing construction materials, and documenting findings in clear, detailed reports. It is an excellent opportunity for individuals who enjoy working outdoors, applying knowledge of engineering, geology, or construction in a hands-on environment.

Responsibilities

• Operate a nuclear density gauge to perform soil compaction testing on active construction sites.
• Conduct soil testing and soil sampling in the field and prepare samples for analysis.
• Perform testing of concrete and asphalt samples to support construction materials quality control.
• Record, analyze, and interpret test results accurately to assess soil density and material performance.
• Prepare clear, concise, and thorough written reports documenting field observations, test procedures, and results.
• Follow established procedures and safety protocols when using a nuclear density gauge and other testing equipment.
• Travel daily to construction sites in the Seattle area to perform field work as assigned.
• Coordinate daily activities by meeting at the office in the morning, organizing equipment and vehicles, and returning at the end of the workday.
• Support geotechnical and environmental field investigations by collecting, labeling, and handling soil and material samples properly.
• Communicate effectively with project team members to ensure testing meets project specifications and schedules.

• Minimum of 1 year of geotechnical or environmental field experience.
• Background in engineering, construction, geology, or a related field.
• Ability to operate, or willingness to learn to operate, a nuclear density gauge for soil compaction testing.
• Strong understanding of soil testing, soil sampling, and soil density analysis.
• Experience with construction materials testing, including soils, concrete, and asphalt.
• Proficiency in writing clear, accurate, and detailed technical reports.
• Ability to work safely and effectively in field environments on active construction sites.
• Nuclear Density Gauge certification completed prior to starting in the role.

• Education in engineering, geology, construction management, environmental science, or a closely related discipline.
• Prior experience with nuclear density gauges in geotechnical or construction settings.
• Familiarity with geotechnical and environmental field practices, including sampling and data collection.
• Strong attention to detail and ability to follow standardized testing procedures.
• Effective communication skills for coordinating with project teams and documenting field activities.
• Interest in developing a career in geotechnical, environmental, or construction materials testing.

The role is primarily field-based, supporting construction projects throughout the Seattle area. The workday typically begins at the office in Kirkland at 7:00 AM, where the team meets, prepares vehicles, and loads testing equipment before heading into the field. The day generally ends around 4:00 or 5:00 PM with the return of vehicles and equipment to the office. The Soil Technician works outdoors on active construction sites, performing hands-on testing of soils, concrete, and asphalt using a nuclear density gauge and other construction materials testing tools. The environment involves varied weather conditions, physical activity, and regular travel between the office and project locations. The organization offers a collaborative, small-firm setting that provides a broad range of environmental and geotechnical services, including geology, geophysics, groundwater, geotechnical engineering, and environmental assessments, creating opportunities for learning and professional growth.
