About Us

At HDR, we specialize in engineering, architecture, environmental and construction services. While we are most well-known for adding beauty and structure to communities through high-performance buildings and smart infrastructure, we provide much more than that. We create an unshakable foundation for progress because our multidisciplinary teams also include scientists, economists, builders, analysts and artists. That's why we believe diversity is our greatest strength. HDR is proud to be an equal opportunity workplace and an affirmative action employer.

Primary Responsibilities

The Senior Trenchless Geotechnical Engineer will report to the Trenchless Engineering Manager, having primary responsibilities revolving around the planning, managing and orchestrating of geologic and geotechnical initiatives associated with trenchless technologies: engineering, design and construction applications.

The Senior Trenchless Geotechnical Engineer will contribute to the Trenchless Program by: utilizing experience and expertise to apply geologic information to engineering and design practices, including hydraulic fracture and inadvertent returns analyses; coordinating and executing front end information collection initiatives, such as geotechnical investigation programs for incorporation into critical engineering and design decisions and constructability evaluations; interpreting geological information to evaluate subsurface conditions for feasibility of design and construction; and addressing problematic subsurface conditions to provide recommendations for mitigation as needed throughout the lifecycle of trenchless projects (planning through construction). Data management, quality control of geological data, planning, resource forecasting, cost estimating, scheduling and risk management for all geological and geotechnical initiatives are also included in the primary responsibilities.

Field based responsibilities will primarily include site reconnaissance, oversight of geotechnical field investigations and oversight of trenchless pipeline installations.

While in the field, the Senior Trenchless Geotechnical Engineer will monitor and report on daily activities, run various geological field tests, interpret lab test results for soil and rock samples, provide maintenance of field test equipment, and present field data in a timely manner with a high level of quality.
