Leidos Analysis Solutions Group is seeking a Geotechnical Engineer to support geologic and geotechnical analysis for the reverse engineering of underground and hardened facilities. This role focuses on evaluating the properties of soil and rock to help characterize above- and below-ground structures and the surrounding geology.

The successful candidate will join a multidisciplinary team developing methodologies, processes, and technical applications for modeling and assessing complex facilities in support of mission-critical government work. This position offers the opportunity to apply deep technical expertise to challenging, high-impact problems in a fast-paced, high-energy government environment.

What You’ll Do

• Solve highly complex problems through technical analysis, reasoning, and interpretation.

• Conduct geotechnical evaluations using open-source information, commercial and classified imagery, and intelligence reporting to assess key geological attributes.

• Use geospatial tools such as ArcGIS Pro and ArcGIS Enterprise to analyze and document site geology and geotechnical characteristics.

• Prepare briefings and technical reports to communicate findings to customers and colleagues.

• Provide scientific, technical, and systems engineering support for the development of technologies and techniques, including sensors and sensor systems, used to identify and assess geotechnical properties in denied areas.

• Plan and execute field surveys and data collection efforts.

• Apply geological expertise to the collection and interpretation of borehole data, soil assessments, and fault studies.

• Produce technical reports and conduct field research at sites across the U.S. and worldwide.

• Recommend and develop new technical solutions, products, and standards that support mission objectives.

• Brief team members and senior officials on capability trends, analysis, and findings.

Required Qualifications

• Clearance Required: Candidates for consideration must possess an in-scope and active TS/SCI Polygraph clearance and the ability/willingness to maintain this clearance while holding this position. U.S. Citizenship is required.

• ​BS degree and 8+ years of relevant experience, or master’s degree and 6+ years of relevant experience in Engineering Geology, Geology, or Mining/Geotechnical Engineering.

• Strong background in geomechanics, computer modeling, field geophysics, and tunnel/slope rock mass characterization.

• Advanced knowledge of geotechnical software such as PLAXIS, SLOPE/W (GeoStudio), LPILE, gINT, and Slide.

• Experience with GIS tools and data, including ArcGIS Pro and ArcGIS Enterprise, and familiarity with MATLAB.

• Experience conducting geotechnical research and field collection.

• Experience in drilling, core logging, mining, tunnel construction and design, trenchless technology, rock mass characterization, and intelligence analysis.

• Excellent written and verbal communication skills, including the ability to brief and interact with senior officials.

• Expert-level knowledge of advanced technical principles, theories, and concepts.

Preferred Qualifications

• Professional Geologist (PG) or Professional Engineer (PE) accreditation.

• Military or defense-related experience.

• Experience with remote sensing applications related to geological or geotechnical analysis.

• Working knowledge of weapons effects and geologic material response under dynamic loading.

• Experience conducting geologic and geophysical fieldwork and data processing, including seismic and GPR investigations.
