Geologist/Geophysicist II

AECOM’s growing Water business is seeking a motivated Geologist/Geophysicist II to join our Geotechnical and Geophysics Group in Germantown, Maryland.

This position offers a unique combination of field investigation, technical analysis, and office-based project work. Team members participate in projects from field data collection through data processing, interpretation, mapping, and development of technical deliverables. The successful candidate will have opportunities to develop experience across multiple geophysical and geoscience disciplines while working alongside experienced geologists, geophysicists, engineers, surveyors, and GIS professionals.

The position is based in our Germantown, Maryland office and includes a combination of office and field assignments. While this is primarily an in-person position, hybrid work opportunities may be available following completion of the initial training period and once the employee has demonstrated the ability to work effectively and independently. Depending on project needs, up to approximately 50% travel may be required for field investigations, although the balance between field and office work will vary throughout the year. Field assignments may range from local day trips to occasional multi-week assignments throughout the United States and abroad.

Prior geophysics experience is beneficial but is not required. We place a high value on technical aptitude, curiosity, initiative, dependability, and a willingness to learn. The successful candidate should enjoy both solving technical problems in the office and being actively involved in collecting high-quality data in the field.

Our team supports a broad range of engineering and infrastructure projects involving renewable energy, pumped-storage facilities, tunnels, defense facilities, dams, data centers, bridges, roadways, and other complex infrastructure. This position provides exposure to projects ranging from initial site characterization through engineering design and construction.

This position is expected to begin in September 2026.

The job responsibilities of the position will include but are not limited to:

• Supporting geophysical investigations from field data acquisition through processing, interpretation, mapping, and reporting.
• Supporting terrestrial, marine, and borehole investigations using methods including seismic refraction/reflection, MASW, ground penetrating radar (GPR), electromagnetics, magnetics, electrical resistivity imaging, utility mapping, borehole geophysical logging, downhole/cross hole seismic, bathymetric surveying, side-scan sonar, sub-bottom profiling, and marine magnetics and seismic.
• Performing technical office work including geophysical data processing and interpretation, GIS analysis and mapping, CAD development, data management, quality control, technical documentation, and report preparation.
• Performing field investigations, including setup and operation of specialized geophysical and survey instrumentation, deployment of sensors and cables, operation of seismic sources, field data quality control, troubleshooting, and equipment mobilization.
• Supporting geodetic, geological, and geotechnical services including surveying, GIS mapping, geologic mapping, vibration and settlement monitoring, soil borings, and rock coring.
• Operating specialized geophysical, survey, and data-acquisition equipment and progressively developing the skills necessary to independently perform increasingly complex field and office assignments.
• Conducting specific phases of projects and assigned field activities under the general supervision of a Project Manager or senior technical team member.
• Evaluating field data in real time, identifying potential problems or unexpected conditions, and working with senior staff to determine appropriate solutions.
• Reviewing collected data for completeness and quality and identifying data that may require additional investigation or collection.
• Maintaining organized field documentation and digital data and performing appropriate quality-control checks.
• Preparing technical documentation, figures, maps, summaries, and portions of technical reports.
• Working collaboratively as part of multidisciplinary project teams and small field crews.
• Traveling up to approximately 50% as project needs require.
• Taking ownership of assigned tasks and progressively assuming greater responsibility for field activities and technical assignments.
