Geologic Modeler

Description

Leidos is seeking a Geologic Modeler to support hydrogeologic investigations, groundwater modeling, and environmental data visualization tasks for projects across the United States. The position can be remote (work from home) or based in Leidos offices in Twinsburg, Ohio; Bothell, Washington; Earth City, Missouri; or Reston, Virginia.

The Geologic Modeler will support and manage aspects of environmental investigation and remediation projects, including numerical modeling of groundwater, surface water, sediment transport, and/or related media; contaminant fate and transport modeling, data visualization (2D and 3D); trend analysis, task/project management; data analysis and interpretation; and report preparation.

The Geologic Modeler will work collaboratively with Leidos Project Managers, Senior and Junior Staff, and interface with multiple Leidos offices and subcontractors.

The Geologic Modeler will support environmental site characterization investigations and remediation projects, including development of 2D and 3D Conceptual Site Models (CSMs), geospatial analysis, numerical modeling of groundwater, contaminant fate and transport modeling, data visualization (2D and 3D); trend analysis, data analysis and interpretation; and report preparation. The Geologic Modeler will work collaboratively with Leidos Project Managers and Senior Staff, junior staff, and interface with multiple Leidos offices and subcontractors.

Must be able to travel domestically for client meetings and/or potential site visits up to 15% of the time.

Must be able to obtain access to, and conduct work on, U.S. Government installations. U.S. Citizenship or U.S. Permanent Resident status is required.

Primary Responsibilities:

• Execute project tasks as assigned, including geologic/hydrogeologic data analysis, 2D and 3D geologic modeling, groundwater elevation contouring, groundwater sampling plan design, developing CSMs

• Develop 2D cross-sections and 3D models to simulate site hydrogeology and contaminant distribution

• Support physical and/or numerical modeling of hydraulic/hydrologic processes related to contaminant fate and transport

• Develop visualizations to present complex model results

• Simulate and estimate physical, chemical, and biological processes related to contaminant fate and transport

• Compile, interpret, and report data to meet project quality assurance requirements under Federal (e.g. CERCLA), state, and/or client programs

• Support preparation of technical reports, including complex technical analysis, CSMs, and visual data presentations, including maps, cross sections, data tabulations, development, analysis, and selection of remedial alternatives

• Prepare and present project findings to internal project teams, clients, regulatory agencies, and the public

• Willing and able to travel to project locations and attend client meetings

What Sets You Apart:

• Bachelor's degree in geology, hydrogeology, mining engineering, environmental engineering, or relevant field and a minimum of 5 years' experience in the environmental field. A Master's degree and/or relevant certifications will be considered as experience.

• Proficiency in 3D data visualization software, e.g., C-Tech EVS, LeapFrog, EarthVision, or similar

• Proficiency in 2D data visualization software such as Surfer and/or GIS

• Interpretation and analysis of chemical, geotechnical, geologic, hydrogeologic, and/or engineering data to address project/reporting requirements

• Detailed knowledge of the hydrogeologic aspects of environmental site characterization and remediation including monitoring well design and construction; working knowledge of environmental sequence stratigraphy (ESS), groundwater sampling, groundwater flow, contaminant fate and transport, CSM development, fracture flow and preferential flow paths, and the relationship between geology

• Proficiency in MS Office tools (Excel, Word, Access, Outlook, Project, PowerPoint)

You Might Also Have:

• Master's degree in geology, hydrogeology, environmental engineering, or relevant field, and at least 7' years experience in environmental consulting with comprehensive experience in geologic modeling and hydrogeology.

• Proficiency in Environmental Sequence Stratigraphy (ESS)

  Proficiency in groundwater and surface water modeling including MODFLOW-USG/MODFLOW 6, Groundwater Vistas, Aqtesolv, pumping test analysis, and similar programs

• Specialized skills/experience in environmental regulatory requirements; environmental statistical methods (e.g., trend analysis) and software tools (e.g., SAS); environmental databases (e.g., data management); or commonly employed contaminant fate/transport models (e.g., SESOIL, AT123D, DUST)

• Licensure as a professional engineer and/or professional geologist

• Working knowledge of emerging PFAS technical guidance and investigations

• Prior completion of OSHA 1910.120 hazardous waste worker certification (40-hour HAZWOPER) and OSHA occupational physical exam and medical clearance allowing performance of field work at hazardous waste sites)

While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

The Leidos pay range for this job level is a general guideline onlyand not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.
