• Build and refine 3D structural models (Leapfrog, Move, or equivalent) to support conceptual reservoir models and drill planning
• Evaluate fault-related permeability potential and fracture connectivity using both field and subsurface datasetsWork closely with Exploration Geologists to synthesize geologic, geophysical, and geochemical inputs into robust conceptual models
• Collaborate with R&D to support the development and training of predictive models using structural and fault datasets
• Provide technical leadership and mentorship to junior geoscientists on structural geology methods and field techniques
• Contribute to generative exploration strategy by identifying high-potential structural settings for new prospect development
• Travel regularly to field sites across the western U.S. (30–40%) to lead structural mapping and support active drilling programs

Experience

• Expert-level knowledge in structural geology, with a focus on fault systems, fracture mechanics, and hydrothermal permeability
• M.S. or Ph.D. in structural geology, tectonics, geomechanics, or a related field
