We’re seeking a Senior Subject Matter Expert in Fault and Fracture Mapping to lead structural interpretation and field-based analysis across our growing geothermal exploration portfolio. Your work will directly shape where and how we drill by identifying and characterizing the structural controls on permeability that make geothermal systems viable. You’ll be a bridge between field geoscience and cutting-edge machine learning tools, helping us turn data into decisions that drive real megawatts onto the grid.  Outcomes – Problems you’ll solve  You will own the structural framework for Zanskar’s geothermal prospects. Your insights into fault kinematics, fracture networks, and stress regimes will reduce uncertainty, improve drilling outcomes, and accelerate project timelines. You’ll guide field programs to collect meaningful data, translate those findings into 3D geologic models, and work closely with both our Exploration Geologists and R&D team to continuously improve how we identify and characterize geothermal targets.

Responsibilities

• Serve as Zanskar’s technical lead for fault and fracture systems analysis across geothermal projects
• Conduct and lead field-based structural mapping campaigns to characterize fault geometries, surface expressions, and fracture attributes

• 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
• 7–10+ years of applied field and subsurface experience in structurally complex terrains (geothermal, mineral exploration, petroleum, or related industries)
• Advanced proficiency with 3D structural modeling tools (Leapfrog, Move, Petrel, or similar)
• Demonstrated excellence in field mapping and structural interpretation from multiple data sources
• Strong cross-disciplinary collaboration skills — able to communicate and integrate effectively with geologists, engineers, and data scientists
• Experience designing and executing field programs, managing logistics, and synthesizing results into exploration decisions
• Familiarity with geostatistics, geomechanical modeling, or ML/AI integration into geological workflows is a plus
• Comfortable operating in a fast-moving startup environment with evolving goals and high-impact work

Location and Benefits

• Paid holidays
• 15 days PTO + PTO accrual increase based on tenure
