Geothermal energy is the most abundant renewable energy source on Earth—containing ~2,300× more energy than all fossil fuels combined. Yet despite this enormous potential, geothermal has historically been difficult, slow, and expensive to discover and develop.

At Zanskar, we are transforming geothermal exploration by combining geophysics, geology, and AI-driven modeling to dramatically increase discovery rates and reduce development risk. We operate at scale and at speed, setting new industry standards for how geothermal prospects are identified and de-risked.

To support this mission, we are hiring a Senior Computational Geophysicist with deep, hands‑on experience in electromagnetic and/or potential fields methods who can take real field data from active geothermal sites and turn it into defensible subsurface interpretations. This role is fundamentally about streamlining and automating inversion workflows that incorporate structural, lithological, and hydrothermal constraints: ensuring models reflect geological reality, not just a mathematical best‑fit.

• Lead and execute stochastic and traditional inversions on active geothermal sites, producing subsurface models that materially de‑risk drilling and development decisions
• Work extensively with electromagnetic and/or potential fields data, including:heli
  
  TEM,magnetotellurics (MT), gravity and gagnetic data
• Quantify uncertainty and assess model robustness in decision‑critical settings
• Integrate inversion results with geological models, structural interpretations, well data, and drilling outcomes
• Develop and maintain Python‑based tools and pipelines that automate inversion workflows, reduce manual overhead, and enable consistent, repeatable results across many sites
• Collaborate closely with geologists and ML researchers
• Communicate results clearly, including uncertainties, assumptions, and recommended next steps
• Contribute to patentable methods and tools that advance geothermal exploration

• Multiple years of hands‑on inversion experience on real‑world geothermal or subsurface projects, across multiple sites and datasets
• Direct experience with EM and/or potential fields methods (heli
  
  TEM, MT, gravity, and/or magnetics) from raw field data through to full inversion workflows
• Strong programming skills in Python, including experience building reproducible, maintainable scientific software; familiarity with inversion frameworks, numerical optimization, or HPC environments is a strong plus
• Experience implementing or modifying inversion algorithms, and comfort with stochastic, Bayesian, and regularization‑based approaches
• Solid physical intuition for geophysical observables and the ability to reconcile inversion results with geological, structural, and operational constraints
• Comfort operating under imperfect data, time pressure, and evolving site understanding
• Proven ability to collaborate across disciplines: geologists, field teams, ML researchers, and business leaders, and communicate clearly about what the data supports, what it doesn't, and where uncertainty matters
