Job Overview by Ladders

Qualifications

  • M.S. or Ph.D. in Geophysics, Applied Mathematics, Physics, Computer Science, or a related quantitative field.
  • Minimum 5 years of hands-on experience with full-waveform inversion (FWI) on real seismic data.
  • Demonstrated experience applying machine learning to geophysical or physics-based scientific problems.
  • Working knowledge of seismic imaging, wave propagation, inverse problems, and optimization methods.
  • Proficiency in Python and practical experience with PyTorch for ML tasks.
  • Experience handling large scientific datasets and computational workflows.
  • Strong scientific judgment in designing comparisons and communicating uncertainty.

Responsibilities

  • Develop ML and hybrid physics-ML methods for seismic imaging and inversion.
  • Apply advanced machine learning techniques to geophysical challenges such as denoising and image enhancement.
  • Build workflows for large multidimensional seismic datasets utilizing GPU and cloud infrastructure.
  • Validate ML methods against conventional physics-based approaches.
  • Transition successful prototypes into production workflows with proper documentation.
  • Communicate results to geophysicists, data scientists, and asset teams.

Benefits

  • Work in a collaborative and innovative environment within the Subsurface Innovation Imaging Team.
  • Opportunity to work on cutting-edge seismic imaging and machine learning technologies.

  • Engagement with a diverse team of experts in geophysics and data science.
  • Potential for professional development and contributing to impactful geophysical projects.
Full Job Description
We are looking for a motivated individual to fill the position of Machine Learning Expert within our Subsurface Innovation Imaging Team based in Houston, TX.

Essential Job Responsibilities:

  • Develop ML and hybrid physics-ML methods for seismic imaging, inversion, and velocity model building — including ML-assisted RTM, LSRTM, and FWI.

  • Apply deep learning, generative models, neural operators, and physics-informed approaches to problems such as denoising, interpolation, image enhancement, model prediction, uncertainty estimation, and automated interpretation.

  • Build workflows that handle large multidimensional seismic datasets on GPU and cloud infrastructure.

  • Validate new methods against established physics-based approaches, and make an evidence-based case for where they add value and where they do not.

  • Move successful prototypes into production imaging workflows, with the documentation and reproducibility that requires.

  • Communicate results clearly to geophysicists, data scientists, and asset teams.

Qualifications:

  • M.S. or Ph.D. in Geophysics, Applied Mathematics, Physics, Computer Science, or a related quantitative field.

  • Minimum 5 years of hands-on (post academic) FWI experience: you have personally run full-waveform inversion on real seismic data. Familiarity with FWI from coursework or literature alone is not sufficient for this role.

  • Demonstrated experience applying machine learning to geophysical or other physics-based scientific problems.

  • Working knowledge of seismic imaging and the numerical methods behind it: wave propagation, inverse problems, and optimization.

  • Proficiency in Python and hands-on experience with PyTorch, including training, validation, and performance evaluation.

  • Experience working with large scientific datasets and computational workflows.

  • Sound scientific judgment: the ability to design a fair comparison, recognize a result that is too good to be true, and communicate uncertainty honestly.

Additional Desired Qualifications:

  • Experience with neural operators, implicit neural representations, generative models, or physics-informed neural networks applied to wave-equation problems.

  • Experience combining wave physics with ML, including differentiable modeling and inversion.

  • Uncertainty quantification, surrogate modeling, or ML-assisted optimization for expensive geophysical workflows.

  • GPU, HPC, or distributed computing experience; AWS in particular.

  • Experience with offshore or Gulf of America seismic data.

  • Effective use of AI-assisted coding tools to accelerate development and debugging of scientific workflows.

  • A record of research prototypes that reached production use.

Occidental does not offer sponsorship of employment-based nonimmigrant visa petitions for this role.
