About the Job

Requirements

  • A Master's or PhD in Artificial Intelligence, Machine Learning, Physics, Applied Mathematics, or a related field, with a strong AI/ML research focus and scientific computing background.
  • For Master's degree holders, 1–3 years of work or research experience in scientific machine learning or applied artificial intelligence roles; PhD holders have no minimum work experience requirement.
  • Research depth demonstrated through peer-reviewed publications, strong PhD research, or significant open-source scientific machine learning contributions.
  • Expert-level research implementation capability in PyTorch or JAX.
  • Ability to design PINNs methodology, physics-constrained loss function architectures, and digital twin models.
  • Expertise in at least one of the following areas: Bayesian deep learning, Bayesian experimental design, active learning acquisition function design, ensemble uncertainty quantification, structural causal models, causal discovery, or causal inference for reliability and yield root cause analysis.
  • Research output in at least one primary area, demonstrated through a publication, preprint, PhD thesis chapter, or significant open-source scientific machine learning contribution.
  • Ability to produce validated research prototypes with complete technical documentation.

Responsibilities

  • Originate and advance PINNs methodology, design physics-constrained loss function architectures, validate digital twin machine learning components against domain physics with the storage domain expert, and deliver validated prototypes with complete technical documentation for implementation.
  • Lead research into Bayesian deep learning, active learning acquisition function design, ensemble uncertainty methods, and Bayesian experimental design frameworks for autonomous experiment selection; transfer validated acquisition function designs for active learning pipeline integration.
  • Own causal inference framework product development for reliability root cause analysis, including structural causal model design, causal discovery, and causal intervention planning for product development improvement.
  • Design physics-constrained generative model approaches, including diffusion models and variational autoencoders, for synthetic data generation; deliver validated methodology and training recipes for pipeline operationalization.
  • Interface with the storage domain expert to validate physics constraints before deployment.
  • Produce validated research prototypes with complete technical documentation to team-handoff standard.
  • Participate in design reviews as the research methodology authority.

Desired Qualifications

  • Experience with diffusion models, including DDPM and conditional diffusion, for physics-constrained synthetic data generation.
  • Experience with graph neural networks for materials property prediction and failure propagation modeling.
  • Experience with neural ordinary differential equations for dynamic systems and degradation trajectory modeling.
  • Experience fine-tuning foundation models for domain adaptation in scientific tasks.
  • Experience with reinforcement learning for scientific discovery and exploration strategies in experimental search spaces.
  • Top-venue publication in NeurIPS, ICML, ICLR, or Nature Machine Intelligence.
  • Background in materials science, semiconductors, or precision product development.

About the Company

Western Digital

Makes hard drives for cloud and AI data centers

Western Digital, which goes by WD, designs and makes hard disk drives, mostly the high-capacity models that cloud and AI data centers use to store huge amounts of data cheaply. In 2013, its HGST unit shipped the first helium-filled hard drives, which fit more disks into each drive and use less power. Its drives store data on stacks of spinning magnetic disks, and the lineup runs from Ultrastar data center drives to WD Red and WD Purple drives for home servers and security cameras. WD makes its money selling these drives to cloud companies, PC makers, and retail shoppers. Western Digital was founded in 1970 and is based in San Jose, California, and in 2025 it spun off its flash memory business as Sandisk.
