2026/2027 PhD Residency - Scientific ML (SciML) and Multiscale Physics (Early Stage Project)

InternshipMountain View, CA

How you will make 10x impact:

  • Combining fluid dynamics and machine learning to solve some of the most important problems in materials discovery and manufacturing
  • Working at the absolute forefront of simulation + experimentation, replacing computationally heavy, brute-force forward solvers with lean, physics-informed architectures

This project is focused on building advanced simulations and models along with custom equipment and processes to accelerate materials discovery and other critical manufacturing challenges.

  • Location: X's headquarters in Mountain View, CA
  • Start Date(s): Year-round rolling basis
  • Duration: a flexible 6 mo. to 1 year program based on project team needs and your availability

Throughout your AI Residency you can expect:

  • To be embedded into one of our confidential or public X projects
  • To get paid competitively and receive benefits
  • To be a part of a lively community of AI and ML Residents
  • To attend tech-talks with AI leaders from across X

What you should have:

  • Must be actively enrolled in a PhD program
  • First-principles understanding of multiscale physics from continuous fluid dynamics to discrete particle modeling
  • Proven expertise in Scientific Machine Learning (SciML), specifically the ability to parameterize unresolved or complex physics (e.g., phase coupling, closure terms) into autodifferentiable physics solvers and implement, optimize, and scale relevant SciML frameworks
  • Practical familiarity with laboratory environments, physical instrumentation, or a strong, demonstrated inclination to tinker and build

It’d be great if you also had these:

  • Direct experience with PINNs, Neural Operators, and traditional ML
  • Proficiency in high-performance simulation tools (e.g., COMSOL, OpenFOAM)
  • Track record of applying machine learning to complex physical systems (e.g., turbulence, multiphase flow, or inverse design)

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans' Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.
