Job Overview by Ladders

Qualifications

  • Deep expertise in physics, particularly in fluid dynamics and thermodynamics, usually at a PhD level or equivalent research experience.
  • Familiarity with numerical simulation techniques, such as CFD, and understanding their trade-offs.
  • Interest in the integration of machine learning with physical modeling.
  • Strong collaborative skills to work effectively with ML researchers and translate physics principles into technical terms.
  • Evidence-driven mindset for assessing model quality and coherence.

Responsibilities

  • Assess the model's consistency with conservation laws and physical constraints using physical principles.
  • Develop evaluations to ensure the model's behavior is physically coherent, not merely statistically accurate.
  • Provide advisory input on the physics of modeled systems, including fluid dynamics and thermodynamics.
  • Investigate the generalizability of the LPM across different physical domains and identify breakdowns.
  • Collaborate with various teams to link physical understanding to research direction.
Full Job Description
Responsibilities
  • Bring physical principles to bear on the model - assessing consistency with conservation laws and physical constraints, and where physics-informed inductive biases help or hinder
  • Develop evaluations that test whether the model's behavior is physically coherent, not just statistically accurate
  • Advise on the physics of the systems we model, from fluid dynamics to thermodynamics, and their numerical treatment
  • Investigate where the LPM generalizes across physical domains and where it breaks down
  • Partner with model, evaluation, and interpretability teams to connect physical understanding to research direction


What we're looking for

We value a relentless approach to problem-solving, rapid execution, and the ability to quickly learn in unfamiliar domains.
  • Deep expertise in physics - fluid dynamics, thermodynamics, computational physics, or a closely related field (typically a PhD or equivalent research experience)
  • Familiarity with numerical simulation of physical systems (e.g. CFD) and its trade-offs
  • Interest in where machine learning and physical modeling meet
  • Ability to collaborate closely with ML researchers and translate physical principles into technical requirements
  • A rigorous, evidence-driven approach to evaluating model quality
