PhD Physicist, AI Expert (Remote, US)
About The Position
This role is for one of the client's projects. The position seeks experienced PhD physicists and senior research professionals to contribute scientific expertise to the development, evaluation, and advancement of AI models. Working alongside AI researchers, the physicist will assess how models understand and reason about complex physics concepts and scientific problems. The work includes evaluating physics-related tasks, developing rigorous problem specifications, creating reference solutions, and designing challenging benchmarks that measure scientific reasoning. The ideal candidate is an established physicist with a strong academic or research background, deep specialization in at least one physics area, and hands-on experience with large language models. The engagement is as an independent contractor, fully remote within the United States, with a flexible schedule. Project timelines may change according to business needs and individual performance. The work does not require access to confidential or proprietary information belonging to a current or former employer, client, university, or research institution. Payments are made weekly through Stripe or Wise for services rendered. H-1B and STEM OPT visa holders cannot be accommodated.
Requirements
- PhD in Physics, Astrophysics, Applied Physics, or a closely related discipline.
- Senior-level academic or research experience, such as a faculty appointment at a recognized university, Principal Investigator, Staff Scientist, Senior Scientist, or equivalent senior research position at a university, national laboratory, or established research organization.
- Deep specialization in at least one of the following: Condensed Matter Physics; High-Energy Physics / Particle Physics; Astrophysics and Cosmology; Atomic, Molecular, and Optical (AMO) Physics; Quantum Physics; Statistical Physics; Computational Physics; or Applied Physics.
- Strong peer-reviewed research publication record.
- Hands-on experience using Large Language Models (LLMs) and AI tools in research or scientific workflows.
- Ability to critically evaluate AI-generated scientific arguments, mathematical derivations, and technical explanations.
- Excellent written communication skills and ability to develop precise problem statements and structured technical feedback.
- Must currently be based in the United States.
- H-1B and STEM OPT visa holders are not eligible for this opportunity.
Nice To Haves
- Recognition through competitive research fellowships, academic awards, grants, or other scientific achievements.
Responsibilities
- Review physics-related tasks and AI-generated outputs for scientific accuracy, logical consistency, and mathematical rigor.
- Identify flawed derivations, unjustified assumptions, inappropriate approximations, dimensional inconsistencies, and errors in boundary or limiting cases.
- Develop precise, research-level physics problem statements and specifications reflecting real-world scientific challenges.
- Create rigorous reference solutions demonstrating correct scientific reasoning, mathematical derivations, and appropriate methodologies.
- Design complex physics problems and evaluation datasets in the candidate's area of specialization to assess and improve AI model performance.
- Evaluate AI-generated reasoning and distinguish scientifically valid arguments from responses containing conceptual or mathematical errors.
- Collaborate with AI researchers and subject matter experts across related disciplines to establish evaluation standards and measurable quality criteria.
- Translate specialized scientific knowledge and expert judgment into structured feedback and evaluation frameworks to improve AI reasoning capabilities.
