[Hiring] PhD Physicist, AI Expert @Weekday AI

Role Description

We are seeking highly experienced PhD Physicists and senior research professionals to contribute their scientific expertise to the development, evaluation, and advancement of next-generation Artificial Intelligence (AI) models.

In this role, you will work alongside leading AI researchers to assess how advanced AI models understand and reason about complex physics concepts and real-world scientific problems. You will leverage your research experience and specialized domain knowledge to evaluate physics-related tasks, develop rigorous problem specifications, create reference solutions, and design challenging benchmarks that measure the scientific reasoning capabilities of AI systems.

Key Responsibilities

• Expert Evaluation: 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.
• Problem Design: Develop precise, research-level physics problem statements and detailed specifications that reflect real-world scientific challenges.
• Reference Solutions: Create rigorous reference solutions, demonstrating correct scientific reasoning, mathematical derivations, and appropriate methodologies.
• Benchmark Development: Design complex physics problems and evaluation datasets within your area of specialization to assess and improve AI model performance.
• Scientific Assessment: Evaluate AI-generated reasoning and distinguish scientifically valid arguments from responses that appear convincing but contain conceptual or mathematical errors.
• Research Collaboration: Work with AI researchers and subject matter experts across related disciplines to establish clear evaluation standards and measurable quality criteria.
• Feedback & Calibration: Translate specialized scientific knowledge and expert judgment into structured feedback and evaluation frameworks that improve AI reasoning capabilities.

Qualifications

• PhD in Physics, Astrophysics, Applied Physics, or a closely related discipline.
• Senior-level academic or research experience, such as:
  • Faculty appointment at a recognized university.
  • Principal Investigator (PI).
  • Staff Scientist or Senior Scientist.
  • Equivalent senior research position at a university, national laboratory, or established research organization.
• Deep specialization in at least one of the following physics domains:
  • Condensed Matter Physics.
  • High-Energy Physics / Particle Physics.
  • Astrophysics and Cosmology.
  • Atomic, Molecular, and Optical (AMO) Physics.
  • Quantum Physics.
  • Statistical Physics.
  • Computational Physics.
  • Applied Physics.
• Strong peer-reviewed research publication record.
• Recognition through competitive research fellowships, academic awards, grants, or other scientific achievements is an added advantage.
• 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 with the ability to develop precise problem statements and structured technical feedback.
• Must be currently based in the United States.

Requirements

• Engagement will be on an independent contractor basis.
• The position is fully remote and offers flexibility to complete assignments according to your own schedule and project requirements.
• Project timelines may be extended, shortened, or concluded early depending on business requirements and individual performance.
• The engagement will not require access to confidential or proprietary information belonging to any current or former employer, client, university, or research institution.
• Payments will be processed weekly through Stripe or Wise based on services rendered.
• H-1B and STEM OPT visa holders cannot be accommodated for this opportunity.
