Physics Research Expert for AI Training

Nextmark; United States; On-site; USD 90,000 - 160,000; Full time

Job summary

Nextmark is seeking a PhD-level physicist to guide AI training with rigorous physics-based input. You’ll solve advanced problems, develop models in Python/SymPy/Jupyter, and provide publication-quality explanations.

The role requires independent work, excellent communication, and being based in the US/UK/Canada with eligibility to work in the US. Prior AI-training experience is valued but not required; domain knowledge matters most.

Qualifications

• PhD in physics with active, ongoing research in targeted subfields.
• 2–5 representative publications (last 5 years) with arXiv/DOI links.
• Proficiency in mathematical modeling, derivations, and proofs at publication standards.
• Proficient in LaTeX, Python, SymPy, and Jupyter; strong written and verbal communication.
• Must be based in the US, UK, or Canada with ability to work in the US if required.

Responsibilities

• Contribute deep domain expertise in physics subfield for AI training inputs.
• Formulate, solve, and document advanced mathematical physics problems.
• Develop and validate computational models, simulations, and analyses using Python/SymPy/Jupyter.
• Produce publication-quality explanations and derivations with clear reasoning.
• Communicate complex concepts clearly with project coordinators and AI team.
• Work independently to address novel research problems with minimal supervision.
• Review and improve problem solutions for accuracy and clarity in AI training.
