Experto En Física – Ai Content Specialist$35-55/hr Remote Freelance StemWe're looking for physics experts in Mexico City and across Mexico to help train and evaluate cutting-edge AI models. Your deep understanding of physics will directly shape how AI reasons through complex problems — from undergraduate mechanics to graduate-level electromagnetism and beyond. This is a fully remote, flexible contract role where your subject matter expertise is the most valuable thing you bring. No AI background required.
Organization: Alignerr
Type: Hourly Contract
Location: Remote (Mexico City, Mexico)
Commitment: 10–40 hours/week Design challenging, rigorous physics problems across domains such as mechanics, electromagnetism, thermodynamics, and quantum physics. Develop clear, step-by-step solutions that demonstrate precise reasoning and logical structure. Evaluate AI-generated responses for scientific accuracy, depth of reasoning, and quality of explanation. Collaborate with researchers to develop and refine benchmarks spanning undergraduate to Masters-level physics. Provide structured, actionable feedback that helps AI systems reason more like expert physicists. Currently pursuing or have completed a Masters degree in Physics, Applied Physics, or a closely related field — from UNAM, IPN, CINVESTAV, or equivalent institutions Strong physics reasoning and problem-solving skills across multiple advanced domains Able to communicate complex concepts clearly and concisely in written English Detail-oriented with a systematic approach to quality and accuracy Self-motivated and comfortable working independently and asynchronously No prior AI experience required Experience with data annotation, evaluation systems, or academic content creation Familiarity with AI or machine learning concepts Background in research, tutoring, or technical writing Work directly on frontier AI projects in partnership with leading AI research labs. Fully remote and async — work on your own schedule from anywhere. Freelance perks: high autonomy, variety, and global collaboration. Contribute to meaningful work that advances the state of AI in STEM.Potential for ongoing contract renewals and expanded project scope.
