Especialista em Física – AI Content Specialist

Physics Subject Matter Expert (AI Training)

About the Role

We're looking for physics experts in São Paulo and across Brazil 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 (São Paulo, Brazil)
• Commitment: 10–40 hours/week

What You'll Do

• 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

Who You Are

• Currently pursuing or have completed a Masters degree in Physics, Applied Physics, or a closely related field — from USP, UNICAMP, UFRJ, 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

Nice to Have

• Experience with data annotation, evaluation systems, or academic content creation
• Familiarity with AI or machine learning concepts
• Background in research, tutoring, or technical writing

Why Join Us

• 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
