About this Role
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
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.

Frequently Asked Questions
What is the assessment actually like?
Notoriously strict. Alignerr uses TestGorilla for role-specific timed tests — a blank coding environment for engineers, rigorous grammar and fact-checking for writers. There is almost no hand-holding. The critical catch: this is essentially a one-shot process. Fail or abandon the assessment, and you are typically locked out of that role permanently with no option to retake.
How quickly can I start earning after I pass?
Not immediately. Even after passing the assessment and completing identity verification (via Persona) and billing setup (via Deel), you may sit in a waiting pool for weeks or months. You only start earning when a project matching your specific skills launches and you are officially assigned. Do not plan around Alignerr income until you are actively on a project.
Is there a community?
Yes — and it is one of Alignerr's genuine strengths. Once assigned to a project, you are added to Slack channels where you can ask questions, get rubric clarifications from admins, and talk to other AI trainers. This is rare in AI training and makes a real difference when guidelines are ambiguous or change mid-project.
What does the work actually look like?
It is practical, hands-on data work. You might be recording short videos, categorizing images, rating text responses, or analyzing data. The tasks are designed to be short and distinct—typically 5-60 minutes per task.
How flexible is the schedule?
Extremely. This is true "log in and work" flexibility. You can usually work for 20 minutes or 4 hours depending on your availability. There are rarely minimum hour requirements, making it ideal for side income.
Is there an interview?
Usually, no. Hiring for these roles is almost entirely based on passing an automated assessment or "qualification" task. If you pass the test, you get access to the work.
What is the barrier to entry?
Alignerr is known for difficult technical assessments. You must pass a timed test in your specific domain (e.g., Python, Physics, or Language) before you are eligible for any paid projects.
