If accuracy matters more to you than speed, this position is a strong fit. The labels you create serve as training data for AI systems that support thousands of students daily. Precise behavioral tagging improves model intelligence. Inconsistent labeling teaches the model incorrect patterns.
LearnWith.AI develops AI-driven learning experiences through learning science, data analytics, and expert collaboration. This position converts raw student session recordings into highly accurate, rubric-based labels the team relies on. You will review recorded student sessions, pinpoint critical behavioral events, and apply rigorous classification rules to determine what occurred and when. You will also assess LLM-generated pre-annotations, correct errors, and document unusual cases to help engineers refine the system.
This is not freelance, ad-hoc annotation work. It involves a consistent workflow within one product area, featuring direct feedback channels, calibration with gold-standard examples, and advancement tied to accuracy and reliability. If you value transparent expectations, quantifiable quality standards, and contributions that directly shape model effectiveness, we should speak.
This position ensures that student session recordings are transformed into labeled datasets with ≥95% accuracy and precise timestamps, reliably indicating when model performance advances or declines.
Crossover's skill assessment process combines innovative AI power with decades of human research, to take the guesswork, human bias, and pointless filters out of recruiting high-performing teams.
