This position is built for people who value correctness over speed. The labels you create become the foundation for AI systems that support thousands of students daily. Precise behavioral tagging strengthens the model; inconsistent labeling teaches it incorrect patterns.
LearnWith.AI develops AI-driven learning tools grounded in learning science, data analytics, and expert knowledge. Your role is to convert unstructured student session recordings into reliable, rubric-aligned annotations the team depends on. You will review recorded sessions, pinpoint critical behavioral moments, and apply defined classification rules to capture what occurred and its timing. You will also validate LLM-generated pre-annotations, correct inaccuracies, and flag ambiguous cases to help engineers refine the pipeline.
This is not freelance, ad-hoc labeling work. It involves a consistent workflow within one product area, supported by regular feedback, alignment with gold-standard benchmarks, and advancement tied to precision and reliability. If you thrive on explicit standards, trackable quality metrics, and contributions that shape model outcomes, this opportunity is for you.
Your primary function is to transform student session videos into labeled datasets achieving ≥95% accuracy with precise timestamps, enabling the team to reliably measure model improvements or regressions.
