Collaborate with linguists, data operations teams, and ML engineers on data collection, curation, annotation, and localization efforts for model training and fine-tuning
Contribute to the development and maintenance of annotation schemas and guidelines for LLM training data (e.g., instruction-tuning, preference labeling, RLHF)
Evaluate and quality-check datasets used for pre-training, fine-tuning, and alignment of language models
Support the development of programmatic methods for generating synthetic annotated data at scale
Assist in model evaluation efforts including prompt-based testing, red-teaming, and linguistic error analysis
