AI Engineer Internship – LLM Data

As an AI Engineer Intern specializing in LLM data, you will work with our team to build and improve high-quality training data for foundation models across pre-training, mid-training, and post-training. You will gain hands-on experience with large-scale data processing, LLM-based data synthesis, data quality evaluation, and model experimentation.

• Build, curate, and improve datasets for LLM pre-training, mid-training, and post-training, including time-sensitive requests that may require fast turnaround.
• Develop and improve data processing workflows for data extraction, cleaning, filtering, deduplication, transformation, and quality control.
• Use LLMs to generate, refine, filter, and evaluate synthetic data.
• Analyze data quality and identify issues such as duplication, low-quality samples, distribution gaps, and coverage limitations.
