AI Engineer Internship – LLM Data

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.

Run experiments to understand how different data sources and processing strategies impact model performance.

Support model inference, evaluation, and training experiments when needed to validate data quality.

Research new datasets, data processing techniques, and LLM data methodologies.

Collaborate closely with researchers and engineers on fast-moving foundation model projects.

Currently pursuing a Bachelor’s, Master’s, or PhD degree in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or a related technical field.

Strong programming skills in Python.

Good understanding of machine learning, deep learning, NLP, or large language models.

Hands-on experience with LLMs through research, coursework, projects, internships, or open-source work.

Comfortable working with datasets and performing data processing and analysis.

Strong problem-solving skills and willingness to learn new technologies quickly.

Ability to work independently and collaborate effectively in a fast-paced research environment.

Experience with PyTorch, Hugging Face, vLLM, or similar ML/LLM frameworks.

Experience with LLM data synthesis, fine-tuning, model evaluation, or prompt-based generation.

Familiarity with LLM training pipelines, including pre-training, supervised fine-tuning, or other post-training methods.

Experience working with large-scale datasets or distributed data processing.

Relevant research, open-source contributions, competitions, or personal projects in LLMs or generative AI.
