• Member of a team that has trained a large language model from scratch (10B+ parameters, 500B+ tokens).
• Publications in deep learning theory or at conferences such as ACL, NAACL, EMNLP, NeurIPS, ICML, or ICLR.
• PhD focused on topics related to guiding LLMs with further tasks (Supervised Finetuning, Instruction-Tuning, Dialogue-Finetuning, Parameter Tuning).
• Demonstrated knowledge of principles of transfer learning, model adaptation, and model guidance.
• Experience deploying a fine-tuned large language model.
• Publications studying tokenization, data quality, dataset curation, or labeling.
• Contribution to a major open-source corpus or open-source libraries for data quality, dataset curation, or labeling.

Skills

• Innovative: Continually research and evaluate emerging technologies; stay current on published state-of-the-art methods and seek opportunities to apply them.
• Creative: Thrive on bringing definition to big, undefined problems; love asking questions and pushing hard to find answers.

• Technical: Comfortable with open-source languages and passionate about developing further; hands-on experience developing AI foundation models and solutions using open-source tools and cloud computing platforms.
• Deep understanding of the foundations of AI methodologies.
• Experience building large deep learning models (language, images, events, or graphs) and expertise in one or more of: training optimization, self-supervised learning, robustness, explainability, RLHF.
• Engineering mindset with a track record of delivering models at scale (training data and inference volumes).
• Experience delivering libraries, platform-level code, or solution-level code to existing products.
• Track record of high-quality ideas or improvements in machine learning, demonstrated by first-author publications or projects.
• Ability to own and pursue a research agenda, including choosing impactful problems and autonomously carrying out long-running projects.
