About the team
LLM Global Data is a team focused on producing international data for LLMs. For the training of large models, data is the lifeline of model quality — and the Global Data team is working closely with technical, product, and operations teams to ensure effective data production strategies and execution management. There’s a lot to do, and there’s substantial room for impact, similar to TikTok 5 years ago.
Responsibilities
1. Collaborate with technical teams to precisely define the data requirements necessary for aligning Large Language Models (LLMs) across global markets.
2. Develop methodologies for data acquisition and production, while also monitoring costs and assessing the effectiveness and efficiency of these processes. Ensure data quality is maintained at high standards and continually enhance processes based on both quantitative and qualitative feedback.
3. Evaluate the impact of data production tools on the effectiveness and quality of data production. Work closely with technical teams to enhance both the quality and effectiveness of these tools.
4. Proactively identify and mitigate potential biases and vulnerabilities in the data production process. This includes, but is not limited to, addressing human and system biases through the implementation of technical, product, and operational solutions.
Minimum Qualifications
Solid understanding of alignment and related approaches, such as Supervised Fine-Tuning (SFT), Reinforcement Learning from Human Feedback (RLHF), and others. Or solid experience in moderation, labeling, search quality, or data synthesis.
Minimum of three years of experience as a product manager or product strategist, including process design experience.
Preferred Qualifications
A strong interest in both LLMs and human behavior/experience/wellbeing. Must be an enthusiastic learner. This position is not suitable for individuals who find reading papers and books to be tedious.
