Analyze large-scale legal datasets to extract insights and improve model performance.
•
Establish best practices for model evaluation, validation, and benchmarking.
•
Translate experimental results into clear product recommendations and business impact.
•
Collaborate with product, legal experts, and engineers to align solutions with user needs.
•
Mentor team members and provide technical leadership in data science and AI.
Requirements:
•
Education: Master’s degree or above in a quantitative or technical field (Statistics, Computer Science, Mathematics, Data Science, etc.).
•
Strong experience in machine learning, NLP, and LLM-based modeling.
•
Strong experience designing and running experiments, including model evaluation and iteration.
•
