Data Scientist

• Build and evaluate ML approaches for company/entity matching
• Develop embedding and LLM-based matching approaches
• Develop scoring and ranking methodologies to identify true matches and distinguish them from duplicates, lookalikes, and unrelated entities
• Work with messy data, including names, aliases, domains, websites, firmographic attributes, multilingual records, and data hierarchies
• Define benchmark datasets, metrics, baselines, and error-analysis processes
• Design and execute experiments to validate hypotheses
• Compare LLM-assisted approaches against lower-cost alternatives
• Analyze model behavior, edge cases, and trade-offs
• Consider inference economics and scalability from the beginning
• Communicate experimental findings and recommendations to engineering and business stakeholders
• Independently establish experimental pipelines and research approaches
• Clearly document both successful and unsuccessful experiments
