Senior Data Scientist

• Write code (Python, R, SQL, Java, etc.) to obtain, clean, manipulate, and analyze data.
• Retrieve, synthesize, and present critical data in a format that is immediately useful to answering specific questions or improving system performance.
• Analyze and interpret historical data to identify trends and support optimal decision making.
• Drive the development of machine learning and statistical models to solve specific business problems.
• Leverage AI/LLM frameworks to develop internal and external solutions.
• Capitalize on opportunities for improving workflows to increase data quality, accuracy, and timeliness.
• Lead experiments to test hypotheses and measure the effectiveness of solutions.
• Formalize assumptions about how our systems should work, create statistical definitions of outliers, and develop methods to systematically identify outliers. Determine why such examples are outliers and if action is needed.
• Partner with engineering teams to help implement end-to-end pipelines.
• Champion collaboration across teams to deliver enhancements, features, and time-sensitive projects.
• Deliver reports or presentations to share insights to audiences of varying levels of technical sophistication.
• Maintain a portfolio of self-directed projects that are aligned with business goals.
