• Strong SQL proficiency (complex joins, window functions, query optimization on massive databases).
• Practical experience working in Python or R for data wrangling, exploratory statistical analysis, and visualization.
• Solid understanding of foundational statistics (distributions, correlation vs. causation, hypothesis testing).
• Curious, proactive mindset with strong problem-solving skills and attention to data edge cases.
• Familiarity with Connected TV (CTV), digital advertising, or auction systems is a distinct advantage, but not strictly required.
• Must be legally authorized to work in the United States without current or future sponsorship needs.
