You will dig into massive volumes of streaming and programmatic bidstream data, diagnosing performance bottlenecks, testing buying strategies, and providing actionable recommendations to maximize ROAS and campaign scale for our advertising partners.

Responsibilities

• CTV Strategy Optimization: Analyze campaign delivery, bid shading, floor pricing, and fill rates across streaming platforms and SSPs to optimize buying strategies.
• Performance Deep-Dives: Run exploratory analyses and statistical deep-dives to diagnose fluctuations in campaign performance, inventory quality, and ad spend efficiency.
• Data-Driven Insights: Translate complex auction telemetry and viewing signals into clear, actionable recommendations for our commercial, programmatic operations, and product teams.
• Metric Definition & Reporting: Build reliable, repeatable analytical workflows and ad-hoc statistical summaries to evaluate cross-device reach and frequency.

• 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.
