What You'll Do

Daily Performance Monitoring

Track and report on key ad performance metrics (revenue, fill rate, CPM, CTR, ROAS, etc.) on a daily basis, proactively identifying anomalies, trends, and areas of concern.

Root Cause Analysis

Investigate the drivers behind revenue fluctuations or performance declines — e.g., diagnosing why ad revenue dropped on a given day by examining inventory levels, demand shifts, bid price changes, or seasonality effects.

Ad Inventory & Fill Rate Tracking

Monitor ad inventory availability and fill rates, flagging imbalances between supply and demand and escalating issues to senior stakeholders.

Performance Reporting

Build and maintain dashboards and recurring reports that give clear visibility into marketplace health, ad placement performance, and demand trends.

Placement & Targeting Analysis

Analyze ad placement performance across different surfaces and audience segments, identifying opportunities to improve visibility, relevance, and results.

Cross-Functional Support

Collaborate with product, engineering, data science, and sales teams by providing data-backed insights that inform marketplace decisions and ongoing optimizations.

Ad vs. Organic Analysis

Support the comparison of ad performance against organic performance benchmarks to identify growth and optimization opportunities.

What You'll Need

Experience

1–2 years of experience in digital advertising, ad operations, e-commerce analytics, or a related field.

Analytical Skills

Strong ability to work with data to identify trends, diagnose issues, and communicate findings clearly. Comfort with ambiguity and a curiosity-driven approach to problem-solving.

Technical Skills

Familiarity with Excel/Google Sheets is a must. Basic knowledge of ad platforms or ad serving concepts is a plus.

Attention to Detail

A sharp eye for spotting anomalies in data and a structured approach to root cause analysis.

Communication

Ability to translate data findings into clear, concise summaries for both technical and non-technical audiences.

Education

Bachelor's degree in Business, Economics, Statistics, Engineering, or a related quantitative field.

Curiosity about Ad Tech

Familiarity with core concepts such as CPM, CPC, auction mechanics, bid pricing, or programmatic advertising is a plus — but a strong willingness to learn is equally valued.
