As our Digital Advertising Data Analyst, you won't just be moving data—you'll be defending our revenue and driving our growth. You will bridge the gap between complex datasets and high-pressure business decisions. Whether you are uncovering a campaign's "hidden" success to secure a contract renewal or identifying sophisticated ad fraud to protect a client's budget, your insights will be the backbone of our commercial strategy.

• →Performance Optimization: Analyze real-time campaign data to provide actionable "pivot" suggestions that directly improve client KPIs.
• →Sales Enablement: Build data-backed narratives and "evidence packages" that empower our sales team to win renewals and upsells.
• →Fraud Defense: Develop and maintain fraud detection reports to proactively address client concerns and ensure high-quality traffic.
• →Stakeholder Communication: Present findings clearly to management and clients, often in high-pressure situations where data must be the "voice of reason."

To succeed in this role, you must be a power user of our primary stack:

• SQL: Expert level. Ability to write complex, performant queries across large, nested datasets.
• Python: Proficient in data manipulation (Pandas/NumPy) and automating repetitive reporting tasks.
• Tableau: Ability to build intuitive, client-facing dashboards that tell a story at a glance.
• Google Sheets: Advanced capabilities for quick-turnaround tactical analysis.

 [Preferred qualifications]

• Working experiences in digital advertising industries.

• Battle-Tested: You have thick skin. You can stay calm and objective when presenting data to stressed stakeholders or skeptical clients.
• Business Intuition: You understand that a 0.05% change in CTR matters to the bottom line. You don't just report numbers; you explain what they mean for the client's wallet.
• Analytical Curiosity: You don't wait to be told what to look for. You see a dip in performance and hunt for the "why" before anyone asks.

This isn't a "back-office" job. You will have a seat at the table during major contract negotiations and play a pivotal role in the company's financial health.
