Role Mission

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.

Key Responsibilities

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."

About You

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.

The Ideal Candidate

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.

Why This Role?

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.
