Job description

This ad analytics company is doing something most can't: making sense of the chaos. They process billions of ad events daily and turn that noise into clear, actionable insights that help brands spend smarter and perform better. The clients include household names, and the data is genuinely fascinating. They're growing fast and need a Senior Data Scientist who can go beyond dashboards.

Responsibilities

• Build and deploy ML models that power ad performance insights — attribution, forecasting, audience clustering, and more.
• Work with massive datasets (billions of events) to extract patterns and build predictive systems.
• Collaborate with engineering to productionise models and integrate them into the platform.
• Partner with commercial teams to translate data insights into client value.
• Continuously experiment—test new approaches, validate hypotheses, and push the boundaries of what the data can tell us.

Qualifications

• Senior Data Scientist with 4+ years of hands‑on experience building and deploying ML models.
• Strong in Python and SQL — comfortable wrangling large datasets and writing production‑quality code.
• Experienced with cloud data platforms (BigQuery, Snowflake, Databricks, or similar).
• Solid statistical foundations and intuition for when to use what technique.
• Curious about the ad industry—or eager to learn how the money actually flows.
• A clear communicator who can explain complex findings to non‑technical stakeholders.
