Team Overview

The Data Solution pod is the technical unit within Innovation responsible for leveraging Teads' publisher integrations and network scale to provide targeting solutions and measurable business outcomes. We build the infrastructure that unifies fragmented signals from the "Open Internet" into actionable data about the customer journey for our SSPs and internal Buying Engines.

Key Responsibilities

Identity

• Manage the identity graph at scale, interpreting data across the 30% deterministic / 30% interpreted / 40% probabilistic split.
• Evolve service-identity (Scala, C*) and oversee the production delivery of identity signals to the rest of the stack.
• Maintain privacy libraries and services to adapt signal ingestion to regional laws (GDPR, US, Asia) and browser restrictions.
• Leverage BigQuery/DBT and Python/Airflow for signal analysis and exploratory technical tooling.

Measurement

• Build the full-stack infrastructure for premium metrics (Attention, Brand Lift, Sales Uplift).
• Develop ETLs and integrate Data Science logic to transform raw signals into actionable reporting.
• Design and implement internal/external APIs to facilitate third-party feedback loops with measurement providers.
• Create high-performance dashboards and tools in TAM to show delivered outcomes.

Targeting

• Develop/improve systems for user segmentation and cookieless data ingestion, ensuring multi-screen consistency.
• Build planning engines using BigQuery or other SQL technology to estimate reach, frequency, and ad opportunities volume.
• Deep integration with delivery services: as for example service-dmp (segment management) or lib-tbl (real-time rule resolution) and their future implementation in multivac and in the bidder.
• Ensure targeting rules are correctly propagated to internal Backends and external DSP/SSP integrations.
