We're looking for a Senior Data Engineer that is innovative, curious, and collaborative to help evolve the data platform that powers our sell-side media business. This role supports data-driven workflows and a broad range of media monetization use cases, with an emphasis on scalable, open data architectures. You’ll work on high-volume, revenue-critical media data while helping modernize how data is stored, processed, and served across the organization. This is a hands-on role for engineers who enjoy building, migrating, and improving platforms, not just maintaining them.

Ingest, integrate, transform, and model high-volume media and campaign data from multiple sources, delivering analytics-ready datasets that meet quality, accessibility, and business requirements. Develop lakehouse-style data models that balance flexibility, performance, and cost efficiency, enabling reporting, analytics, operational workflows, and downstream consumption. Build, optimize, and maintain ETL/ELT processes for both batch and near-real-time workloads, orchestrated with modern workflow tools (e.g., Airflow, Dagster). Collaborate with machine learning, client-facing, product, application, and analytics teams to understand requirements, support ML feature productionization, and enable self-service insights. Ensure data quality, lineage, observability, governance, and security, safeguarding cloud data assets and maintaining trust in revenue-critical systems. Contribute to platform evolution and migration efforts, including evaluating tools, improving workflows, and reducing architectural complexity. Continuously optimize pipelines, queries, and storage for performance, scalability, and cost efficiency. Mentor junior engineers and participate in technical design and architecture reviews. Detect, investigate, and resolve data anomalies to maintain pipeline reliability and data trustworthiness.
