Sr. Data Engineer

Build and run the data foundation behind AI-enabled marketing analytics, including ingestion, normalization, and reliability for sources across agencies, vendors, and platforms.

Responsibilities

• Design, build, and operate scalable data ingestion pipelines that pull marketing data from agencies, ad tech vendors, and internal sources on scheduled intervals
• Ingest data without requiring source teams to change their existing processes
• Define, evolve, and maintain input schemas and normalization logic to reconcile inconsistent granularity, formats, and terminology into a unified dataset
• Implement automated data quality validation, anomaly detection, and reconciliation to surface defects early and reduce manual auditing and cleanup
• Manage real-world data complexity, including delayed settlement, hierarchy mapping, and selection of planned versus finalized data
• Work with modeling and AI engineers to ensure the dataset supports downstream analytics, agent orchestration, and natural-language query
• Instrument pipelines for observability, freshness/SLA monitoring, and low-touch operations, so adding new sources is primarily configuration-driven
• Partner with data providers and stakeholders to onboard new feeds and improve timeliness, completeness, and accuracy
• Support a phased rollout starting with a core set of sources and expanding over time
