Responsibilities: Lead deep data investigations using SQL and internal tools to proactively identify, research, and explain ad quality trends and anomalies across brand safety, viewability, invalid traffic, non-human traffic, and inventory performance; present findings and recommendations to cross-functional partners and leaders. Own projects and collaborations with ad verification vendors and internal teams from initial requirements through testing, implementation, documentation, communication, and ongoing measurement, ensuring work remains aligned and actions are completed. Maintain and improve global quality controls, including exclusion lists, contextual category segments, marketplace packages, inventory audits, targeting channels, and other governed protections that help keep unsafe or low-quality supply out of client campaigns. Develop and maintain data ingestion and ETL pipelines, aggregations, SQL libraries, dashboards, automation tools, AI-enabled workflows, and repeatable process enhancements that improve efficiency across Media Quality and partner teams. Respond to critical issues involving digital advertising behavior, inventory, ad tags, verification data, or platform controls; assess impact, coordinate investigation, document evidence, and recommend practical corrective action.

Contribute to the Media Quality knowledgebase, quarterly statistics, training materials, process documentation, and evidence required for MRC accreditation, industry audits, and internal governance.

Identify operational processes that can be streamlined or automated, communicate roadmaps and progress to collaborators, and provide guidance to analysts and partners through subject-matter expertise and documented guidelines.

Qualifications: Advanced analytical, data mining, and problem-solving skills, with demonstrated ability to identify trends, anomalies, root causes, and operational risks in complex data sets. Strong working knowledge of SQL for investigation, reporting, monitoring, and data-quality workflows, plus experience developing or maintaining automation, visualizations, data pipelines, or reusable analytical tools. Demonstrated project ownership, with the ability to translate descriptive requirements into a plan, coordinate contributors, manage dependencies, document decisions, and deliver work from inception through completion with limited direction. Working knowledge of digital media quality, brand safety, viewability, invalid traffic, non-human traffic, ad verification, inventory quality, and the programmatic advertising ecosystem, including publishers, exchanges, DSPs, SSPs, and RTB standards. High attention to detail and the organizational rigor to maintain reliable documentation, repeatable processes, governed controls, training resources, and audit-ready evidence.
