We are seeking an experienced Senior Data Engineer to help build the next generation of our identity graph and data platform. This role is focused on designing, developing, and optimizing large-scale data pipelines and systems that ingest, process, and unify complex datasets from diverse sources (web, mobile, AdTech, government, and proprietary data).

This is a highly hands-on, technical role for someone who can quickly understand existing systems, operate independently, and deliver high-quality solutions at scale. The ideal candidate is deeply analytical, detail-oriented, and experienced with building performant data pipelines and systems handling billions of records.

• Design, build, and optimize scalable data pipelines and ETL/ELT workflows for large, complex datasets.
• Design and implement foundational data architecture supporting identity resolution and ID graph systems.
• Develop and enhance systems supporting identity resolution and ID graph construction (data ingestion, normalization, matching, and deduplication).
• Process and unify multi-source datasets (cookies, device IDs, behavioral data, third-party and proprietary data).
• Write efficient, testable, and maintainable code using Python and SQL for large-scale data processing.
• Optimize data models, queries, and storage strategies for performance, scalability, and cost efficiency.
• Build and maintain data validation, monitoring, and alerting systems to ensure data quality and reliability.
• Troubleshoot, debug, and improve existing data pipelines and infrastructure.
• Take ownership of complex data problems end-to-end, from initial design through production deployment.
• Contribute to key technical decisions related to data architecture, scalability, and system design.
• Collaborate with data, platform, DevOps, and product teams to deliver scalable, production-ready solutions.
• Translate business and product requirements into practical, performant data solutions.
• Document data pipelines, systems, and workflows clearly.
• Continuously improve system performance, data quality, and pipeline resilience.
• Contribute to building new capabilities that improve how customers understand and leverage data insights.

• 5–8+ years of hands-on experience in data engineering or large-scale data processing.
• Proven experience building and maintaining production-grade data pipelines and distributed systems.
• Experience contributing to the architecture and delivery of large-scale data platforms or mission-critical data systems.
• Strong expertise in:
  • SQL and relational databases (Postgres, BigQuery, Redshift, etc.)
  • Python for data processing and analysis
  • Experience with Google Cloud Platform (BigQuery, Dataflow, Pub/Sub, Cloud Storage, Cloud Functions) and/or AWS (S3, Redshift, EMR, RDS).
  • Experience working with large-scale datasets (hundreds of millions to billions of records).
  • Strong understanding of data modeling, partitioning, indexing, and query optimization.
  • Experience with distributed data processing and parallelization techniques.
  • Experience moving large volumes of data across systems and architectures.
  • Familiarity with CI/CD, containerization, and orchestration tools (Docker, Kubernetes, GitHub Actions, etc.).
  • Strong debugging and troubleshooting skills in complex data environments.
  • Experience with version control (Git) and Agile tools (Jira, Confluence, etc.).
  • Highly analytical with strong attention to detail and a data-driven mindset.
  • Ability to hit the ground running, quickly understand systems, and deliver independently.
  • Comfortable working in a remote, fast-paced, and collaborative environment.
  • Strong ability to contribute to system design and deliver implementations independently.
