Responsibilities:
  • Set technical direction for large-scale data processing solutions using Scala, Spark, SQL, and modern data platforms across the attribution ecosystem.
  • Architect and operate trusted pipelines handling advertiser, customer, and measurement datasets within secure cloud environments and approved data-sharing ecosystems.
  • Collaborate with Product, Data Science, Security, Privacy, and Platform Engineering to deliver privacy-preserving attribution, measurement, forecasting, and analytics solutions.
  • Define architecture for batch and streaming workflows, including orchestration frameworks and cloud-native services.
  • Implement data classification, access controls, and privacy-preserving processing techniques to meet security and compliance requirements.
  • Establish architectural direction for clean-room and trusted data-sharing environments with approved aggregated or privacy-protected outputs.
  • Build observability, monitoring, and operational tooling to ensure reliability, performance, and compliance.
  • Troubleshoot complex platform, performance, and pipeline issues across distributed systems.
  • Drive architecture decisions, engineering best practices, and operational excellence across attribution and adjacent data products.
  • Mentor and grow senior and lead engineers and provide technical leadership across teams and product areas.
  • Design and implement pipelines within trusted environments across AWS, Google Cloud Platform, Azure, and on-premises infrastructure.
  • Implement access controls, data classification policies, lineage tracking, and governance controls for sensitive data.
  • Define and maintain data handling standards with Security, Privacy, and Compliance stakeholders.
  • Enforce privacy-preserving principles to ensure only aggregated, anonymized, tokenized, or otherwise approved outputs leave trusted environments.
  • Build monitoring and alerting to detect anomalous movement, policy violations, and potential leakage.
  • Apply privacy-preserving computation techniques, including aggregation-before-export, pseudonymization and tokenization, differential privacy concepts, and privacy-aware reporting.
  • Implement encryption, key management, and secure data handling using cloud-native services.
  • Document trust boundaries, data contracts, lineage, and permitted data movement between zones.
  • Support audits, compliance requirements, governance reviews, and secure data-sharing initiatives.
  • Participate in architecture and design reviews for new data products to incorporate governance, privacy, lineage, and trust-boundary requirements.
  • Contribute to engineering standards and best practices for secure data processing and privacy-preserving analytics.

Experience Requirements:
  • 10+ years of data engineering with deep Scala and extensive Apache Spark for large-scale processing on AWS and/or Google Cloud Platform.
  • Strong Python for pipelines, tooling, automation, and infrastructure modules.
  • Advanced SQL across relational, cloud warehouses, and lakehouse platforms with TB-scale datasets.
  • Designing, building, and maintaining batch and streaming pipelines.
  • Strong understanding of warehousing, dimensional modeling, data quality, partitioning, and performance optimization.
  • Experience with lakehouse architectures such as Databricks, Delta Lake, or equivalent.
  • Operating distributed data platforms at scale.
  • Workflow orchestration with Airflow, Databricks Workflows, AWS Step Functions, or equivalent.
  • Source control and testing practices including unit, integration, and automation.
  • Cloud-native development on AWS and/or Google Cloud Platform.
  • Strong engineering practices including CI/CD, code reviews, observability, and production support.
  • Proven ability to set technical direction across teams and mentor senior engineers.
  • Trusted environment execution: clean rooms and secure data-sharing platforms, handling PII and regulated data, fine-grained access controls, and policy-based enforcement.
  • Working knowledge of data classification frameworks including PII, PCI, regulated data, and sensitivity-tier models.
  • Familiarity with tokenization, pseudonymization, aggregation-before-export, and differential privacy concepts.
  • Experience with clean-room, measurement, attribution, audience analytics, partner data-sharing, or privacy-preserving reporting.
  • Lineage and governance tooling such as Unity Catalog, AWS Glue Data Catalog, Apache Atlas, or OpenLineage.
  • Understanding of trust boundaries, secure sharing patterns, and zero-trust data architecture principles.
  • Documenting data contracts, flows, lineage, and permitted movement between security zones and domains.
  • Encryption, key management, and secure handling using cloud-native security services.
  • Designing observability and alerting controls to detect anomalous movement, policy violations, and potential leakage.
  • Experience in environments where only aggregated, anonymized, tokenized, or privacy-protected outputs may exit trusted processing environments.
  • Strong understanding of cloud-native security and governance.
  • Good to have: Databricks ecosystem, AWS Clean Rooms, advertising measurement and attribution platforms, collaboration with Security and Compliance in regulated settings, ELK, Grafana, OpenTelemetry, Docker, Kubernetes, and security architecture or threat modeling.
  • Strong written and verbal English communication skills.
  • Good understanding of Agile and SCRUM within cross-functional teams.
