The Role 

We’re looking for a Senior Data Engineer to design, build, and operate the data processing layer that powers Zeta’s AdTech platform. This is a hands-on role focused on streaming + batch pipelines, producing trusted, reusable aggregates that serve multiple downstream consumers including prediction/ML features, agentic workflows, BI reporting, and measurement. 

What You’ll Do 

• Build streaming pipelines: Ingest and process high-volume event data using Kafka/Kinesis, handling schema evolution, event-time processing, late data, and deduplication. 

• Create canonical aggregates: Produce durable, well-defined rollups (campaign, audience, creative, inventory, pacing/spend, conversions, measurement) with consistent semantics and SLAs. 

• Enable prediction & agents: Deliver feature-ready datasets and near-real-time signals to support model training/scoring, retrieval, and agent decision loops. 

• Support BI & reporting: Publish governed datasets to analytics systems and warehouses for dashboards, ad-hoc queries, and operational reporting. 

• Measurement-grade reliability: Implement reconciliation, backfills, audit trails, and quality checks to ensure correctness for reporting and measurement. 

• Optimize performance & cost: Tune pipeline throughput/latency, storage formats, partitioning, and compute spend across streaming and batch workloads. 

• Operational excellence & observability: Instrument pipelines with metrics/logs/traces, define SLIs/SLOs, and drive fast detection and root-cause analysis. 

• Collaborate cross-functionally: Partner with Backend, ML/DS, Analytics, and Platform/SRE to define contracts, schemas, and robust data products. 

Required Qualifications 

• 7+ years building and operating production-grade data pipelines. 

• Strong experience with streaming systems: Kafka (preferred) or AWS Kinesis, and event-driven architectures. 

• Hands-on experience with processing frameworks such as Flink, Spark (Structured Streaming), Beam, or equivalent. 

• Proficiency in Python and/or Java/Scala (Go is a plus). 

• Strong SQL skills and experience with data modeling for analytics and aggregates. 

• Strong experience with AWS and cloud-native data patterns (S3 + compute/orchestration services). 

• Experience with data warehouses / OLAP (e.g., Snowflake/Redshift/BigQuery) and/or real-time analytics stores (e.g., ClickHouse/Druid). 

• Familiarity with SQL + NoSQL ecosystems (e.g., Postgres/MySQL + DynamoDB/Cassandra/Redis) for serving/lookup patterns. 

• Experience with orchestration and CI/CD for data pipelines (Airflow/Argo/Step Functions or equivalents). 

• Clear communicator and collaborator; able to explain data systems and trade-offs to mixed audiences. 

Preferred Qualifications 

• Programmatic advertising domain knowledge: event pipelines for impressions/clicks/conversions, attribution/measurement, pacing/budget signals. 

• Experience building feature stores or ensuring online/offline parity for ML features. 

• Lakehouse experience (Delta/Iceberg/Hudi), incremental processing, and backfill strategies at scale. 

• Strong data governance practices: lineage, access controls, PII handling, privacy-by-design. 

• Experience operating at “extreme scale” (billions of events/day) and optimizing cost/performance. 

BENEFITS & PERKS

• Excellent medical, dental, and vision coverage
