Senior Data Engineer

Were looking for a Senior Data Engineer to design build and operate the data pipelines and aggregates that power Zetas AdTech platform. This is a hands-on individual contributor role focused on high-scale batch streaming data processing reliable data products and analytics-ready datasets that enable prediction agentic workflows BI reporting and measurement. You will partner closely with backend ML and product teams to deliver trusted well-modeled data with strong performance quality and observability.

What Youll Do

• Build data pipelines: Develop robust batch and streaming pipelines (Kafka/Kinesis) to ingest transform and enrich large-scale event data (impressions clicks conversions costs identity signals).
• Create data aggregates & marts: Design and maintain curated aggregates and dimensional models for multiple consumersprediction models agents BI dashboards and measurement workflows.
• Data modeling & contracts: Define schemas data contracts and versioning strategies to keep downstream systems stable as sources evolve.
• Data quality & reliability: Implement validation anomaly detection backfills and reconciliation to ensure completeness correctness and timeliness (SLAs/SLOs).
• Performance & cost optimization: Optimize compute/storage for scale (partitioning file sizing incremental processing indexing) balancing latency throughput and cost.
• Orchestration & automation: Build repeatable workflows with scheduling/orchestration (e.g. Airflow Dagster Step Functions) and CI/CD for data pipelines.
• Observability for data systems: Instrument pipelines with metrics logs lineage and alerting to accelerate detection and root-cause analysis of data issues.

Security & governance: Apply least-privilege access PII-aware handling and governance controls aligned with enterprise standards.

5 years building production data pipelines and data products (batch and/or streaming) in a high-scale environment.

Strong experience with SQL and data modeling (dimensional modeling star/snowflake schemas event modeling).

• Hands-on experience with streaming systems (Kafka preferred) and/or AWS Kinesis including event-driven designs.
• Proficiency in one or more languages used for data engineering (Python Java Scala or Go).
• Experience with distributed data processing (Spark Flink or equivalent) and performance tuning at scale.
• Experience with AWS data services and cloud-native patterns (S3 Glue/EMR Athena Redshift etc. as applicable).
• Familiarity with lakehouse/table formats and large-scale storage patterns (e.g. Parquet; Iceberg/Hudi/Delta are a plus).
• Experience with orchestration/workflow tooling (Airflow/Dagster/Step Functions) and CI/CD for data workloads.
• Strong data quality/observability practices (tests monitoring lineage; understanding of SLAs/SLOs).
• Experience with SQL NoSQL data stores (e.g. Postgres/MySQL; DynamoDB/Cassandra/Redis) and choosing the right store per use case.

Clear communicator and collaborator; able to work with mixed audiences and translate needs into reliable data interfaces.

• AdTech / programmatic advertising domain knowledge: DSP/SSP/exchange/RTB concepts and data flows.
• Experience building measurement pipelines (attribution incrementality lift or experimentation analytics).

Experience supporting ML feature stores offline/online feature generation or model training datasets.

• Experience with real-time analytics stores (Druid/ClickHouse/Pinot) and high-cardinality aggregation strategies.
• Deep knowledge of data governance/privacy including PII handling and consent-aware data processing.
• Open-source contributions publications or conference speaking.
• BS/MS in CS/Engineering or equivalent practical experience.
