Data Engineer

Responsibilities:

• Design and operate batch and streaming data pipelines (ETL/ELT) at production scale.
• Build and maintain training-ready datasets for ML/AI feature pipelines, labeling workflows, and data quality for model training.
• Own the data warehouse/lakehouse stack (e. g., Snowflake, BigQuery, Databricks, Spark) and transformations (dbt).
• Orchestrate workflows (Airflow or equivalent) with strong monitoring and lineage.
• Implement data security and compliance: PII classification, encryption, access controls, retention, and governance (GDPR and similar).
• Partner with AI/data science teams to make data discoverable, trustworthy, and fast.

Requirements:

• 5-7 years in data engineering, ideally within a SaaS environment.
• Hands-on experience preparing data for model/ML training (not just BI/reporting pipelines).
• Strong SQL and Python; deep experience with a modern warehouse/lakehouse and Spark.
• Comfortable integrating data services with a Node.js / TypeScript platform (APIs, events, schemas).
• Pipeline orchestration (Airflow) and transformation (dbt) at scale.
• Demonstrated work under data security and compliance requirements.
• Strong data modeling and data quality fundamentals.

Bonus:

• Streaming (Kafka, Flink, Kinesis) and real-time feature stores.
• MLOps / feature store tooling (Feast, Tecton).
• Experience in a multi-tenant or regulated data environment.
• Non-negotiables: 5-7 years of SaaS data engineering hands-on ML/training data prep, data security, and compliance experience.
