 * Strong proficiency in Python (OOP, concurrency, data structures) and advanced SQL.
 * Deep production experience with Apache Spark / PySpark (Data Frames, Spark SQL, RDDs).
 * Hands-on experience with cloud data platforms like AWS (EMR, Glue), Azure (Databricks), or GCP.
 * Experience working with Snowflake, Big Query, Redshift, or Synapse.
 * Proficient with Git, Docker, and automated deployment pipelines.

Qualifications We Prefer:

 * PySpark MLlib or deploying Machine Learning models to production.
 * Familiarity with streaming technologies like Apache Kafka or Spark Structured Streaming. Databricks Certified Data Engineer or Apache Spark Developer certifications.

## Description

* Design and deploy robust batch and streaming ETL/ELT pipelines using PySpark and Python.
 * Optimize Spark jobs by tuning configurations, managing partitioning, and resolving data skew or OOM (Out of Memory) errors.
 * Implement modern data lakehouse architectures using Delta Lake, Iceberg, or Hudi.
 * Build and maintain complex workflow DAGs using orchestration tools like Apache Airflow.
 * Develop backend Python services or REST APIs (e.g., Fast API, Flask) to expose processed data to downstream applications.
 * Write clean, modular, and unit-tested code while participating in rigorous code reviews
