• Real-Time Event Streaming: Implement and maintain event-driven streaming pipelines using Apache Kafka to deliver low-latency data across microservices.

• Lakehouse Governance: Structure and manage our Data Lakehouse, organizing schemas, enforcing data quality rules, and optimizing query performance for downstream BI and AI teams.

## Competencies and Qualifications

• Advanced SQL: Write complex window functions and Common Table Expressions (CTEs); analyze and optimize query execution plans for speed.
• Backend Programming: Strong coding proficiency in Python (for scripting/orchestration) OR Scala/Java (for high-performance Spark/Kafka engineering).
• Distributed Systems (Spark/Kafka): Solid understanding of how distributed compute works—specifically Apache Spark (handling data skew, transformations vs. actions) and Apache Kafka (brokers, topics, partitioning, offsets).
• Lakehouse Architectures: Foundational knowledge of open table formats like Apache Iceberg, or Delta Lake, and how to model data across Bronze, Silver, and Gold storage layers.

• Infrastructure: comfortable with basic Linux admin & bash commands, monitoring and automation for data services.
