• Develop high-performance transformation logic using PySpark, Python, and SQL for distributed, large-scale data processing.
• Partner with data scientists and analysts to operationalize statistical models and custom algorithms in secure production environments.
• Diagnose and resolve system bottlenecks to maintain high performance across both cloud and classified compute environments.
• Create data quality and validation frameworks and implement automated pipeline monitoring to protect the integrity of inputs feeding analytics models.

Requirements

• 5+ years of experience in data engineering or big data.
• Hands-on experience with PySpark, Python, and SQL.
• Experience building complex data pipelines and transformations within distributed platforms such as Palantir Foundry.
• Experience structuring, formatting, and optimizing large-scale datasets for use by engineering teams and mathematical or statistical models.
