Python Developer , Systems Modernization - REMOTE

SUMMARY

Lead the modernization of core data processing systems. Responsible for translating complex legacy SAS logic into robust, high-performance Python solutions. Build and maintain scalable data pipelines that handle large-scale datasets, ensuring that our data products are accurate, well-documented, and optimized for a cloud-native environment. Work with DSD IT Specialists in an integrated team environment.

ESSENTIAL DUTIES & RESPONSIBILITIES

• Analyze existing SAS-based systems and re-implement logic into Python, ensuring functional parity while improving maintainability and scalability.
• Design and develop end-to-end pipelines to read, clean, and transform diverse data formats-including SAS datasets, Parquet, JSON, and SQL-utilizing larger-than-memory processing techniques.
• Profile and refactor code to eliminate bottlenecks.
• Implement parallel computing strategies using libraries such as Dask, multiprocessing, etc. to handle production-scale workloads efficiently.
• Use Python to interface with PostgreSQL for high-volume data storage and retrieval.
• Implement rigorous automated testing and data quality checks (both in-transit and at-rest) to ensure the integrity of critical data assets.
• Maintain high standards for code quality by producing well-documented, readable, and extensible code.
• Actively participate in knowledge sharing and peer reviews to foster a collaborative engineering culture.
• Assist DSD with the implementation of Python code solutions using efficient methodologies to utilize the language's strengths.
• Assist DSD in analyzing existing SAS-based systems to glean functional requirements to develop optimized, Python-based solutions.
• Use Python to read and reformat large datasets.
• Clearly document and verbally communicate through step-by-step procedures, presentations, explanations of Python coding, configuration settings with rationale, shadowing, and other techniques deemed appropriate by current staff and/or management to ensure adequate knowledge transfer.
• Attend branch meetings and share technical knowledge clearly.
• Maintain regular communication with team as required.
• Maintain regular and punctual attendance.
• Perform other duties as assigned.
