Job description

Senior Python Developer (SAS Background Preferred)

We are seeking an experienced Python Developer with a strong understanding of SAS-based data workflows and deep hands-on expertise in Python. This is a hands-on contributor role (not a leadership position) focused on building, optimizing, and maintaining data processing solutions.

Required Experience & Skills

Core Python Development

  • Several years of professional experience developing production-grade Python code.
  • Strong proficiency with Python data libraries such as pandas, NumPy, and related ecosystems.
  • Comfortable working independently on complex data processing tasks.

Advanced Data Manipulation

  • Expertise in merging and joining large datasets efficiently using merge(), join(), and related techniques.
  • Strong understanding of data alignment, indexing strategies, and memory-efficient transformations.
  • Experience handling complex data structures and edge cases during large-scale data integration.

Scalability & Performance

  • Experience processing large or out-of-memory datasets, including:
  • Parallel or distributed processing (e.g., multiprocessing, Dask, Spark, or similar).
  • Performance tuning to replace or improve upon SAS I/O and batch optimizations.
  • Ability to profile code and identify bottlenecks in data pipelines.

Automation & DevOps

  • Experience automating data workflows and jobs using Python.
  • Familiarity with scheduling, CI/CD pipelines, and environment management.
  • Comfortable working in Linux-based environments and with version control systems (e.g., Git).

Testing & Validation

  • Strong understanding of testing strategies for data and analytics code.
  • Experience writing unit tests, integration tests, and validation checks to ensure data accuracy and consistency.
  • Ability to validate Python-based outputs against legacy SAS results when required.

Jupyter & Collaboration

  • Hands-on experience working in Jupyter Notebooks for development, analysis, and documentation.
  • Ability to write clear, reproducible notebooks that communicate logic and results effectively.

Nice to Have

  • Prior experience translating or modernizing SAS workflows into Python-based solutions.
  • Exposure to cloud platforms or distributed data environments.
