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.
