Python / ML Developer - Remote (EST Hours)

ISTA Personnel Solutions is a dynamic and fast-growing BPO company. We are not a recruitment agency - we operate as a dedicated extension of our clients’ teams, delivering high-quality service with precision, efficiency, and a personal touch.

We are recruiting a hands-on Python Developer to support a U.S.-based client in the nursing industry. This fully remote role is best suited to a developer who is highly comfortable writing Python scripts from scratch, quickly manipulating data, and building ad hoc data pipelines and API integrations.

This role involves daily Python scripting and data wrangling, rather than building full platforms or applications. The ideal candidate is someone for whom Pandas and NumPy are second nature, and who enjoys solving data problems quickly and collaboratively.

• Experience performing data cleaning, transformation, and analysis
• Solid understanding of Python data structures, indexing, and data operations
• Experience working with APIs and JSON data
• Experience using Matplotlib or similar libraries for data visualization
• Strong problem-solving skills and ability to debug data workflows
