Python Developer at Systems Technologies

Open Systems Technologies is recruiting a Python Developer on behalf of a major financial firm in New York, NY
. This full-time position calls for an engineer who can build and maintain backend systems and data pipelines that support critical business decisions in a high-stakes environment.

$150,000 – $200,000 per year

• Bachelor's Degree in Computer Science, Engineering, or a related field
• Minimum 5 years of hands-on technical experience
• Strong proficiency in Python
• Solid understanding of relational databases and SQL
• Excellent analytical skills with keen attention to detail
• Strong verbal and written communication abilities

• Direct engagement with a major financial institution where system performance and reliability are non-negotiable
• Competitive salary range reflecting senior-level expectations
• Full-time placement with long-term growth potential

• Be ready to discuss database architecture: Given the financial sector's reliance on relational databases, expect questions on query optimization, schema design, and transaction integrity
• Highlight finance-adjacent Python work: If you have built data pipelines, ETL processes, or trading system backends using libraries like pandas, Num Py, or SQL Alchemy, make those projects prominent on your resume
• Emphasize SQL depth: Recruiters staffing for financial clients look for candidates who can write complex joins, window functions, and stored procedures without relying on an ORM as a crutch
• Prepare for systems-thinking questions: Financial firms value developers who understand concurrency, error handling, and data consistency under load
• Showcase communication examples: Senior developers in finance often bridge technical and business teams, so be ready to discuss times you translated complex technical concepts for non-technical stakeholders
