  • Diagnose and resolve system bottlenecks, optimize database schemas and queries (PostgreSQL/SQLAlchemy, Oracle)
  • Create maintainable, modular object models and interfaces, ensuring a clean and well-structured codebase
  • Develop secure, performant RESTful APIs with robust validation and error handling
  • Develop/modify PL/SQL, SQL Views, stored procedures, and database triggers
  • Mentor the team, conduct rigorous code reviews, and establish high standards for documentation and testing
  • Develop test cases and perform unit testing
Requirements:
  • 5+ years of professional experience in Python-based backend development
  • Proven track record in designing microservices or distributed systems, with an understanding of load balancers, proxies, and caching layers
  • Advanced ability to identify and resolve performance issues, including managing concurrency and optimizing memory usage in Python
  • Expert-level knowledge of modern Python frameworks (FastAPI, Django, or Flask)
  • Deep understanding of relational databases (PostgreSQL, Oracle) and ORMs (SQLAlchemy), with experience in optimizing complex queries
  • Familiarity with containerization (Docker) and deploying Python applications to the cloud
  • Experience developing in an Agile project methodology
  • Good knowledge in DevOps tools like Jenkins, Artifactory, and GitHub/Bit Bucket
  • Strong analytical, troubleshooting, and problem-solving skills
Desired Skills:
  • Experience with OCR and NLP technologies
  • 2+ years of experience with Data Analysis
  • Compliance or Operational Risk experience
  • Knowledge of Informatica, Autosys, or Unix Concepts
  • Experience with Jira

Pay range: $58.26 - $66.26 per hour
