About the Role

As a Senior Python Developer, you will design, develop, and maintain scalable, transactional API‑based systems built on AWS, using modern development practices and full CI/CD automation.

• Participate in design discussions related to microservices, integrations, and cloud architecture (AWS)
• Build and maintain CI/CD pipelines using Git, Jenkins (or similar)
• Ensure best practices in Python development: code quality, testing, maintainability, automation
• Develop, test, and debug APIs integrating with cloud systems and external services
• Monitor system performance and work on improvements in scalability and reliability
