• Implement automated testing (unit, integration, and component) and reusable frameworks for logging, monitoring, and observability
• Collaborate cross-functionally with product owners, architects, and quality engineers to refine requirements and deliver robust solutions
• Troubleshoot complex production issues using logs, metrics, and traces, and implement durable fixes to improve system stability
• Apply secure coding practices, input validation, and error handling to protect sensitive customer and transaction data
• Participate in code reviews and design discussions to elevate code quality, maintainability, and security standards
• Support deployments, monitor system performance, and continuously improve services based on production telemetry and user feedback

Requirements:

• 8–12 years of hands-on software engineering experience delivering production-grade solutions using modern architectures
• Strong proficiency in Java and Python, including multithreading, asynchronous programming, and data store integration
• Experience building or integrating AI agents or intelligent automation solutions interacting with APIs, messaging systems, or workflows
• Solid understanding of object-oriented design, data structures, algorithms, and microservices architecture
• Experience with RESTful services, event-driven systems, and CI/CD pipelines with automated testing and version control
• Experience in cards, payments, or financial services domains, including transaction flows, authorization, and settlement
• Familiarity with monitoring, logging, and observability frameworks for distributed systems
• Experience implementing secure coding practices, input validation, and data protection controls
• Strong troubleshooting skills with the ability to analyze logs, metrics, and traces to resolve complex production issues
• Ability to communicate complex technical concepts clearly to both technical and non-technical stakeholders
