• Build and maintain integrations with external payment processors, card networks, and alternative payment methods.
• Design scalable, secure, and maintainable service-oriented architectures with a strong focus on reliability and performance.
• Debug and resolve complex production issues across money movement flows, ensuring system stability and minimal downtime.
• Break down large technical initiatives into incremental, deliverable tasks suitable for agile development cycles.
• Participate actively in architecture discussions, design reviews, and code reviews to maintain high engineering standards.
• Collaborate with cross-functional teams (Product, Risk, Finance, Compliance) to ensure regulatory and business requirements are properly implemented.
• Improve CI/CD pipelines, testing strategies, and deployment processes to enhance delivery speed and system quality.
• Mentor and support junior engineers while promoting best practices in coding, testing, and system design.
• Drive continuous improvement by identifying performance bottlenecks, operational risks, and opportunities for system optimization.
