The environment is highly collaborative and product-driven, working closely with product, risk, finance, and compliance teams to translate complex regulatory and business requirements into reliable technical solutions. This is a hands-on role for an engineer who enjoys solving deep technical problems, improving system reliability, and building infrastructure that directly impacts global revenue and customer trust. Accountabilities: Lead the design and development of backend features for high-availability systems supporting payments, subscription billing, settlement, refunds, and reporting. 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.
