Juspay is a fast‑growing payments technology firm headquartered in Bangalore. Founded in 2012, the company has built a reputation for delivering highly reliable, secure, and scalable payment infrastructure to merchants, banks, and fintech players across India and beyond. Its platform powers millions of transactions daily, handling everything from card payments to UPI, digital wallets, and emerging payment methods. With a strong focus on innovation, Juspay invests heavily in research, functional programming paradigms, and open‑source contributions, making it a coveted destination for engineers who want to work on cutting‑edge financial technology. As a Backend Software Development Engineer, you will become an integral part of the core payments team. Your primary mission will be to design, develop, and maintain the backend services that orchestrate payment flows, ensure high availability, and meet stringent latency requirements. You will collaborate with product managers, frontend engineers, and security specialists to translate business requirements into robust, production‑grade code. The role offers exposure to large‑scale distributed systems, real‑time data pipelines, and complex API ecosystems that serve thousands of concurrent users. Key Responsibilities: 1. Design and implement backend business logic for payment processing and settlement. 2. Build, document, and version APIs that enable seamless integration with merchants, banks, and third‑party services. 3. Develop and maintain UPI, card, and wallet integration modules, ensuring compliance with regulatory standards. 4. Optimize system performance, latency, and throughput through profiling, caching, and efficient data structures. 5. Contribute to the reliability engineering effort by writing automated tests, monitoring alerts, and incident‑response playbooks. 6. Participate in code reviews, enforce coding standards, and mentor junior developers. 7. Collaborate on system design discussions, focusing on scalability, fault tolerance, and data consistency. 8. Stay updated with functional programming concepts and apply them to improve code readability and maintainability. 9. Work closely with the security team to embed best practices for authentication, encryption, and fraud detection. 10. Assist in the continuous improvement of CI/CD pipelines and deployment automation. Tech Stack: The backend primarily uses Java, Kotlin, and Go, with functional programming libraries such as Vavr. Services run on Kubernetes, communicate via gRPC/REST, and persist data in PostgreSQL and Redis. Observability is achieved through Prometheus, Grafana, and Jaeger. Growth Path: Successful engineers can progress to Senior Engineer, Lead Engineer, or Architecture roles, with opportunities to lead product modules or move into specialized domains like fraud detection or performance engineering. Juspay’s flat hierarchy and mentorship culture accelerate learning and career advancement. Why Join Juspay: You will work on mission‑critical payment systems that impact millions of users, gain deep expertise in fintech, and be part of a culture that values innovation, autonomy, and continuous learning. The company offers competitive compensation, flexible work arrangements, and a vibrant community of engineers passionate about building the future of digital payments.
