PayNet / Why Now\nStrengthen backend platforms critical to onboarding participants into Malaysia’s payment ecosystem\nScale and stabilize systems as onboarding volumes, complexity, and integration demands increase\nReduce long-term operational and performance risk through better backend architecture and design\nOwn backend decisions that directly affect platform reliability, security, and partner experience\nTL;DR\nDesign and own backend services that underpin critical participant onboarding platforms\nBuild scalable, secure, and high-performance systems used at national scale\nAct as a senior technical owner, shaping architecture and delivery standards\nMentor engineers while ensuring production-grade reliability and maintainability\nWhy This Role Matters\nBackend systems directly impact the reliability and scalability of national payment onboarding\nPoor architectural decisions create long-term operational risk and rework\nSenior engineers set the technical bar for quality, performance, and security\nStrong backend ownership enables faster delivery without compromising stability\nWhat You Will Actually Do\nDesign and lead architecture for scalable, high-performance backend systems\nDevelop and maintain backend services and RESTful APIs using Java, Golang, or Python\nDesign and optimize database schemas and queries to ensure performance and data integrity\nOwn end-to-end delivery from design through deployment and post-release stability\nReview code, mentor junior engineers, and uphold engineering best practices\nTroubleshoot complex production issues and drive continuous system improvement\nExamples of This Role in Practice\nDesigning a backend service that scales onboarding without latency or failure risk\nRefactoring database queries to remove performance bottlenecks\nLeading code reviews that prevent security or reliability issues\nResolving a critical production incident through deep root-cause analysis\nCollaborating with frontend, DevOps, and product teams to deliver secure solutions\nWhat Will Help You Succeed\nRequired\nStrong proficiency in Java with deep understanding of OOP, SOLID principles, and Design Patterns, along with strong hands-on experience in Spring Boot, including core concepts such as dependency injection, request lifecycle, and framework design decisions.\nProven ability to design and build end-to-end scalable backend systems, including RESTful APIs and overall system architecture.\nStrong understanding of system design principles, including scalability, performance, reliability, and maintainability.\nSolid experience with relational databases (SQL), including schema design, query optimisation, and performance tuning.\nStrong problem-solving ability to analyse, debug, and resolve complex technical issues systematically.\nGood understanding of unit testing and test strategy design.\nAbility to mentor junior engineers, conduct code reviews, and drive engineering best practices.\nExperience working in an Agile environment.\nGood to Have\nExposure to other backend languages/frameworks (e.g. Golang, Node.js)\nExperience with microservices and distributed systems architecture\nExperience with AWS cloud services\nExperience with Linux command-line\nIntegration with third-party APIs and external services\nFamiliarity with CI/CD pipelines and deployment automation\nKnowledge of backend security practices (authentication, authorization, data protection)\nExperience with monitoring, logging, and performance tuning
