• Contribute to Malaysia's national payment infrastructure that processes millions of transactions daily and supports critical economic activities.
• Play a key role in the modernization and continuous evolution of NextSwitch, one of the country's most important financial technology platforms.
• Join an organization where reliability, resilience, security, and operational excellence are non-negotiable engineering principles.
• Influence quality engineering practices at enterprise scale and help shape the future of payment system testing and automation.
• Work alongside highly skilled engineers solving complex challenges in transaction processing, system integration, performance, and platform stability.

TL; DR

• Own and drive the quality engineering strategy for PayNet's mission-critical payment switching platforms.
• Lead automation, performance, and quality initiatives that improve platform reliability and release confidence.
• Partner with engineering, architecture, operations, and business stakeholders to reduce delivery risk and improve software quality.
• Mentor engineers and establish modern testing practices across multiple teams and delivery streams.

Why This Role Matters

• NextSwitch operates as national critical infrastructure where software quality directly impacts payment transactions, financial institutions, and end users nationwide.
• The increasing scale and complexity of transaction processing require advanced automation, performance testing, and quality engineering capabilities.
• This role ensures quality is engineered into the platform throughout the software development lifecycle rather than validated only at the end.
• The role provides technical leadership in establishing testing standards, governance, and automation frameworks across multiple teams.
• The role contributes directly to platform resilience, operational stability, and customer trust.

What You Will Actually Do

• Define and drive quality engineering strategy covering automation, API testing, integration testing, performance testing, and release validation.
• Design, implement, and govern scalable automation frameworks integrated into CI/CD pipelines.
• Lead performance testing initiatives to ensure platform readiness for increasing transaction volumes and peak demand scenarios.
• Collaborate with development, architecture, DevOps, and operations teams to improve platform reliability and reduce production risk.
• Mentor engineers and establish testing standards, best practices, and continuous improvement initiatives across delivery teams.

Examples of This Role in Practice

• Develop a testing strategy to support a major NextSwitch enhancement while maintaining production stability and release confidence.
• Lead end-to-end validation of a new payment service involving multiple banking and ecosystem integrations.
• Establish performance testing frameworks capable of validating transaction throughput, latency, and resilience under production-scale loads.
• Drive automation coverage improvements that significantly reduce manual testing effort and improve release velocity.
• Investigate recurring production defects and implement quality engineering improvements that prevent future occurrences.

What Will Help You Succeed

Required

• Strong experience designing and implementing test automation frameworks using tools such as Selenium, Playwright, Cypress, Robot Framework, or equivalent.
• Hands-on experience with API testing, integration testing, and automated regression testing.
