Senior Backend Engineer

Why PayNet / Why Now

• Strengthen backend platforms critical to onboarding participants into Malaysia’s payment ecosystem
• Scale and stabilize systems as onboarding volumes, complexity, and integration demands increase
• Reduce long‑term operational and performance risk through better backend architecture and design
• Own backend decisions that directly affect platform reliability, security, and partner experience

TL;DR

• Design and own backend services that underpin critical participant onboarding platforms
• Build scalable, secure, and high‑performance systems used at national scale
• Act as a senior technical owner, shaping architecture and delivery standards
• Mentor engineers while ensuring production‑grade reliability and maintainability

Why This Role Matters

• Backend systems directly impact the reliability and scalability of national payment onboarding
• Poor architectural decisions create long‑term operational risk and rework
• Senior engineers set the technical bar for quality, performance, and security
• Strong backend ownership enables faster delivery without compromising stability

What You Will Actually Do
