Principal Engineer - Hypervisors, Backup & UNIX Systems

Why PayNet / Why Now

• Build the infrastructure behind Malaysia’s national payments network, powering rails Malaysians use daily, including DuitNow, FPX, JomPAY, and MyDebit.
• Operate at true national scale (PayNet reports 8.44B transactions processed in 2025), where architecture decisions materially affect uptime, speed, and trust.
• Join a public-good operator that reinvests surplus back into making the country’s payment infrastructures more resilient, competitive, and accessible.
• Step in at an inflection point: PayNet has been shifting from legacy/private connectivity toward internet-based API connectivity and a cloud-based computing model, raising the bar for security and platform engineering.

TL; DR

• Own the future-state infrastructure architecture behind Malaysia’s most critical payment rails.
• Lead large-scale virtualization, automation, and migration initiatives with national impact.
• Work on always-on, mission-critical systems where your decisions truly matter.
• Combine deep technical ownership with long-term platform strategy.

Why This Role Matters

• Malaysia’s core payment systems depend on resilient, low-latency infrastructure at scale.
• Infrastructure decisions here directly affect availability, security, and public trust.
• This role reduces systemic risk while enabling growth, innovation, and automation.
• Strong architecture leadership now prevents outages, bottlenecks, and technical debt later.

What You Will Actually Do

• Own and shape PayNet’s future-state infrastructure architecture across compute, storage, virtualization, and backup.
• Design and operate highly available, low-latency virtualization platforms supporting mission-critical payment systems.
• Lead multi-year migrations of core services (e.g., DuitNow, FPX, JomPAY) with minimal disruption.
• Build automation frameworks that enable repeatable, secure, and scalable infrastructure operations.
• Drive observability and performance management to ensure capacity, reliability, and uptime.
• Act as technical lead across deployment, integration, and cross-functional infrastructure initiatives.

Examples of This Role in Practice

• Designing a new virtualization platform and migrating live payment services without customer impact.
• Automating patching and hardening across hundreds of servers to reduce operational risk.
• Diagnosing performance bottlenecks during peak transaction periods and resolving them permanently.
• Partnering with security and network teams to implement resilient, compliant infrastructure designs.
• Proactively scaling infrastructure ahead of national usage spikes or regulatory changes.

What Will Help You Succeed

Required

• Strong hands-on experience with RedHat Linux and Windows Server in production environments.
• Proven ability to design and deploy highly available virtualization platforms from the ground up.
• Experience automating infrastructure using tools like Ansible, Chef, or Puppet.
• Practical experience with enterprise platforms such as Active Directory, DNS, LDAP, Jenkins, Terraform, and monitoring tools.

Helpful

• Certifications such as RHCE or LPIC demonstrating advanced Linux expertise.
• Experience in financial services or telecommunications with strict uptime and security requirements.
• Exposure to AWS or GCP, particularly in hybrid infrastructure environments.
• Familiarity with modern CI/CD, monitoring, and logging stacks (e.g., Grafana, Prometheus, ELK).
• Experience supporting enterprise application and web platforms (e.g., Nginx, HAProxy, JBoss, WebLogic).
