This role is well suited to an engineer who enjoys deep technical problem-solving, operates comfortably in production environments, and wants to improve how large-scale cloud systems are built and run.

Responsibilities
What You’ll Do

- Design and evolve infrastructure and services for reliability, scalability, and performance.

- Forecast capacity needs and identify risks before they affect customers.

- Partner with software engineering teams to improve service architecture and operational readiness.

- Lead incident response, troubleshooting, root-cause analysis, and post-incident improvements.

- Build automation, tooling, and scripts that reduce manual effort and improve reliability.

- Monitor service health, performance, and availability, and act on emerging trends.

- Improve observability, operational workflows, and service-level performance.

- Evaluate new tools and technologies that can improve reliability, efficiency, or scale.

- Contribute to technical guidance, knowledge sharing, and the development of other engineers.

Required Skills/Experience
What You’ll Bring

- This role is open only to Singapore Citizens, as the scope of work involves government projects that require citizenship for clearance purposes.

- Strong experience in site reliability engineering, software engineering, infrastructure, or cloud operations.

- Deep troubleshooting and incident-response experience across complex production environments.

- Strong programming or scripting skills and hands-on automation experience.

- Experience with infrastructure, virtualization, security tooling, and database reliability.

- Strong understanding of monitoring, capacity planning, service health, and SLOs.

- Ability to diagnose issues across multiple services and technical domains.
