Job Description
Get to Know the Team
GrabDefence builds technology that helps protect users and businesses from fraud and abuse. Our engineers work across security, infrastructure and product teams to support reliable systems that can scale with evolving threats.
You will join a team that values shared ownership and continuous improvement. Your work will help engineers manage infrastructure securely and spend more time building capabilities that protect customers.
Get to Know the Role
As a Lead Software Reliability Engineer, you will drive the infrastructure and operational tooling that support GrabDefence. You will partner closely with Grab's central site reliability engineering (SRE) team to manage Amazon Web Services (AWS) resources, support infrastructure migrations and make operations easier through automation and AI-enabled tools.
You will report to Senior Engineering Manager in Singapore. This role is based in Beijing, China. You will have opportunities to shape infrastructure strategy, lead technical initiatives and guide other engineers.
If you enjoy building secure infrastructure and making complex operations simpler, we encourage you to apply.
The Critical Tasks You Will Perform
• You will design and manage AWS infrastructure—including networking, storage, compute and databases—to support reliable and scalable GrabDefence services.
• You will partner with the central SRE team to deliver infrastructure capabilities, clarify ownership and align operational practices across shared and GrabDefence environments.
• You will plan and execute infrastructure maintenance and migrations, managing dependencies and rollback plans to minimise service disruption.
• You will implement infrastructure policies and access controls, including identity and access management, least-privilege permissions and configuration guardrails.
• You will build and improve infrastructure management and orchestration tools that make provisioning, changes and routine operations easier and more consistent.
• You will use generative AI and develop AI-enabled tooling where appropriate to accelerate investigations, documentation and operational workflows, with safeguards and human review for consequential changes.
• You will improve reliability through monitoring, incident response, root-cause analysis and automation that reduces recurring operational work.
