Site Reliability Engineer

Job Description

We are seeking a highly experienced and proactive Senior Site Reliability Engineer to join our engineering team in Malaysia. The successful candidate will own the reliability, scalability, and performance of our production systems — with deep expertise in Kubernetes-based infrastructure, cloud platforms (AWS/Azure), configuration management with Ansible, and fullstack observability covering logging, tracing, and metrics. Beyond hands-on platform work, this role carries technical leadership responsibilities including mentoring engineers, defining SRE standards, and driving a culture of reliability and operational excellence across the organization. The candidate will be responsible for managing cloud resources, observability pipelines, and incident response for systems that serve Vietnamese clients and integrate with Vietnamese platforms. Fluency in Vietnamese is required to collaborate with Vietnam-based engineering teams, read technical documentation written in Vietnamese, and lead incident bridges involving Vietnamese stakeholders

o Implement and manage centralized logging infrastructure using the ELK Stack (Elasticsearch, Logstash, Kibana) or Loki/Grafana for log aggregation, search, and analysis

o Deploy and maintain distributed tracing solutions using Jaeger, Tempo, or OpenTelemetry to provide end-to-end request visibility across microservices

o Instrument applications and infrastructure for OpenTelemetry-compliant telemetry collection (metrics, logs, traces) in collaboration with development teams

o Define and implement SLOs, SLIs, and error budgets based on observability data, ensuring alerting is actionable, noise-free, and tied to real user impact

o Continuously improve dashboards, runbooks, and alert thresholds to provide meaningful, real-time visibility into system health and performance Incident 

Management & Production Support

o Lead the response to major production incidents, coordinating cross-team investigation and resolution end-to-end

o Leverage observability tooling (metrics, logs, traces) to rapidly diagnose and resolve incidents with minimal MTTR

o Author detailed post-mortem reports and drive systemic preventive measures to eliminate recurring issues

o Establish and mature on-call rotations, escalation procedures, and incident response playbooks
