Database Reliability Engineer (Junior) - HK

Your mission

We are looking for a motivated Junior Database Reliability Engineer (DBRE) to join our expanding IT Operations team. The successful candidate will be part of a large global multi-international organization working with an array of NoSQL database platforms and applications. You will own the end-to-end lifecycle of NoSQL database instances.

What You Will Do

• Lifecycle Management: Own the full lifecycle of NoSQL database instances, including provisioning, configuration, upgrades, monitoring, performance tuning, and decommissioning.

• Provisioning & Deployment: Use Infrastructure-as-Code tools (Terraform, Ansible, Puppet) to provision and manage NoSQL clusters in a mixture of containerized (Docker/Kubernetes) and non-containerized environments.

• Monitoring & Observability: Implement and maintain monitoring dashboards, alerting, and health checks for distributed NoSQL clusters to enable proactive incident detection and resolution.

• Performance Engineering: Profile server resource usage, analyze query and cluster-level performance, identify bottlenecks, and implement data models, indexing strategies, and configuration changes to optimize throughput and latency.

• Capacity Planning: Plan and model resource requirements based on usage trends, and recommend right-sizing or scaling actions to prevent capacity-related incidents.

• Incident & Change Management: Follow established change management processes, participate in on-call rotations, and contribute to post-incident reviews to drive long-term reliability improvements.

• Cross-Data Centre Replication: Support replication and failover configurations across data centres to ensure high availability and disaster recovery.

• Automation: Develop and maintain automation scripts (Shell, Python) and tooling to reduce manual operational overhead and improve consistency.

• Documentation: Prepare clear, well-structured documentation covering database architecture, runbooks, procedures, and operational standards.

• Collaboration: Work closely with SREs, platform engineers, application teams, and business stakeholders to understand requirements and deliver reliable database services.
