We are looking for a motivated Database Reliability Engineer (DBRE) to join our Clients expanding IT Operations team. The successful candidate will be part of a large general 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.

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. 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. 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. 2+ years of experience in IT operations, site reliability, database administration, or a related engineering role. ~ Solid understanding of NoSQL databases (e.g., Cassandra, Elasticsearch, MongoDB) — hands-on experience with at least one of these is expected. ~ Strong Linux administration skills and comfort working in shell-based environments. ~ Experience with Infrastructure-as-Code and configuration management tools (Terraform, Ansible, Puppet). ~ Proficiency in scripting languages (Shell, Python, or Ruby). ~ Familiarity with Docker and/or Kubernetes for containerized database deployments. ~ Basic knowledge of SQL databases (MySQL, PostgreSQL, Oracle, etc.) Experience with Git and working in an open-source version control workflow. ~ Up-to-date knowledge of database reliability best practices and industry standards. ~ Training or certifications in cloud platforms (AWS/Azure/GCP) or NoSQL databases is a plus.
