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 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. 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. What you’ll bring * 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.) is a plus. * Experience with Git and working in an open-source version control workflow. * Working knowledge of *nix system tuning (kernel parameters, filesystem, memory, CPU) is a plus. * Strong interpersonal skills, the ability to work in a team, and a proactive problem-solving mindset. * Up-to-date knowledge of database reliability best practices and industry standards. * Ability to plan and model resource requirements from high-level specifications. * Training or certifications in cloud platforms (AWS/Azure/GCP) or NoSQL databases is a plus. * Able to communicate fluently in written and spoken English. #J-18808-Ljbffr
