Senior Database Reliability Engineer - Global Infrastructure

Senior Database Reliability Engineer – Global Infrastructure
Job Description
At i3D.Net, we provide world-class global coverage with one of the most interconnected networks in the world. Our solutions focus on low latency, zero packet loss, and unmatched scalability, enabling seamless experiences for millions of users worldwide. With dedicated support, bespoke solutions, and cutting-edge technology, we deliver reliable, cost-efficient infrastructure that empowers game developers and businesses to scale effortlessly. Partnering with major names like Nvidia, DuckDuckGo, and Ubisoft, we are shaping the future of gaming and network technology.Why your role mattersAs a Senior Database Reliability Engineer, you own the availability, scalability, and performance of our MariaDB/MySQL platforms that power real time and latency sensitive services across i3D.Net ‘s global infrastructure.You design, build, and operate highly available database platforms that are reliable, observable, and easy for our internal engineering teams to consume. From provisioning new database clusters and automating operations to improving performance and supporting mission critical production workloads, you play a key role in ensuring our services remain fast, resilient, and always available.Because i3D.Net operates its own global infrastructure, you work across the full technology stack. Alongside database engineering, you’ll work closely with Linux, Kubernetes, Infrastructure-as-Code, and platform automation to build modern database services rather than simply administer databases.Key ResponsibilitiesDesign and build database platforms: You design, build, and evolve highly available RDBMS platforms, ensuring they are resilient, scalable, and aligned with platform standards across multiple environments.Operate and optimize database clusters: You manage multi-environment database clusters, including replication, failover, backups, and performance tuning, using components such as Kubernetes and load balancers.Automate database operations: You automate database provisioning, configuration, upgrades, and maintenance using IaC, reducing manual effort and increasing consistency across environments.Linux and systems ownership: You take responsibility for the Linux systems running database workloads, handling day-to-day operations, troubleshooting, and system-level tuning in bare metal and hybrid setups.CI/CD for database platforms: You integrate database changes into CI/CD pipelines, supporting safe and repeatable deployments, schema changes, and configuration updates across staging and production.Monitoring and observability: You implement and maintain monitoring and alerting for database platforms using tools such as Prometheus and Grafana, ensuring clear visibility into performance, capacity, and reliability.Security and reliability: You apply security best practices to database platforms, including access control, encryption, and compliance requirements, while continuously improving availability and recovery processes.Collaboration and knowledge sharing: You work closely with platform, DevOps, and application teams, sharing knowledge, improving internal tooling, and supporting incident reviews and continuous improvement.Databases: MariaDB/MySQL, multi-node clusters, replication, backups and recoveryInfrastructure and tooling: Linux (bare metal and hybrid), Docker, Kubernetes, Ansible, GitHub ActionsObservability: Prometheus, Grafana, logging and alerting stacksPractices: Infrastructure as Code, CI/CD, Agile ways of working, you build it, you deploy it, you support it.What success looks like in the first yearDatabase platforms are stable, scalable and consumable by our systems and teamsManual database operations are largely automatedPerformance and availability issues are detected earlier and resolved fasterBackup, recovery, and failover processes are reliable and well testedYou are a trusted point of knowledge for database and platform topics within the teamDatabase Engineering experience: You have 5+ years of hands‑on experience managing production database platforms, preferably MariaDB, MySQL and PostgreSQL, with strong requirements around uptime, performance, and data integrity.Linux & Kubernetes: You are comfortable operating Linux systems, especially in on‑premise or hybrid environments, and regularly troubleshoot issues spanning storage, networking, and system resources.Automation and Infrastructure-as-Code: You use tools like Ansible and Terraform to automate database and infrastructure workflows and avoid manual configuration wherever possible.CI/CD and platform integration: You have experience integrating databases into CI/CD pipelines and working alongside application and platform teams to support reliable releases. Experience with GitHub Actions is a plus.Monitoring and observability: You have worked with Prometheus and Grafana in production environments and understand how to monitor database health, performance, and capacity effectively.Communication: Strong English communication skills, both written and spoken, are required for regular collaboration with our international teams and to clearly explain technical issues. Knowledge of French is plus.Collaboration and mindset: You enjoy working in platform or SRE style teams, contributing to documentation and tooling, and supporting others through reviews, incidents, and shared learning.Remote vs onsite: This is a hybrid role, so you’ll spend some time working onsite at our Montréal office. You’ll need to be based in Montréal or the surrounding area and have valid authorization to work in Canada.
