Senior Platform Engineer (DBaaS)

About this role

<div class="content-intro"><p class="p1"><span style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"><strong>Rumble </strong>is <em>the</em> Freedom-First technology platform. We proudly offer a video platform, cloud services, advertising solutions, and a non-custodial cryptocurrency wallet.</span></p></div><p><span data-contrast="none">Rumble Cloud is building a DBaaS platform that makes reliable, high-performance databases available to our internal teams and customers without the usual operational friction. As a Senior Platform Engineer (DBaaS), you’ll own the Kubernetes-based platform that runs our managed database workloads on OpenStack, focusing on orchestration, reliability, automation, and security rather than deep engine-specific tuning.</span></p> <p><span data-contrast="none">This is first and foremost a Kubernetes and cloud platform role. You’ll design and operate DBaaS as a multi-tenant, stateful service: making sure clusters are healthy, databases are highly available, storage and networking are robust, and the platform can scale quickly as adoption grows. You’ll partner closely with database specialists for engine-level decisions, but your core impact is in how you provision, harden, monitor, and evolve the infrastructure that powers the service.</span></p> <p><span data-contrast="none">You’ll collaborate with Rumble Cloud engineering, SRE, and database architecture teams to take DBaaS from initial hardening through launch and into scale-out: defining SLIs/SLOs, building automation and runbooks, integrating with OpenStack services, and serving as a senior escalation point when platform issues impact customers. If you enjoy running Kubernetes in production, working on mission-critical infrastructure, and building platforms that other teams depend on every day, this role is for you.</span></p> <h2 id="responsibilities" class="font-editorial font-bold mb-2 mt-4 [.has-inline-images_&]:clear-end text-base first:mt-0">Responsibilities</h2> <ul> <li><span data-contrast="none">Own and operate the Kubernetes platform that powers DBaaS, including cluster provisioning, upgrades, capacity planning, and day-to-day reliability.</span></li> </ul> <ul> <li><span data-contrast="none">Run relational databases (e.g., PostgreSQL, MySQL, MariaDB) as managed stateful workloads on Kubernetes using operators, StatefulSets, and persistent storage, with a focus on HA, backup/restore, and security.</span></li> </ul> <ul> <li><span data-contrast="none">Integrate DBaaS with the underlying OpenStack infrastructure (Nova, Cinder, Neutron), ensuring networking, storage, and compute resources are configured correctly for multi-tenant database workloads.</span></li> </ul> <ul> <li><span data-contrast="none">Design and implement automation and infrastructure-as-code for the platform using tools such as Terraform, Ansible, and Python/Bash, covering provisioning, configuration, upgrades, and lifecycle management.</span></li> </ul> <ul> <li><span data-contrast="none">Build and maintain observability for DBaaS using Prometheus, Grafana, and related tools, including metrics, logs, alerts, and dashboards that surface health and performance of both Kubernetes and database workloads.</span></li> </ul> <ul> <li><span data-contrast="none">Develop and document runbooks, SRE practices, and incident response procedures for DBaaS, and participate in on-call rotations as a senior escalation point.</span></li> </ul> <ul> <li><span data-contrast="none">Work with database architects and application teams to define SLIs/SLOs, capacity and performance expectations, and safe change-management processes for database schemas and platform upgrades.</span></li> </ul> <ul> <li><span data-contrast="none">Implement and enforce security best practices across the platform, including RBAC, network policies, encryption at rest and in transit, secrets management, and access controls for multi-tenant environments.</span></li> </ul> <ul> <li><span data-contrast="none">Collaborate with early customers and internal stakeholders to understand their requirements, support onboarding to DBaaS, and guide them in using the platform effectively.</span></li> </ul> <ul> <li><span data-contrast="none">Continuously improve the platform by identifying reliability, performance, and usability bottlenecks and delivering iterative enhancements that make DBaaS more robust and easier to operate.</span></li> </ul> <h2 id="qualifications" class="font-editorial font-bold mb-2 mt-4 [.has-inline-images_&]:clear-end text-base first:mt-0">Qualifications</h2> <ul> <li><span data-contrast="none">Hands-on experience running production Kubernetes clusters at scale, including cluster operations, upgrades, and troubleshooting.</span></li> </ul> <ul> <li><span data-contrast="none">Experience operating stateful workloads on Kubernetes (operators, StatefulSets, storage classes, persistent volumes, backup and restore workflows).</span></li> </ul> <ul> <li><span data-contrast="none">Working experience with at least one relational database engine such as PostgreSQL, MySQL, or MariaDB in a production…
