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.

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.

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.

Responsibilities

• Own and operate the Kubernetes platform that powers DBaaS, including cluster provisioning, upgrades, capacity planning, and day-to-day reliability.

• 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.

• Integrate DBaaS with the underlying OpenStack infrastructure (Nova, Cinder, Neutron), ensuring networking, storage, and compute resources are configured correctly for multi-tenant database workloads.

• 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.

• 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.

• Develop and document runbooks, SRE practices, and incident response procedures for DBaaS, and participate in on-call rotations as a senior escalation point.

• 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.

• 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.

• Collaborate with early customers and internal stakeholders to understand their requirements, support onboarding to DBaaS, and guide them in using the platform effectively.

• Continuously improve the platform by identifying reliability, performance, and usability bottlenecks and delivering iterative enhancements that make DBaaS more robust and easier to operate.

Qualifications

• Hands-on experience running production Kubernetes clusters at scale, including cluster operations, upgrades, and troubleshooting.

• Experience operating stateful workloads on Kubernetes (operators, StatefulSets, storage classes, persistent volumes, backup and restore workflows).

• Working experience with at least one relational database engine such as PostgreSQL, MySQL, or MariaDB in a production environment.

• Strong skills in automation and infrastructure-as-code, using tools such as Terraform, Ansible, and scripting languages (Python and/or Bash).

• Solid understanding of Linux systems, networking fundamentals, and security concepts in cloud-native environments.

• Ability to debug complex issues that span Kubernetes, storage, networking, and database workloads, and to communicate findings clearly to both technical and non-technical stakeholders.

Preferred Qualifications

• Experience running Kubernetes on OpenStack, including Nova, Cinder, and Neutron, or similar private cloud platforms.

• Background operating a DBaaS or large-scale, multi-tenant database platform where reliability and isolation are critical.

• Familiarity with Ceph storage, OVN/OVS networking, and observability tools such as Prometheus, Grafana, or Zabbix.

• Experience building SRE practices for platform services, including SLIs/SLOs, error budgets, and incident postmortems.

• Comfort working in high-growth, mission-critical infrastructure environments where priorities can evolve quickly.
