Senior Database Administrator - Core Infrastructure

Responsibilities

• Scale and tune high-throughput MariaDB clusters to support continued global expansion and new product initiatives.
• Strengthen high-availability, disaster-recovery, and backup approaches through sound design and regularly validated procedures.
• Reduce manual operational work by building automation, improving process consistency, and enabling safe, low-friction database workflows.
• Improve observability and alert quality by championing meaningful metrics, reducing noise, and ensuring operational clarity across environments.
• Enhance database security through robust access controls, disciplined patching and upgrade practices, and secure operational patterns.
• Contribute to modern platform initiatives, including containerized environments, infrastructure-as-code workflows, and reproducible deployments.
• Partner with service teams to drive better performance patterns, operational readiness, and database hygiene across the engineering organization.
• Participate in our on-call rotations with a long-term focus on making on-call predictable, informed by high-quality signal and preventative engineering.

Requirements

• 5+ years operating MariaDB/MySQL in high-volume production environments, including tuning, replication, and troubleshooting.
• Strong understanding of high-availability patterns, distributed database behavior, and practical failure scenarios.
• Hands-on experience with database proxies or load-balancing layers (HAProxy, ProxySQL, MaxScale, or similar).
• Practical experience with CI/CD, GitOps, and Infrastructure-as-Code workflows (Terraform experience ideal).
• Solid cloud, Linux, and networking fundamentals.
• Experience with containers and orchestration platforms (building container images and managing Kubernetes workloads at scale).
• Strong security instincts around access control, upgrade processes, and safe operational workflows.
• Observability expertise: monitoring, alerting hygiene, and readiness for incident response.
• Strong communication and collaboration skills with the ability to partner with stakeholders, negotiate long-term plans, write formal documentation and tie success to specific metrics and KPIs.
• Nice to have:

- Experience with SRE methodologies such as error budgets, operational reviews, or reliability programs. - Strong scripting or programming ability (Python or Rust preferred) used to build automation and internal tools. - Hands-on experience with GitOps tooling (ArgoCD, GitHub Actions, GitLab CI). - Exposure to multi-region or disaster-recovery designs. - Interest in cryptocurrency or decentralized systems.
