[Hiring] Senior Database Administrator @Tabby

Role Description

We’re looking for a Senior Database Administrator to join our Infrastructure team. You’ll work on high-impact projects in a high-growth environment, alongside a world-class remote engineering team spread across 20+ countries.

Key Responsibilities:

• Own the reliability and performance of our production ClickHouse clusters, whether self-hosted on Kubernetes or running on managed ClickHouse services.
• Design a standard architecture and tooling that let us grow to dozens of multi-node clusters without the operational work growing at the same pace.
• Manage the whole cluster lifecycle as code: provisioning, configuration, scaling, upgrades, and migrations.
• Build monitoring and alerting that catch problems before users notice them.
• Own backups and disaster recovery, and test restores regularly.
• Keep clusters secure by default.
• Plan capacity and keep infrastructure costs under control.
• Be the go-to person on ClickHouse for developers, DevOps engineers, other DBAs, and engineering leadership, from schema design and data ingestion to query performance.
• Handle routine database requests and automate as many of them as you can.
• Step in during rare production emergencies, including outside business hours. Afterwards, lead the root-cause analysis on the database side and contribute to the postmortem.
• Keep documentation and runbooks up to date, and share what you know with the team.

Qualifications

• Deep, DBA-level knowledge of ClickHouse from running it in production.
• Strong SQL skills, including optimizing complex analytical queries and reviewing schema design.
• Ability to design architecture and automation that holds up across dozens of multi-node clusters.
• Experience running a large fleet of databases (dozens or hundreds of instances) is a strong advantage.
• Experience running and maintaining stateful workloads on Kubernetes in production.
• Production use of a Kubernetes operator to run databases.
• Experience with version upgrades, backup and restore, and migrating large datasets between clusters or regions with zero or minimal downtime.
• Strong troubleshooting skills across the whole stack, from queries and schema design down to Kubernetes, Linux, storage, and networking.
• A proactive approach to database health.
• Database security in practice: encryption in transit and at rest, access control, and secrets management.
• Infrastructure as code with any mainstream tool, plus at least one programming or scripting language for automation.
• Hands-on experience with cloud infrastructure on any major provider.
• Clear communication, written and spoken, with engineers and with leadership.

Requirements

• Hands-on work on the source code of a Kubernetes operator for databases, as a developer or contributor (nice to have).
• Practical use of AI tools for database observability or for automating routine operational tasks (nice to have).
• A background in highly regulated environments (nice to have).
• Any Kubernetes or cloud certifications (nice to have).

Benefits

• Full-time B2B contract.
• Fully remote setup.
• Up to 20% tax allowance.
• 22 paid leave days annually.
• Stock options (ESOP) in a fast-scaling, pre-IPO company.
• Flexi benefits you can use for wellness, travel, or learning.
• Work alongside a high-performing, international engineering team in a global fintech unicorn.
• Relocation support is available to our hubs in Armenia, Georgia, Serbia, Portugal, Poland, and Spain, including flights, temporary accommodation, and legal setup (if needed).
