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.

What you’ll bring:

* Deep, DBA-level knowledge of ClickHouse from running it in production. You should understand how it stores, merges, replicates, and queries data, and be able to explain why a cluster behaves the way it does. Strong SQL is part of this, including optimising 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, and the engine does not have to be ClickHouse.

* You have run and maintained stateful workloads on Kubernetes in production, well beyond the initial deployment.

* Production use of a Kubernetes operator to run databases. Any engine counts, for example CloudNativePG, Zalando Postgres Operator, Altinity, or the official ClickHouse operator.

* 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. You have built monitoring and alerting with any modern observability stack, and you act on early warning signs before they turn into incidents.

* 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.

* You have hands-on experience with cloud infrastructure on any major provider, as opposed to only using a platform that another team runs.

* Clear communication, written and spoken, with engineers and with leadership, whether the subject is architecture, performance, an incident, a risk, or a cost. You should be able to take a problem from investigation to production fix on your own.

Nice to have:

* Hands-on work on the source code of a Kubernetes operator for databases, as a developer or contributor.

* Practical use of AI tools for database observability or for automating routine operational tasks.

* A background in highly regulated environments.

* Any Kubernetes or cloud certifications.

What we offer:

* 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).
