We are hiring a Senior Database Reliability Engineer to join the Infrastructure DBA cell. This is a hands-on production ownership role, not a narrow ticket-processing DBA position. You will keep critical database services reliable, automate repeated work, support engineering teams, and reduce single-person dependency in our PostgreSQL, ClickHouse, MongoDB, and Redis operations.
PostgreSQL is the main requirement. ClickHouse experience is a strong plus, but it is not a day-one blocker. We need a senior engineer with enough database, Linux, automation, and incident-response depth to learn our ClickHouse environment quickly and operate it safely.
Your Responsibilities:
Own production PostgreSQL reliability: HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validation. Improve disaster recovery and operational evidence: tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans. Support the wider database estate: ClickHouse, MongoDB, and Redis. You will troubleshoot incidents, review access and data-safety changes, improve monitoring, and learn the production ClickHouse patterns already in use. Automate DBA workflows with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks for provisioning, grants, backups, restores, health checks, and ownership metadata. Help build DBaaS-style self-service capabilities so engineering teams can request databases, access, credentials, and operational checks with less manual DBA intervention. Improve observability and incident response through Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear communication during production issues.
What Success Looks Like:
PostgreSQL clusters have tested backup and restore paths, useful dashboards, clear ownership, and documented failover procedures.
Repeated DBA tickets become automation or self-service workflows.
ClickHouse operational knowledge is no longer a single-person dependency.
Database incidents have owners, runbooks, evidence, and measurable recovery paths.
Product and engineering teams get database help faster without sacrificing safety, auditability, or reliability.
Why Us?
You will work on real production infrastructure used across products.
You will have a direct impact on reliability, incident response, developer experience, and operational resilience.
You will also work in an AI-assisted engineering culture where automation, documentation, Claude, Codex, and careful human verification are part of the daily operating model.
Requirements
What We Expect From You:
Deep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth.
Strong understanding of PostgreSQL internals and operations: MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testing.
Proven experience with highly available databases and the ability to reason about quorum, split-brain risk, failover, rollback, and recovery.
Strong Linux and infrastructure fundamentals: systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS, firewalls, and root-cause troubleshooting.
Automation skills with Ansible and scripting. Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are strong advantages.
Ability to support more than one database engine. You do not need to be a ClickHouse expert on day one, but you must be ready to learn it quickly and take responsibility for it.
Practical use of AI engineering assistants such as Claude and Codex. We expect you to use them to improve speed and quality, while personally verifying generated SQL, commands, scripts, and operational conclusions.
English - upper-intermediate or higher - to ensure clear communication of progress within the teams.
Nice to Have:
ClickHouse operations: replication, Keeper/ZooKeeper, MergeTree engines, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recovery.
MongoDB replica sets and Percona Backup for MongoDB.
Redis/Sentinel and broker/cache failure modes.
Database observability, SLOs, golden signals, alert tuning, and executable incident runbooks.
Building internal platforms, self-service portals, or DBaaS workflows for engineering teams.
Benefits
A focus on professional development.
Interesting and challenging projects.
Fully remote work with flexible working hours, which allows you to schedule your day and work from any location worldwide.
Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
Compensation for private medical insurance.
Co-working and gym/sports reimbursement.
Budget for education.
The opportunity to receive a reward for the most innovative idea that the company can patent.

CloudLinux is transforming the Linux infrastructure market by ensuring security and stability for over 500,000 servers worldwide. Our products - CloudLinux OS and Imunify360 - are the de facto standard in the hosting industry and Enterprise segment.
We are seeking a visionary engineer to lead the evolution of our data platform. In 2025, we are shifting from classic database administration to an Internal Database-as-a-Service (DBaaS) model. We need a specialist who doesn’t just "configure backups," but designs resilient distributed systems, writes code to automate infrastructure, and transforms databases into a reliable service for product teams.
If you are tired of endless tickets and want to build platforms capable of processing petabytes of data, this role is for you.
Your Challenges & Responsibilities:
DBaaS Architecture:
Design and implement a self-service platform based on
Terraform
and
Ansible
, enabling the deployment of HA clusters (PostgreSQL and ClickHouse, MongoDB, Redis) in a heterogeneous environment (Bare Metal + OpenNebula + Kubernetes + Public Clouds). You will turn infrastructure into a product.
Scaling ClickHouse:
Manage exponentially growing analytics clusters (12+ clusters, tens of terabytes of data). You will tackle sharding, table engine optimization (ReplicatedMergeTree), and building reliable S3 backup pipelines under high load.
Data Platform & Analytics Support:
Maintain and scale the infrastructure for Apache Airflow and Redash. You will ensure the reliability of ETL pipelines and visualization tools, bridging the gap between raw infrastructure and the data analytics team.
Reliability as Code:
Implement SRE practices in data management. Replace manual incident response with automated self-healing mechanisms. Define and implement SLO/SLI for all databases.
Stack Modernization:
Lead the migration process from legacy solutions to modern cloud patterns. Participate in decision-making regarding the implementation of Kubernetes operators for stateful workloads.
Expertise & Mentorship:
Serve as the technical authority for product teams, helping them optimize data schemas and SQL queries for high-load systems.
Our Tech Stack:
Databases
: PostgreSQL 15+ (Patroni, PgBouncer), ClickHouse (Sharded/Replicated), MongoDB, Redis, Kafka
Data & Analytics:
Apache Airflow, Redash (Infrastructure & Integration).
Infrastructure:
Own 3+DC colocation (OpenNebula, Kubernetes, Bare Metal), AWS, Google Cloud, Azure, DO – Hybrid Cloud.
Automation & IaC:
Terraform, Ansible, Python/Go, GitLab, Jenkins, Gerrit.
Observability
: VictoriaMetrics, Grafana, Loki.
Why CloudLinux?
Culture:
A Remote-first company with an "Employees First" principle. We value results, not hours in the office.
Impact:
Your architectural decisions will determine the stability of services used by thousands of companies around the world.
Growth:
We support professional development and pay for training and conferences.
Requirements
What We Expect From You:
AI-Augmented Engineering:
You don't view AI as a replacement for deep technical fundamentals, but as a high-leverage tool. We actively use AI agents (Claude, Codex, Gemini, etc.) to automate boilerplate, analyze complex logs, and speed up research. We expect you to be open to modern workflows and integrate AI into your day-to-day operations, allowing you to focus your brainpower on the true architectural challenges.
Deep PostgreSQL Expertise (5+ years):
You know MVCC internals, understand locking mechanics, can configure Patroni and PgBouncer "with your eyes closed," and have experience with seamless major version upgrades under load.
ClickHouse Mastery:
Experience operating large clusters, understanding ZooKeeper/ClickHouse Keeper, sharding, replication internals, and the ability to diagnose performance issues at the data-part level.
Engineering Mindset (SRE/DevOps):
You hate doing the same task twice by hand. Experience writing complex Terraform modules and Ansible roles is mandatory. Programming skills in
Python
or
Go
for automation are a huge plus.
Hybrid Environment Experience:
You understand the differences between running DBs on Bare Metal vs. Kubernetes vs. Cloud and know how to optimize TCO and disk subsystem performance (NVMe, Network Storage).
