CloudLinux is hiring a Senior Database Reliability Engineer (DBRE) & Architect (worldwide remote)

CloudLinux is hiring a Senior Database Reliability Engineer & Architect to lead the strategic evolution of our data platform. You will be instrumental in shifting from classic database administration to an Internal Database-as-a-Service model, designing resilient distributed systems and writing code to automate infrastructure.

What You'll Do

• Design and implement a self-service DBaaS platform using Terraform and Ansible, enabling HA cluster deployment (PostgreSQL, ClickHouse, MongoDB, Redis) across Bare Metal, OpenNebula, Kubernetes, and Public Clouds.
• Manage exponentially growing analytics clusters (12+ clusters, tens of terabytes), tackling sharding, ClickHouse table engine optimization, and building reliable S3 backup pipelines under high load.
• Maintain and scale infrastructure for Apache Airflow and Redash, ensuring the reliability of ETL pipelines and visualization tools.
• Implement SRE practices in data management, replacing manual incident response with automated self-healing and defining SLO/SLI for all databases.
• Lead migrations from legacy solutions to modern cloud patterns and participate in decision-making regarding Kubernetes operators for stateful workloads.
• Serve as the technical authority for product teams, helping them optimize data schemas and SQL queries for high-load systems.

What We're Looking For

• Deep PostgreSQL Expertise (5+ years): Knowledge of MVCC internals, locking mechanics, ability to configure Patroni and PgBouncer, and experience with seamless major version upgrades under load.
• ClickHouse Mastery: Experience operating large clusters, understanding ZooKeeper/ClickHouse Keeper, sharding, replication internals, and diagnosing performance issues at the data-part level.
• Engineering Mindset (SRE/DevOps): Experience writing complex Terraform modules and Ansible roles. Programming skills in Python or Go for automation are a huge plus.
• Hybrid Environment Experience: Understanding the differences between running DBs on Bare Metal vs. Kubernetes vs. Cloud and knowing how to optimize TCO and disk subsystem performance.
• Systems Approach: Ability to see the big picture from network packet to application business logic, with an understanding of security (FIPS, Audit logs) and Disaster Recovery.

Nice to Have

• Experience building an Internal Developer Platform (IDP).
• Experience operating databases in Kubernetes (CloudNativePG, Altinity Operator).
• Experience working in Cloud and Hosting providers on similar services.

Technical 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

Benefits & Compensation

• A focus on professional development.
• Interesting and challenging projects.
• Fully remote work with flexible working hours, 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.
