🎯 The Role

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.

✅ Key Responsibilities

• 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.
• Manage exponentially growing analytics clusters, tackling sharding, table engine optimization, and building reliable S3 backup pipelines under high load.
• Maintain and scale the 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 mechanisms.
• Lead the migration process from legacy solutions to modern cloud patterns, participating in decision-making regarding the implementation of 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.

📌 Required Qualifications

• Deep PostgreSQL expertise (5+ years), including MVCC internals, locking mechanics, and experience with Patroni and PgBouncer.
• ClickHouse Mastery, including experience operating large clusters, understanding ZooKeeper/ClickHouse Keeper, sharding, replication internals, and diagnosing performance issues.
• Engineering Mindset (SRE/DevOps), with experience writing complex Terraform modules and Ansible roles, and programming skills in Python or Go for automation.
• Hybrid Environment Experience, understanding the differences between running DBs on Bare Metal vs. Kubernetes vs. Cloud and optimizing TCO and disk subsystem performance.
• Systems Approach, seeing the big picture from the network packet to the application business logic, understanding security (FIPS, Audit logs) and Disaster Recovery.
• English: upper-intermediate or higher - to ensure clear communication of progress within the teams.

⭐ Desirable Experience

• 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.
