• Orchestration: Kubernetes (EKS), Terraform, Ansible and on-prem.

Key Responsibilities

• Multi-Engine Management: Administer a hybrid database environment, ensuring seamless data flow between PostgreSQL (Live Trading) and ClickHouse/Snowflake (Analytics).
• Data Movement & ETL: Own the reliability of CDC pipelines that stream data from production Postgres instances into the analytical layer.
• Schema Evolution: Manage schema changes across different engines, ensuring that transactional data models translate effectively into columnar formats for analytics.
• Monitoring & Cost Governance: Implement unified observability for the entire stack. Specifically, monitor Snowflake credit usage and ClickHouse resource utilisation to ensure peak ROI.
• Automation: Use Python, Bash and/or Ansible to automate routine maintenance tasks, deployments and monitoring services.

Technical Requirements & Experience

• Expert-level knowledge of **PostgreSQL** (Performance tuning, vacuuming, indexing).
• Hands-on experience with **ClickHouse** (managing clusters, MergeTree engines, and tuning for high-concurrency).
• Proficiency in **Snowflake** administration (RBAC, Warehouse sizing, Snowpipe, and Task management).
• Experience with AWS (specifically RDS and Aurora).
• Proficiency in Linux/Unix administration and shell scripting.
• Knowledge of monitoring tools (e.g., Prometheus, Grafana, CloudWatch).
• Knowledge of the betting or financial trading industry.
• Relevant certifications (AWS Certified Database, Postgres Professional).
