Reactive Markets; Singapore; On-site; SGD 120,000 - 160,000; Full time

Job summary

Reactive Markets in Singapore is hiring a ClickHouse Engineer to own and operate a multi-datacentre data plant underpinning compliance, billing, and analytics. The estate handles billions of rows daily and requires disciplined production operations.

You will design schema and storage, optimize ingestion and queries, manage capacity, ensure reliability, and collaborate with a senior team across time zones using Kubernetes and Python-based pipelines for real-time analytics.

Responsibilities

• Cluster operations at scale — running, upgrading and evolving a multi-AZ ClickHouse estate on Kubernetes.
• Schema and query engineering — table and sorting-key design, partitioning, materialised views, and query optimisation against multi-terabyte datasets
• Capacity and observability — a measured capacity model, storage tiering and retention, and Grafana monitoring and alerting
• Ingestion and data quality — correctness and completeness gates on the pipelines feeding the plant; reconciliation that proves nothing was dropped
• Workload isolation — keeping ingest, operations, reporting and ad-hoc analytics from treading on each other as read load grows
• AI-assisted operations — modern tooling (including MCP-based AI access to the estate) that lets a small team run a large platform well
