Flow Traders is looking for an experienced Database Administrator (MariaDB/MySQL) in Hong Kong to join our growing global team of in-house database experts. You will be working across global teams on the setup, management and continuous evolution of a global database landscape constituting one of the cornerstones of our operations. This is a unique opportunity to join a leading proprietary trading firm with an entrepreneurial and innovative culture at the heart of its business.  We value quick-witted, creative minds and challenge them to make full use of their capacities.

What You Will Do

• Design, deploy, and manage high-performance database instances optimized for low-latency workloads.
• Optimize query performance, schema design, and storage configuration for InnoDB.
• Build automation and monitoring to ensure database availability, scalability, and performance under extreme load.
• Collaborate closely with traders, quants, and developers to tune data pipelines and application-database interactions.
• Troubleshoot complex issues under pressure, including performance regressions, locks, crashes, and replication inconsistencies.
• Evaluate and occasionally work with other data technologies including SQL Server, ClickHouse, depending on business needs.

What You Will Need to Succeed

• Experience working in global high-uptime, high-throughput environments.
• Hands-on, in-depth experience with MariaDB, especially expert-level understanding of InnoDB internals, tuning, replication, backup strategies, and failure recovery.
• Solid command of SQL and familiarity with stored procedures, triggers, and performance profiling.
• Familiarity with Linux, system-level performance tuning, and resource management.
• Strong scripting skills in Bash, Python, or similar for automation tasks.
• Ability to thrive under pressure in a high-stress, high-performance culture.
• Strong communication skills and the ability to work collaboratively across teams and global offices

Nice to Have

• Exposure to high-frequency trading, capital markets, or real-time analytics.
• Familiarity with one or more of the following:

• Cloud-based MySQL/MariaDB/PostgreSQL services on AWS/GCP
• Clickhouse
• Microsoft SQL Server
• Terraform
• Galera Cluster
• ProxySQL
• Puppet
