DBA -Performance & Load Testing

DBA Performance & Load Testing This is a highly specialized role requiring deep expertise in database performance engineering, scalability testing, workload analysis, and bottleneck identification within mission-critical transactional systems. Hands-on Performance and Load Testing experience is essential. We are seeking top-tier, senior candidates, not generalists. Familiarity with tools such as k6 (preferred), Locust, Gatling, distributed load generation, and modern observability stacks is expected. The ideal candidate will have extensive experience with MariaDB and MySQL, performance tuning under load, replication optimization, database observability, and database scalability strategies. Mandatory Expectations Hands-on Performance & Load Testing experience is mandatory. Strong experience with MariaDB and MySQL performance engineering. Experience working on high-scale, event-driven transactional platforms. Expertise with k6 (preferred), Locust, Gatling, or comparable load-testing frameworks. Experience supporting distributed load generation and large-scale performance testing programs. Strong familiarity with modern observability stacks including Grafana, Prometheus, Datadog, and Open Telemetry. Proven ability to identify, analyze, and remediate complex database performance bottlenecks. Experience working in cloud-native environments and collaborating within Performance Engineering teams. Must be a senior specialist, not a generalist DBA.Technical Skills 7+ years of experience as a Database Administrator with strong focus on database performance engineering.
