About the Role

Tata Consultancy Services is seeking a top-tier, senior Database Administrator specializing in database performance engineering, scalability testing, workload analysis, and bottleneck identification within mission-critical transactional systems. This is a highly specialized role requiring deep expertise in optimizing MariaDB and MySQL environments under heavy load conditions, rather than a generalist DBA position.

What You’ll Do / Key Responsibilities

  • Performance & Load Testing Leadership: Lead database performance and load testing efforts across large-scale transactional platforms, designing and executing stress, endurance, and scalability tests.
  • Query & Index Optimization: Analyze and tune database behavior, optimizing SQL queries, indexes, schema design, and configurations to improve performance.
  • Troubleshooting & Remediation: Investigate lock contention, deadlocks, slow queries, replication delays, and resource bottlenecks.
  • Monitoring & Observability: Monitor database saturation metrics including active connections, query throughput, disk IOPS, CPU/memory utilization, and buffer pool efficiency using modern monitoring tools.
  • Scaling Strategies: Partner with engineering teams to provide recommendations for database scaling, including instance sizing upgrades, read replicas, schema separation, partitioning, and sharding approaches.

Requirements & Qualifications

  • 7+ years of experience as a Database Administrator with a strong focus on database performance engineering.
  • Extensive hands-on experience administering and optimizing MariaDB and MySQL environments.
  • Proven experience supporting Performance & Load Testing initiatives for high-volume transactional systems.
  • Strong expertise with performance testing tools such as k6, Locust, or Gatling.
  • Deep understanding of query optimization, index optimization, execution plan analysis, and replication performance tuning.
  • Strong Linux administration and automation experience.
  • Experience working in cloud-native and Kubernetes-based environments with observability platforms such as Grafana, Prometheus, Datadog, and OpenTelemetry.

Preferred / Bonus Qualifications (if applicable)

  • Preference for familiarity with k6 load-testing frameworks.
  • Strong technical leadership, mentoring, and stakeholder management skills.

Benefits & Perks (if applicable)

  • Competitive salary range of $100,000 – $120,000 per year.
