You will drive scaling and optimization initiatives as part of the Platform Engineering squad to keep databases fast, durable, and cost-efficient as trading data grows.

You will work with MySQL/PostgreSQL at scale, build data archiving pipelines to cold storage, and implement automated

Qualifications

• 4–6 years of professional engineering experience, with at least 2 years in database-focused infrastructure work at moderate-to-high scale.
• Strong expertise in MySQL and PostgreSQL—EXPLAIN plan analysis, index design, partitioning, sharding, and replication setup—on 100M+ row tables.
• Experience building data archiving pipelines to cold storage (S3/Parquet/Athena/Glacier) while keeping records queryable.
• Proficient with AWS managed database services—RDS and Aurora—including provisioning, read replicas, parameter tuning, and monitoring; Aurora Global Database is a plus.
• Hands-on with Redis/ElastiCache—cache invalidation patterns, TTL hygiene, hit-rate monitoring, and incident diagnosis.
• Automation of archival, maintenance, and diagnostic work using Python and/or Bash.
• Familiar with monitoring and observability tooling (Prometheus, Grafana, Datadog) for slow-query alerting and dashboards.
• Knowledge of multi-AZ and cross-region DR architectures, backup strategies, and failover triggers (RTO/RPO < 5 minutes).
• Ability to write Terraform or CloudFormation to provision data resources in a version-controlled, reproducible way.
• Ability to write and debug stored procedures and dynamic partitioning logic for automation.
• Evidence-driven approach to optimization, with before/after data validation.
• Strong communication skills to collaborate with product squads and explain data constraints.

Responsibilities

• Execute database optimization and scaling initiatives—partitioning, sharding, replication configurations, and slow-query fixes.
• Own performance diagnostics on high-volume tables—EXPLAIN plans, index tuning, cache analysis, and replication lag.
• Build and maintain data archiving pipelines to move historical data to cold storage while preserving query access.
• Implement and maintain data lifecycle automation—TTL policies, archival jobs, partition rotation, and retention enforcement.
• Conduct regular performance profiling across the data tier and implement measurable fixes.
• Support load testing and capacity planning for the data layer to prevent production issues during growth.
• Implement and maintain data-tier BC/DR infrastructure with multi-AZ deployments and cross-region replication.
