About the Role
We are looking for an experienced MySQL Database Administrator (DBA) with strong hands-on experience in AWS RDS for MySQL to manage, optimize, secure, and maintain production database environments.
The ideal candidate should have practical experience managing high-availability MySQL databases, troubleshooting performance issues, optimizing complex queries, implementing backup and disaster recovery strategies, and administering databases hosted on AWS.
You will work closely with application developers, DevOps engineers, and infrastructure teams to ensure our databases remain secure, highly available, scalable, and performant.
Key Responsibilities
- Manage and administer MySQL databases across development, staging, and production environments.

- AWS Performance Insights / Database Insights
- CloudWatch metrics and logs
- Optimize indexes, database schemas, queries, and table structures.
- Configure and manage RDS Multi-AZ deployments for high availability.
- Manage Read Replicas and replication-related issues.
- Plan and execute database scaling, including instance upgrades and storage optimization.
- Implement and maintain automated backups, manual snapshots, point-in-time recovery, and disaster recovery procedures.
- Perform database restoration and periodically test backup recovery procedures.
- Handle MySQL version upgrades and AWS RDS maintenance activities.
- Manage database users, roles, privileges, and access controls.
- Implement database security best practices, including encryption, SSL/TLS, IAM integration where applicable, and least-privilege access.
- Work with AWS VPC, Security Groups, IAM, KMS, CloudWatch, Secrets Manager, and other services related to RDS security and monitoring.
- Troubleshoot database connectivity, locking, deadlocks, connection exhaustion, replication lag, and application performance issues.
- Monitor and optimize database storage and infrastructure costs.
- Support database migration from on-premise/VM MySQL to AWS RDS and between RDS environments.
- Assist developers with database design, indexing strategies, stored procedures, queries, and performance improvements.
- Establish database monitoring, alerting, maintenance, and capacity-planning processes.
- Maintain database documentation, SOPs, backup policies, and disaster recovery procedures.
- Participate in production incident troubleshooting and root-cause analysis.

- Experience with AWS CloudWatch and database performance monitoring.
- Understanding of AWS networking concepts such as VPC, subnets, security groups, and private database connectivity.
- Experience with database security, user permissions, encryption, and auditing.
- Experience handling production database incidents and performance bottlenecks.
- Good understanding of High Availability and Disaster Recovery (HA/DR) concepts.

Experience
2–6 years of relevant experience in MySQL Database Administration, with hands-on experience managing AWS RDS MySQL production environments.
What We Are Looking For
We are specifically looking for a hands-on DBA, not someone with only theoretical or basic SQL knowledge.
The candidate should be comfortable independently investigating issues such as:
- Why a MySQL RDS instance suddenly reaches 90–100% CPU
- Why an application query that previously took 200 ms now takes several seconds
- How to identify missing or inefficient indexes
- How to troubleshoot deadlocks and locking issues
- How to handle too many database connections
- How to safely restore a production database
- How to minimize downtime during database migration or upgrades
- How to design backup and disaster recovery strategies
- How and when to use Multi-AZ and Read Replicas
- How to improve RDS performance without unnecessarily increasing AWS infrastructure costs
