The ideal candidate will have strong experience with MySQL upgrades, AWS RDS and
Aurora, database migration methods, high availability, disaster recovery, performance
tuning, and production support. Exposure to MongoDB, Amazon Aurora PostgreSQL, and
regulated financial-services platforms is highly preferred.
Key Responsibilities

migrations, for large production databases.
• Design upgrade and migration strategies for databases ranging from hundreds of

application dependencies.
• Create upgrade runbooks, rollback plans, validation checklists, risk assessments,
implementation plans, and stakeholder communication plans.
• Conduct pre- and post-upgrade validation, including row counts, checksums,
reconciliation queries, performance benchmarking, and application testing.
• Coordinate production upgrade and migration activities with application,
infrastructure, cloud, security, DevOps, QA, compliance, and business teams.

issues, locking, deadlocks, and application connectivity problems.
• Manage cutover planning, release windows, freeze periods, rollback decisions,
post-migration monitoring, and production hypercare.

MySQL, Amazon Aurora MySQL, Aurora PostgreSQL, EC2-hosted databases, and
AWS Database Migration Service.
• Manage Multi-AZ deployments, read replicas, snapshots, automated backups,

restores, indexing, performance, upgrades, migrations, monitoring, and security
practices.
• Administer Aurora PostgreSQL clusters and support PostgreSQL upgrades, failover,
backups, monitoring, performance analysis, replication, autovacuum, indexing,
partitioning, and query optimization.
Performance, Availability, and Operations
• Monitor and tune MySQL performance in high-volume transaction environments
using slow query analysis, execution plans, indexing, partitioning, configuration
tuning, and workload analysis.

operational health checks, monitoring, alerting, and capacity planning.
• Support asynchronous, semi-synchronous, GTID-based, and read-replica

production escalations.
• Support databases for digital lending, loan origination, loan servicing, payments,
collections, credit decisioning, customer communications, and other financial-
