The posting

The Senior Database Administrator is responsible for the design, implementation, optimization, and support of Experity’s cloud-native database platforms, focusing primarily on Aurora PostgreSQL and MySQL running on AWS RDS.

Responsibilities:

  • Deploy, configure, and manage PostgreSQL and MySQL databases in AWS RDS and Aurora environments.
  • Configure and manage MySQL parameter groups, option groups, automated backups, snapshots, and maintenance windows.
  • Architect and support high availability solutions leveraging clusters, read replicas, Multi-AZ deployments, writer/reader endpoint strategies and read scaling.
  • Monitor and mitigate replication lag across replicas to ensure read consistency and performance.
  • Tune and manage database-specific parameters.
  • Optimize workloads for Aurora storage architecture, including I/O patterns, autovacuum behavior, and checkpoint tuning.
  • Optimize database indexing, query execution plans, and MySQL InnoDB configuration for production workloads
  • Monitor and troubleshoot database performance using AWS CloudWatch, DataDog, and Database-native tools (e.g., pg_stat_statements, EXPLAIN).
  • Analyze and optimize query performance, indexing strategies, and resource utilization.
  • Investigate and resolve complex production issues, including locking, blocking, replication lag, and connection saturation.
  • Implement and manage backup and recovery strategies including point-in-time recovery (PITR), automated snapshots, and cross-region resilience.
  • Partner with engineering teams to improve schema design, query patterns, and database access efficiency.
  • Drive observability best practices, including alerting, logging, and performance metrics across database environments.
  • Optimize cloud database cost and performance, including instance sizing, storage utilization, and workload tuning.
  • Support and contribute to database migrations and modernization efforts.
  • Automate database provisioning and operations using Infrastructure-as-Code and scripting.
  • Participate in incident response, root cause analysis, and continuous improvement processes.
  • Support MySQL version upgrades, patching, and database migrations with minimal downtime.
  • Other duties as assigned.

Education:

  • Bachelor’s degree in Computer Science or related field, or equivalent experience.

Experience:

  • Minimum 5 years of database administration experience, with 3+ years focused on PostgreSQL in high-volume OLTP production environments.
  • 2+ years administering MySQL in production, preferably on AWS RDS.
  • Strong hands-on experience with AWS Aurora PostgreSQL and AWS RDS MySQL.
  • Deep understanding of PostgreSQL internals, including query planner, indexing, vacuuming, WAL, and replication.
  • Strong understanding of MySQL architecture, including InnoDB storage engine, replication, indexing, and query optimization.
  • Proven expertise in database performance tuning and troubleshooting in high-availability, high-throughput environments.
  • Experience supporting systems with significant transaction volume (e.g., 100–200+ TPS) and scaling for continued growth.
  • Experience troubleshooting contention scenarios, including locking, blocking, connection saturation, and long-running transactions.
  • Experience with AWS services including RDS, Aurora, EC2, IAM, VPC, CloudWatch, and S3.
  • Experience with monitoring and observability platforms such as DataDog and CloudWatch.
  • Experience designing and supporting High Availability and Disaster Recovery solutions.
  • Strong understanding of relational database design and data modeling.
  • Experience with automation (Terraform, CloudFormation, or similar) and scripting (Python, Bash, etc.).
  • Experience operating in a production SaaS or high-transaction environment.

Team Member Competencies:

  • Demonstrates ownership and accountability for production systems.
  • Strong problem-solving skills with a proactive approach to identifying and resolving issues.
  • Ability to work cross-functionally with engineering and operations teams.
  • Communicates clearly and effectively in both technical and non-technical contexts.
