• Perform root cause analysis and implement long term corrective actions. 

• Maintain backup, restore, and disaster recovery strategies for both Postgres and OpenSearch. 

• Support automation of administrative tasks using InfrastructureasCode (Terraform, CloudFormation) and scripting tools. 

Security & Compliance 

• Implement and maintain IAM policies, encryption at rest/in transit, security groups, and audit logging. 

• Ensure database and cluster configurations meet organizational security standards and regulatory requirements. 

Backup & Restore 

• Define Recovery options (RPO/RTO) and setup appropriate backup strategy. 

• Create plans for backup service management including schedules and disaster recovery options. 

• Implement procedures to restore operations for point-in-time-recovery (PITR) and disaster recovery. 

Collaboration & Communication 

• Work closely with application teams, cloud architects, DevOps engineers, and data stakeholders to support existing systems and plan new capabilities. 

• Provide guidance on database best practices and mentor junior engineers. 

Required Qualifications 

• 5+ years of hands-on experience with PostgreSQL, including advanced SQL, performance tuning, query planning, and replication. 

• 3+ years of experience with Amazon RDS (Postgres) in production environments. 

• 2+ years of experience managing and tuning Amazon OpenSearch clusters. 

• Strong understanding of AWS services including EC2, IAM, VPC networking, S3, CloudWatch, Lambda, and KMS. 

• Experience with Terraform, CloudFormation, or other IaC tools. 

• Proficiency with scripting languages (Python, Bash) for automation and diagnostics. 

• Solid understanding of distributed systems, search indexing, and data lifecycle management. 

Preferred Qualifications
