Lead and support Amazon Aurora PostgreSQL environments, focusing on migration from Oracle, database performance tuning, and operational management.
Mactores is the agent-native AWS modernization firm. We ship modernization to production in weeks — data platforms migrated, applications refactored, AI agents running against real data. Our delivery is built on the agent platform built by our team, and executed by forward-deployed engineers who own outcomes end-to-end. Fixed-date commitments. Real production systems. Retired legacy.
We are an AWS Premier Tier Services Partner with the AWS Agentic AI Specialization, seven AWS Consulting Competencies (including Migration and Modernization, Data and Analytics, Machine Learning, and AI Services), and seventeen AWS Service Validations. Our named production customers include Synaptics, Flipboard, Poshmark, Tilia, KlearTrust, and Safaricom.
Most modernization work doesn't ship. Ours does. That's the job.
We are looking for an experienced Senior Database Administrator to lead and support Amazon Aurora PostgreSQL environments as part of an Oracle to PostgreSQL migration program. The role requires deep hands-on expertise in database administration, AWS DMS, performance tuning, security, and post–go-live stabilization in production environments.

- Design, set up, configure, and manage Amazon Aurora PostgreSQL clusters.
- Configure parameters, maintenance windows, monitoring, and scaling strategies.
- Ensure high availability, fault tolerance, and operational readiness.
- Perform user, role, and privilege mapping from Oracle to PostgreSQL.
- Implement least-privilege access, role hierarchies, and security best practices.
- Support audit and compliance requirements.
- Configure, run, monitor, and optimize AWS DMS tasks (Full Load and CDC).
- Troubleshoot DMS latency, data mismatches, and performance issues.
- Tune DMS settings for large-volume and high-throughput workloads.
- Perform server and database performance tuning (CPU, memory, I/O, connections).
- Tune PostgreSQL parameters, autovacuum, indexing, and query behavior.
- Proactively identify and resolve performance bottlenecks.
- Design and implement backup and restore strategies.
- Define and test disaster recovery (DR) and failover procedures.
- Support cross-region replication and recovery drills.
- Lead post–go-live stabilization activities.
- Monitor production workloads and resolve incidents.
- Act as L3 escalation point for database-related production issues.
- Provide operational documentation and handover support.

- Proven expertise in Oracle to PostgreSQL migration support

- Strong knowledge of backup, restore, and DR planning in AWS
- Experience with AWS monitoring tools (CloudWatch, Performance Insights)
- Strong problem-solving and root-cause analysis abilities
- Experience working in production and post–go-live environments
- Ability to work independently as an L3 escalation engineer
- Clear communication and documentation skills|
You will be preferred if
- Familiarity with automation and configuration management tools, such as Ansible, Chef, or Puppet
