The ideal candidate will be skilled in leveraging Amazon RDS for Oracle and AWS Database Migration Service (DMS) to ensure high availability, security, and performance of enterprise databases.

Responsibilities

  • Provisioning & Configuration : Create, configure, and manage Oracle RDS instances, including instance sizing, storage, networking (VPC, subnets, security groups), and parameter groups.
  • Performance Optimization : Monitor and tune database performance using CloudWatch, Performance Insights, and query analysis. Implement indexing, SQL tuning, and caching strategies to optimize workloads.
  • High Availability & DR : Design and implement HA and disaster recovery solutions, including Multi-AZ deployments, automated backups, snapshots, and failover strategies.
  • Security & Compliance : Enforce security best practices by managing access controls, database users, roles, and encryption with AWS KMS and IAM policies.
  • Monitoring & Alerting : Configure CloudWatch dashboards, alarms, and notifications for proactive health monitoring.
  • Maintenance & Upgrades : Perform patching, version upgrades, and routine maintenance tasks to ensure reliability and compliance.

Database Migration

  • Migration Planning : Develop and execute strategies for migrating on-premises Oracle databases (or other engines) to AWS RDS. Use DMS Fleet Advisor for readiness assessments.
  • Replication & Data Movement : Configure and monitor AWS DMS tasks for full load migrations and ongoing CDC (Change Data Capture).
  • Troubleshooting & Validation : Diagnose migration issues (connectivity, data validation, performance bottlenecks) and ensure data integrity.
  • Post-Migration Support : Optimize and support databases after cutover to ensure stability and efficiency.

    • Requirements

  • Clearance : Top Secret security clearance fully adjudicated.
  • Bachelor's degree in Computer Science, Information Systems, or a related field
  • Oracle Expertise : Minimum 5+ years of hands-on experience in Oracle database administration, architecture, backup / recovery, and performance tuning.
  • Certifications : CompTIA Security+
  • AWS Experience : At least 3+ years of experience with AWS RDS for Oracle, AWS DMS, and SCT; strong knowledge of core services (EC2, S3, IAM, CloudWatch, CloudFormation / Terraform).
  • Migration Skills : 3+ years of demonstrated success migrating enterprise-scale Oracle databases to AWS cloud environments.
  • Automation & Scripting : 3-5 years of proficiency with scripting languages (SQL / PL / SQL, Python, Bash, or PowerShell) for automation and operational efficiency.
  • Soft Skills : Strong analytical problem-solving ability, excellent communication, and a collaborative mindset for working across teams.

    • Preferred Qualifications

  • AWS Certified Database - Specialty or equivalent certifications preferred.
  • Exposure to DevOps practices and CI / CD pipelines for database changes.
  • Knowledge of hybrid cloud architectures and integrating on-premises systems with AWS.
  • Familiarity with compliance frameworks (FedRAMP, CMMC, SOC 2, etc.) relevant to government and regulated industries.

    • iWorks Corporation is an Equal Employment Opportunity / Affirmative Action Employer. We evaluate qualified applicants without regard to race, color, religion, sex, national origin, disability, Veteran status, sexual orientation, or other protected characteristic.
