  • Technical Execution: Perform data migrations using tools like AWS SCT/DMS, Ora2Pg, or pgloader, ensuring data integrity.
  • Performance Optimization: Tune PostgreSQL performance, including indexing, query optimization, and handling differences in storage engines.
  • Troubleshooting & Support: Resolve complex data type mismatches, handle replication issues, and provide troubleshooting during and after migration.
Required Technical Skills
  • Oracle Expertise: Proficient in Oracle Database Administration, PL/SQL, and SQL performance tuning.
  • PostgreSQL Proficiency: Strong knowledge of PostgreSQL internals, PL/pgSQL, and configuration.
  • Migration Tools: Experience with migration tools such as AWS Schema Conversion Tool (SCT), AWS Database Migration Service (DMS), or Ora2Pg.
  • Cloud Platforms: Knowledge of AWS (RDS/Aurora) or Azure.
  • Scripting: Proficiency in Python, Bash, or Perl for automation.
Required Experience & Education
  • 10+ years of hands-on experience in Oracle Database Administration, with 3+ years specifically in Oracle-to-PostgreSQL migration.
Key Skills for Success
  • Understanding of microservices architecture.
  • Database security best practices.
  • Excellent communication and stakeholder management skills.
