The ideal candidate will lead/support end-to-end migration activities including assessment, schema conversion, data migration, application compatibility, performance tuning, and cutover planning., 5+ years of overall database engineering/DBA experience; 3+ years hands-on with Oracle-to-PostgreSQL migration projects (not just theoretical knowledge). Strong command of Oracle (PL/SQL, RMAN, Data Pump, performance tuning) and PostgreSQL (PL/pgSQL, extensions, vacuum internals, replication). Practical experience with migration tools: Ora2Pg, AWS SCT, AWS DMS, EDB Postgres Migration Toolkit, Google DMS, or equivalent. Solid understanding of differences between Oracle and PostgreSQL (sequences, ROWID vs CTID, NVL vs COALESCE, hierarchical queries CONNECT BY vs recursive CTEs, autonomous transactions, packages, etc.). Experience with data validation/reconciliation frameworks to ensure migration accuracy. Familiarity with cloud database services (AWS RDS/Aurora PostgreSQL, Azure, Google Cloud Platform Cloud SQL) is a plus. Scripting skills in Shell, Python for automation of migration tasks. Experience with CI/CD pipelines and version control (Git) for schema/code management. Strong problem-solving skills and ability to work with minimal supervision on complex legacy systems. CONTRACTOR, FULL_TIME, PART_TIME ## Description Candidate should have python coding experience and Oracle to PostgreSQL migration experience., Assess existing Oracle databases (schema, PL/SQL objects, indexes, partitioning, triggers, jobs) to determine migration complexity and approach. Perform schema and object conversion from Oracle to PostgreSQL using tools such as AWS SCT/DMS, Ora2Pg, EDB Migration Toolkit, or custom scripts. Convert PL/SQL procedures, functions, triggers, and packages to PostgreSQL PL/pgSQL, resolving syntax and behavioral differences. Design and execute data migration/validation strategies (full load, incremental/CDC, reconciliation) ensuring zero/minimal data loss. Identify and remediate incompatibilities (data types, sequences, materialized views, partitioning strategies, error handling, connection pooling). Optimize PostgreSQL performance post-migration (indexing strategy, query tuning, vacuum/autovacuum, connection pooling via PgBouncer, partitioning). Collaborate with application teams to update SQL queries, ORM configurations, and connection strings/drivers (JDBC/ODBC/psycopg2). Plan and execute cutover strategy including rollback plans, downtime minimization, and go-live support. ## Related Videos - [Optimizing Discovery: PostgreSQL's Role in Transforming GetYourGuide's Search](https://www.wearedevelopers.com/videos/1647-optimizing-discovery-postgresql-s-role-in-transforming-getyourguide-s-search) - [Kubernetes and Microservices with Multi-Model Databases](https://www.wearedevelopers.com/videos/382-kubernetes-and-microservices-with-multi-model-databases) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Branch your database like your code: How schema changes and pull requests go hand in hand](https://www.wearedevelopers.com/videos/350-branch-your-database-like-your-code-how-schema-changes-and-pull-requests-go-hand-in-hand) - [Fault Tolerance and Consistency at Scale: Harnessing the Power of Distributed SQL Databases](https://www.wearedevelopers.com/videos/1146-fault-tolerance-and-consistency-at-scale-harnessing-the-power-of-distributed-sql-databases) - [Postgres in the Age of AI (and Devin)](https://www.wearedevelopers.com/videos/1042-postgres-in-the-age-of-ai-and-devin) ## Related Articles - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [The Best Job Search Websites of 2025](https://www.wearedevelopers.com/magazine/368-the-best-job-search-websites-of-2025) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story)
