Whats in it for You?

Senior Database Developer & PostgreSQL Expert

With a strong preference for Oracle to AlloyDB (PostgreSQL) migration expertise, this role blends modernization, advanced PostgreSQL engineering, and cloud-native architecture on Google Cloud Platform (GCP). If you thrive in transforming complex data logic, optimizing performance, and architecting enterprise-grade PostgreSQL systems, this opportunity is built for you.

What Will You Be Doing?

Database Migration & Development

• Lead database migrations from Oracle to PostgreSQL-based platforms like AlloyDB, applying both manual and automated strategies.
• Re-engineer stored procedures, triggers, and packages from PL/SQL to PL/pgSQL.
• Recreate and optimize DB objects (schemas, constraints, views, inIN, GiST, BRIN), and query optimization paths.
• Leverdexes) across target platforms.
• Design PostgreSQL-specific architecture including partitioning strategies, indexing plans (Gage PostgreSQL internals such as vacuum tuning, WAL configuration, and connection management for optimal system performance.

Performance Optimization

• Imlement indexing strategies, query plans, and table partitioning to enhance database performance.
• Use tools like EXPLAIN ANALYZE, pg_stat_statements, and GCP-native monitoring dashboards for tuning.
• Collaborate with DevOps for deployment pipelines and infrastructure-as-code (IaC) best practices.
• Perform deep-dive PostgreSQL performance fine-tuning including buffer cache analysis, autovacuum configuration, and planner optimization.
• Optimize PostgreSQL workloads for high concurrency and large datasets, ensuring stable and predictable performance.

Data Integrity & Validation:

• Build and execute validation scripts for source-to-target comparison.
• Ensure row-level data accuracy, transformation logic fidelity, and zero data loss postmigration.
• Manage large-scale datasets for archival and bulk processing tasks.
• Implement PostgreSQL-native data integrity strategies like constraint management, row-level security (RLS), and trigger-based validations.

Collaboration & Documentation:

• Work with cross-functional teams to translate business logic and legacy workflows to scalable, modern database systems.
• Maintain clear documentation on schema conversions, validation methods, rollback strategies, and change history.
• Create PostgreSQL architecture documents, optimization playbooks, and database best-practice guidelines for engineering teams

What Makes You the Perfect Fit?

• 8+ years of database development experience across Oracle, PostgreSQL, and similar RDBMS platforms.
• Strong expertise in PL/SQL and PL/pgSQL for procedural logic, error handling, and performance tuning.
• Proven track record of large-scale database migration projects (Oracle to PostgreSQL/AlloyDB preferred).
• Proficient in query optimization, indexing, partitioning, and schema normalization.
• Familiar with Agile practices, Git-based version control, and CI/CD workflows.
• Hands-on experience with Google Cloud Platform (GCP) for database hosting,monitoring, and scaling.
• Deep expertise in PostgreSQL internalsquery planner, vacuum processes, WAL, replication, logical decoding, and high-availability strategies.
• Experience designing PostgreSQL architectures including HA, replication, faulttolerance, and disaster recovery.
