At Technoidentity, we’re a Data + AI product engineering company delivering scalable, modern enterprise solutions.

We are seeking a seasoned Senior Database Developer & PostgreSQL Expert with 8–10 years of experience across multiple database systems, with deep hands-on expertise in PostgreSQL internals, performance tuning, advanced indexing, and enterprise data architecture. 

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. 

Requirements

Key Responsibilities 

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, indexes) across target platforms. 
• Design PostgreSQL-specific architecture including partitioning strategies, indexing plans (GIN, GiST, BRIN), and query optimization paths. 
• Leverage PostgreSQL internals such as vacuum tuning, WAL configuration, and connection management for optimal system performance. 

Performance Optimization 

• Implement 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 post-migration. 
• 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. 

Ideal Candidate Profile 

Experience & Skills 

• 4–10 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.
