Job description

Supercharge Your Career as a PostgreSQL Expert at Technoidentity!

Are you ready to solve people challenges that fuel business growth? At Technoidentity, we’re a Data+AI product engineering company building cutting-edge solutions in the FinTech domain for over 13 years—and we’re expanding globally. It’s the perfect time to join our team of tech innovators and leave your mark!

What’s in it for You?

We are seeking a seasoned Senior Database Developer & PostgreSQL Expert with 8-10 years of experience across multiple database systems, with deep hands 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.

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, 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.

What Makes You the Perfect Fit?

• 8-14 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 internals - query planner, vacuum processes, WAL, replication, logical decoding, and high-availability strategies.
• Experience designing PostgreSQL architectures including HA, replication, fault-tolerance, and disaster recovery.
