Database Architect, PostgreSQL

Job Location (Short): Hyderabad, India

Workplace Type: Hybrid

Req Id: 3454

**Responsibilities**

--------------------

We are seeking an experienced PostgreSQL Architect to design, migrate, and optimize enterprise databases from Oracle and SQL Server to PostgreSQL. The ideal candidate will have strong experience designing high-transaction, multi-tenant PostgreSQL environments and leading complex database migrations with minimal downtime.This role requires a cloud-agnostic mindset. Candidates may have experience with PostgreSQL on any cloud platform or in self-managed environments. They should be able to design solutions that support portability while making informed use of cloud-managed database services where appropriate.

**PostgreSQL Development and Performance**

• Design scalable and reliable PostgreSQL architectures for high-volume transactional workloads, with a cloud-agnostic way
• Define strategies for indexing, partitioning, connection pooling, replication, and query optimization
• Analyze query execution plans and tune database performance, including autovacuum, locking, concurrency, and resource utilization
• Perform capacity planning and establish performance benchmarks for production workloads
• Define database architecture standards, coding guidelines, naming conventions, and technical review processes.

**Database Migration**

• Lead end-to-end migrations from Oracle and/or SQL Server to PostgreSQL, including discovery, assessment, schema conversion, data migration, validation, and cutover
• Assess source databases for compatibility gaps, migration complexity, technical dependencies, and performance risks
• Convert and refactor database objects, including stored procedures, functions, triggers, sequences, views, packages, and custom types
• Translate PL/SQL or T-SQL logic into appropriate PostgreSQL solutions using PL/pgSQL and other suitable approaches
• Define migration strategies, including big-bang, phased, or parallel-run approaches, with rollback plans and downtime requirements
• Work with QA and application teams to perform data reconciliation, functional testing, and performance benchmarking.

**Multi-Tenant Design**

• Design PostgreSQL solutions using appropriate tenant isolation models, such as database-per-tenant, schema-per-tenant, or shared schema with row-level security
• Evaluate each model for security, performance, scalability, operational complexity, and cost
• Establish tenant-aware monitoring, capacity planning, backup, and recovery practices.

**Cloud and Operations**

• Architect PostgreSQL deployments on any cloud platform, including managed PostgreSQL services or self-managed installations on virtual machines or Kubernetes
• Design for portability across cloud environments, while documenting any dependencies on provider-specific services or features
• Define high availability, backup, point-in-time recovery, disaster recovery, and replication strategies based on business requirements
• Partner with Cloud Operations and Security teams on monitoring, patching, access control, auditing, incident response, and cost optimization
• Develop automation and operational runbooks for deployment, migration, validation, backup, and recovery.

**Collaboration and Leadership**

• Collaborate with developers on data access patterns, ORM configuration, transaction handling, and query design
• Document architecture decisions, migration plans, risks, and technical trade-offs
• Mentor DBAs and engineers and help build PostgreSQL capabilities across the team

**Education / Qualifications**

------------------------------

• 8 or more years of experience in database engineering, with at least 4 years of substantial hands-on PostgreSQL experience
• Proven experience designing and supporting PostgreSQL databases for high-volume transactional workloads or large datasets
• Hands-on experience migrating databases from Oracle and/or SQL Server to PostgreSQL
• Strong proficiency in PostgreSQL SQL and PL/pgSQL, with experience reading and converting PL/SQL or T-SQL
• Experience designing and operating multi-tenant database environments
• Deep understanding of query planning, indexing, partitioning, vacuum and autovacuum, locking, concurrency, and connection management
• Experience designing and supporting replication, high availability, backup, restore, and point-in-time recovery
• Experience running PostgreSQL in at least one cloud environment. Experience on any cloud provider is acceptable
• Strong scripting or automation skills using SQL, Bash, or Python
• Experience in Kubernetes and Containers platform
• Strong troubleshooting, documentation, communication, and cross-team collaboration skills.

**Preferred Qualifications**

• Experience with migration tools such as AWS Schema Conversion Tool, AWS DMS, ora2pg, pgloader, or Azure Database Migration Service
• Experience with managed PostgreSQL services such as Amazon Aurora PostgreSQL or RDS for PostgreSQL, Azure Database for PostgreSQL, or Google Cloud SQL for PostgreSQL
• Experience with PostgreSQL backup and recovery using AWS Backup for supported resources, other cloud-native backup services, or PostgreSQL-native utilities
• Experience with self-managed PostgreSQL on Linux virtual machines, containers, or Kubernetes
• Familiarity with connection poolers such as PgBouncer and monitoring tools such as pg\_stat\_statements, Prometheus, or Grafana
• Experience identifying alternatives for Oracle- or SQL Server-specific features during migration
• Experience in regulated environments with database security, auditing, and compliance requirements
• Relevant database or cloud certifications are a plus.

**Core Competencies**

• Architectural judgment: Balances performance, scalability, cost, security, maintainability, and migration risk
• Ownership: Takes responsibility from architecture and migration through production readiness and support
• Collaboration: Works effectively across DBA, Development, QA, Securit
