Database Administrator

Job Description:

Responsibilities

• Design, deploy, and operate PostgreSQL platforms optimized for microservices running on Kubernetes, ensuring scalability, isolation, and resilience
• Architect and manage Azure PostgreSQL Flexible Server and Hyperscale (Citus) for high availability, disaster recovery, and global scale
• Define database design patterns for microservices, including database-per-service, shared services, read replicas, and event-driven data flows
• Partner with engineering teams to ensure PostgreSQL supports CI/CD pipelines, rolling deployments, and zero-downtime releases
• Lead performance tuning and capacity planning across compute, storage, IOPS, memory, and network layers
• Troubleshoot advanced PostgreSQL internals including autovacuum, WAL, MVCC, locking, query planner behavior, and background processes
• Design distributed data architectures using replication, logical decoding, sharding, and multi-region topologies
• Support PostgreSQL connectivity patterns for Kubernetes workloads such as connection pooling, PgBouncer, sidecars, and service mesh integrations
• Lead and execute cloud migrations and modernization initiatives from on-prem or legacy platforms to cloud-native PostgreSQL
• Implement enterprise-grade security and compliance controls including Azure AD integration, encryption at rest and in transit, Private Link, and customer-managed keys
