The role focuses on platform architecture, high availability, security hardening, and operational excellence across on-premises and cloud-hosted PostgreSQL estates.\nThe ideal candidate will design and maintain robust PostgreSQL infrastructure, lead database migrations from heterogeneous platforms (such as SQL Server or Oracle), and ensure production systems meet stringent performance, availability, and compliance requirements.\nThis role requires deep expertise in PostgreSQL internals, cloud-native database services, and operational automation.\nKey Responsibilities:\nMigration Planning & Platform Architecture:\nArchitect and execute migration strategies for moving SQL Server, Oracle, and other heterogeneous databases to PostgreSQL / Aurora PostgreSQL with minimal downtime.\nDesign target PostgreSQL architectures including instance sizing, storage layout, replication topologies, and high-availability configurations.\nPlan and implement migration cutover strategies in coordination with application, DBA, and platform teams; ensure rollback capabilities are validated.\nEvaluate and recommend migration tooling (AWS DMS, SCT, pg_dump/pg_restore, Bucardo, pglogical) based on workload characteristics and downtime tolerance.\nDatabase Administration & Operations:\nInstall, configure, and manage PostgreSQL instances across development, staging, and production environments (self-managed and AWS RDS/Aurora).\nImplement and manage streaming replication, logical replication, and failover mechanisms (Patroni, repmgr, or Aurora native failover).\nPerform routine maintenance: vacuum tuning, autovacuum optimization, bloat monitoring, index maintenance, and major version upgrades.\nManage backup and disaster recovery strategies using pgBackRest, Barman, WAL archiving, and cross-region snapshot replication.\nPerformance Tuning & Capacity Management:\nMonitor and optimize PostgreSQL performance at the OS and database level: I/O throughput, memory allocation (shared_buffers, work_mem, effective_cache_size), connection pooling (PgBouncer), and lock contention.\nAnalyze slow queries in collaboration with development teams, recommend configuration changes, partitioning strategies, and hardware scaling.\nTune Aurora PostgreSQL-specific parameters and leverage Optimized Reads/Writes where applicable.\nConduct capacity planning and forecast infrastructure needs based on workload growth trends.\nSecurity, Compliance & Governance:\nHarden PostgreSQL environments: enforce SSL/TLS, configure role-based access control (RBAC), implement row-level security (RLS), and manage secrets via AWS Secrets Manager or HashiCorp Vault.\nEnsure compliance with organizational security policies, data retention requirements, and audit mandates (pgAudit, CloudTrail).\nManage encryption at rest and in transit; oversee key rotation procedures.\nReview and approve database changes for security impact; enforce least-privilege access principles.\nAutomation, Monitoring & Incident Response:\nAutomate operational tasks using shell scripts, Python, Ansible, Terraform, or AWS CloudFormation.\nDeploy and maintain monitoring and alerting stacks (CloudWatch, Prometheus/Grafana, Datadog, pg_stat_statements, pgBadger).\nProvide L2/L3 operational support, lead incident response for database outages, replication lag, and performance degradations.\nDevelop and maintain runbooks, operational standards, and disaster recovery playbooks.\nCollaboration & Documentation:\nPartner with development teams to enforce database standards and review schema changes for operational impact.\nMentor internal teams on PostgreSQL administration best practices, migration considerations, and cloud-native database operations.\nDocument architecture decisions, operational procedures, and migration runbooks.\nPreferred Qualifications:\n4+ years of experience in database administration, with at least 3 years focused on PostgreSQL in production environments.\nProven track record in large-scale, heterogeneous migrations (SQL Server → PostgreSQL/Aurora PostgreSQL or similar).\nStrong proficiency in:\nPostgreSQL internals: WAL, MVCC, vacuum mechanics, buffer management, query planner\nHigh availability: streaming replication, logical replication, Patroni, repmgr\nBackup & recovery: pgBackRest, Barman, point-in-time recovery (PITR)\nLinux system administration relevant to PostgreSQL (tuning kernel parameters, filesystems, I/O schedulers)\nAWS RDS/Aurora operations, IAM, VPC networking, security groups, and parameter groups\nExperience with Infrastructure as Code (Terraform, CloudFormation, Ansible) and CI/CD pipelines for database changes.\nFamiliarity with monitoring and observability tools: CloudWatch, Prometheus/Grafana, Datadog, pg_stat_statements, pgBadger.\nNice-to-Have:\nExposure to other database platforms (Oracle, MySQL, SQL Server) for cross-platform migration support.\nExperience with database DevOps practices: GitOps, schema drift detection, automated testing (e.g., tSQLt equivalents, pgTAP).\nKnowledge of Kubernetes operators for PostgreSQL (CloudNativePG, Zalando Postgres Operator).\nAWS Certified Database - Specialty or EDB PostgreSQL professional certifications.\nExperience with pgBouncer connection pooling, pgpool-II, or similar middleware.\nFamiliarity with event streaming integrations (Debezium, Kafka) for CDC and real-time data pipelines.","description_format":"text","description_chars":5509,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Managed
