DBA & Bulk Data Management Engineer

Stack

Responsibilities

• ▹Own every database underpinning the platform, from the core BSS/OSS/NOC modules through to the PostgreSQL stores behind different applications
• ▹Maintain interfaces to vendor-managed databases inside HSS, OCS, PCRF, and SMSC nodes
• ▹Ensure mediation pipelines that bring network data into other required systems are reliable, complete, and governed by clear data-handling policies
• ▹Build end-to-end backup, restoration, and disaster-recovery framework for all BSS and network-layer PostgreSQL clusters
• ▹Build performance optimization roadmap covering index strategies, query tuning, table partitioning, and vacuuming schedules
• ▹Build bulk data pipelines for large-scale imports, exports, migrations, and timed purges of subscriber CDRs and event records
• ▹Define data handling, retention, and archival policies aligned with GDPR, operator SLAs, and internal compliance requirements
• ▹Build database monitoring dashboards (Prometheus + Grafana exporters) with alerting for replication lag, lock contention, query performance, and disk saturation
• ▹Write installation and upgrade playbooks for new PostgreSQL instances
• ▹Build a cross-platform data integration layer between BSS mediation and network-element databases
• ▹Conduct schema review and data-architecture advisory for BSS and Workflow engineering teams
• ▹Build a data access control framework: roles, privileges, row-level security, and audit logging
• ▹Write runbooks and a knowledge base covering database operational procedures, DR playbooks, and incident response steps

Requirements

• ▹Strong hands-on PostgreSQL administration: installation, configuration, replication (logical/streaming), upgrade, and vacuum tuning
• ▹Proven backup and restore experience: pg_dump, pg_basebackup, WAL archiving, point-in-time recovery, and DR testing
• ▹Query performance analysis: EXPLAIN/ANALYZE, index design (B-Tree, partial, composite), and schema-level optimization
• ▹Bulk data operations: large COPY/INSERT loads, logical replication for live migrations, and automated purge/archival pipelines
• ▹Data governance: designing and documenting retention, archival, masking, and access-control policies
• ▹Scripting in Python or Bash for automation of backup jobs, health-check scripts, and bulk-load utilities
• ▹Experience with containerized database deployments (Docker / Kubernetes)
• ▹Monitoring: setting up Prometheus postgres_exporter, building Grafana dashboards for database KPIs
• ▹High-availability patterns: replication failover, connection pooling (PgBouncer / Pgpool), read-replica routing
• ▹Ability to work independently across multiple concurrent projects in a distributed team
