Description
About the Role
We are building a multi-site platform that orchestrates telecoms services for mobile operators across different regions, with additional network nodes in other regions. As our DBA & Bulk Data Management Engineer you will own every database that underpins this platform from the core BSS/OSS/NOC modules through to the PostgreSQL stores that sit behind our different applications.
You will also extend your ownership into the network control layer, maintaining interfaces to vendor-managed databases inside HSS, OCS, PCRF, and SMSC nodes, and ensuring the mediation pipelines that bring network data into the other required system are reliable, complete, and governed by clear data-handling policies.
This role spans three disciplines: hands-on database engineering (installation, tuning, backup/restore, high availability), bulk data management (large-scale loads, migrations, exports, purges), and data governance (designing and enforcing retention, archival, and compliance policies). You will be a senior individual contributor and the go-to expert for all database topics across the entire BSS and NOC stack.
What You Will Build
End-to-end backup, restoration, and disaster-recovery framework for all BSS and network-layer PostgreSQL clusters.
Performance optimization roadmap covering index strategies, query tuning, table partitioning, and vacuuming schedules for high-throughput subscription and charging data.
Bulk data pipelines for large-scale imports, exports, migrations, and timed purges of subscriber CDRs and event records.
Data handling, retention, and archival policies aligned with GDPR, operator SLAs, and internal compliance requirements.
Database monitoring dashboards (Prometheus + Grafana exporters) with alerting for replication lag, lock contention, query performance, and disk saturation.
Installation and upgrade playbooks for new PostgreSQL instances as the platform scales into additional markets or modules.
Cross-platform data integration layer between BSS mediation and network-element databases (HSS, OCS, PCRF, SMSC, PGW).
Schema review and data-architecture advisory process for BSS and Workflow engineering teams.
Data access control framework: roles, privileges, row-level security, and audit logging across all database tiers.
Runbooks and knowledge base covering all database operational procedures, DR playbooks, and incident response steps. Requirements
Must Have
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 optimisation
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, async-first team.
Multi-datacenter replication and active-passive failover between geographically distributed clusters Strong Advantage
Experience with telecoms BSS/OSS platforms (billing, subscription management, or mediation systems)
Familiarity with network-element databases: HSS (HLR), OCS, PCRF, SMSC, or PGW data models
Data compliance experience (GDPR subscriber data, CDR retention regulations in EU jurisdictions) Nice to Have
Exposure to mediation layer data formats (ASN.1, IPDR, Diameter AVPs)
Experience with BI or reporting extracts from operational BSS databases About Webbing
