DBA & Bulk Data Management Engineer

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 integratio
