DBA & Bulk Data Management Engineer

Role Description

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)
• 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.

Qualifications

• 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

Requirements

• 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)

Benefits

• Fully remote
• An exciting and challenging greenfield platform with great skill and knowledge development opportunities
• The opportunity to join a team of highly professional specialists in an international environment
• The opportunity for professional development within a reputable international innovative and growing company
