Technical 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

Robust 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
