PostgreSQL (limited footprint) support: Provide basic administration and operational support for a small number of PostgreSQL databases (monitoring, backups/restore validation, user/access support, and troubleshooting), escalating complex tuning or architecture work as appropriate.
Index maintenance and historical data purging: Implement and tune index/Statistics maintenance aligned to workload and maintenance windows; design and execute archival and purge routines for historical data in accordance with retention requirements.
SQL Server Agent jobs upkeep and maintenance: Create, schedule, document, and maintain SQL Server Agent jobs (ETL, maintenance, reporting, and application jobs); investigate failures, reduce noise, and ensure alerting routes to the right teams.
Monitoring and on-call support: Maintain SQL monitoring/alerting for performance, availability, and capacity; participate in an on-call rotation, execute incident runbooks, and drive post-incident corrective actions.

Space maintenance and capacity forecasting: Monitor database and file growth; manage file sizing and storage layout; provide regular capacity forecasts and coordinate storage expansions to avoid outages.
Weekly reporting on operational KPIs: Produce and publish weekly operational KPI reporting (availability, job success rates, backup compliance, patch compliance, capacity, and key incident trends) with clear follow-ups and risk callouts.
