Our Client, a multi-national telecommunications technology is seeking an experienced Site Reliability Engineer (SRE) with hands-on PostgreSQL to join their Data Center Engineering team. This role requires a technically strong and operationally mature engineer who will help design, scale, and maintain the reliability of our client's physical and virtual data center infrastructure. You will be a technical leader responsible for ensuring system uptime, optimizing capacity and performance, and contributing to long-term infrastructure resiliency.
Key Responsibilities:
- Design, implement, and maintain PostgreSQL databases, including schema design, indexing strategies, query optimization, logical/physical replication, hot standby failover, and load balancing.
- Develop and execute backup and recovery strategies, including pg_dump, pg_basebackup, WAL archiving, point-in-time recovery (PITR), and disaster recovery planning.
- Monitor and optimize database performance, resource utilization, and storage growth using pg_stat_statements, EXPLAIN ANALYZE, pg_top, and Prometheus/Grafana dashboards; proactively troubleshoot performance bottlenecks.
- Ensure database security through role-based access control (RBAC), audit logging with pgaudit, and compliance with regulatory standards.
- Implement high availability (HA) and disaster recovery (DR) solutions using Patroni, streaming replication, synchronous/asynchronous replication, and failover orchestration.
- Plan and execute database version upgrades and apply security or performance patches with minimal downtime, ensuring data integrity and compatibility checks.
- Collaborate with application teams, BI developers, and ETL engineers to support data pipelines, optimizing queries, and workflow performance.
- Implement monitoring and alerting solutions using Prometheus, Grafana, Zabbix, or Nagios to track database health, query latency, and resource usage.
- Manage database user accounts, roles, and privileges to enforce security policies and regulatory compliance, including sudo/OS-level permissions for critical operations.
- Conduct capacity planning, workload forecasting, and index/partition tuning to handle anticipated growth and high-concurrency workloads.
- Automate database maintenance tasks using Python, Bash, or Ansible scripts, including schema migrations, routine checks, and patch deployment.
- Document procedures, configurations, operational runbooks, and PostgreSQL best practices for team knowledge sharing.
- Mentor and guide team members on PostgreSQL internals, replication setups, and performance tuning techniques.
- Evaluate and recommend new database tools, extensions (like TimescaleDB, pg_stat_statements), and best practices to improve efficiency, scalability, and resilience.
