📋 Description

• Production PostgreSQL infrastructure across the full lifecycle: architecture, deployment, replication, monitoring, performance tuning, backup/recovery, and capacity planning • Streaming replication and high-availability configurations that meet the uptime expectations of a regulated financial exchange • Query and system-level performance analysis—diagnosing slow queries, optimizing execution plans, tuning shared_buffers, work_mem, and autovacuum, not just reading pg_stat output but knowing what to do about it • Backup and disaster recovery strategy using tools like Barman, including point-in-time recovery testing and validation • Data architecture evolution: modernizing data warehouse and reporting infrastructure, building ETL pipelines, and designing data flows that scale with the business • Data services across the organization: test data management, data obfuscation, data modeling, and supporting data needs for development, QA, and business teams • Operational support including on-call rotation for after-hours production database emergencies

🎯 Requirements

• 5+ years hands-on PostgreSQL administration in production environments—not just dev/test, not just managed RDS • Deep understanding of PostgreSQL internals: WAL mechanics, MVCC, vacuum processing, the query planner and optimizer, connection handling, and lock management • Proven experience with physical and logical replication: setup, monitoring, failover, and troubleshooting split-brain scenarios • Strong SQL performance tuning skills: reading EXPLAIN ANALYZE output, identifying indexing strategies, understanding join algorithms, and resolving locking contention • Solid Linux systems administration (we run Ubuntu)—comfortable with systemd, filesystem performance, memory management, and networking fundamentals • Experience with backup/recovery tools (Barman, pgBackRest, or equivalent) and tested disaster recovery procedures • Experience building and maintaining ETL pipelines and data transformation processes • Ability to work autonomously in a small team where you’re expected to own problems from identification through resolution • Bachelor’s degree in Computer Science, Information Systems, Mathematics, or a related field
