Position: Senior Database Platform & Performance Engineer

Experience: 47 years (hands-on Postgres in production)

Educational Qualifications

• Bachelor's degree in Computer Science, Information Technology, or a related field
• A higher qualification (Master's degree) in a relevant technical discipline is a plus

Required Skills & Qualifications

• Minimum 3+ years of experience managing PostgreSQL in production environments
• Strong expertise in query optimization, indexing, partitioning, and database tuning
• Experience with AWS RDS (PostgreSQL)
• Proven ability to execute zero or low-downtime schema changes and large-table migrations
• Solid knowledge of security practices RLS, RBAC, etc.
• Added advantage if any other database technology is known

Key Responsibilities

1. PostgreSQL Performance & Reliability

• Diagnose and optimize query execution plans, indexing, and partitioning for large-scale workloads
• Tune VACUUM/autovacuum behavior, connection pooling (PgBouncer), and key configuration parameters (work_mem, shared_buffers, effective_cache_size)
• Implement high availability (HA) and disaster recovery (DR) using synchronous/asynchronous replication and PITR with pgBackRest
• Plan and execute large-table migrations, blue/green upgrades, and schema changes with minimal downtime

2. Database Platform Engineering

• Design and evolve the Postgres platform across compute environments (managed services such as AWS RDS, EC2, Fargate)
• Drive sharding or tenant-partitioning strategies as needed for scale and isolation

3. Observability & Instrumentation

• Enable deep visibility using pg_stat_statements, auto_explain, query sampling/profiling, and end-to-end tracing
• Build actionable Grafana/CloudWatch dashboards and alerting pipelines for query latency, throughput, and replication lag SLOs

4. Security & Compliance

• Implement and maintain robust access control models (RLS/ABAC/RBAC)

5. Schema & SQL Design Partnership

• Collaborate with application engineers on data modeling, schema evolution, and performance-aware API patterns
• Review and guide database migrations (Liquibase or similar) to ensure efficiency and safety

6. Incident Response & Reliability Operations

• Lead Sev-1/Sev-2 database incidents end-to-end: detection, mitigation, RCA, and long-term hardening
• Define and track SLOs for latency, throughput, and uptime across regions

7. Mentorship & Knowledge Sharing

• Conduct SQL performance clinics and internal workshops to upskill developers
• Author and maintain documentation, runbooks, and best-practice guides to reduce key-person risk

8. Roadmapping & Continuous Improvement

• Evaluate and adopt extensions (e.g., pg_partman, pg_cron, pg_repack) and new Postgres versions
• Lead blue/green or rolling upgrade strategies for databases and supporting services
• Partner with product and infra teams to align capacity planning and technology evolution with business growth
