If this sounds like a team and culture that matches your personal values and motivations, we want to hear from you.
Responsibilities:
Key Responsibilities
Cloud‑Native Database Engineering
-
Architect, deploy, and manage PostgreSQL instances and clusters in cloud environments (AWS/Azure/GCP or managed solutions like RDS, Aurora, Azure Flexible Server, Cloud SQL).
-
Develop cloud‑efficient database schemas, indexing strategies, and storage configurations.
-
Optimize resource utilization (I/O, compute, storage tiers) to balance performance and cost.
Advanced Performance Tuning & Optimization
-
Diagnose and resolve complex performance challenges using query analysis, indexing strategies, and execution plan optimization.
-
Continuously tune PostgreSQL parameters (work_mem, shared_buffers, autovacuum tuning, WAL settings) to support high‑throughput workloads.
-
Analyze pg_stat_activity, pg_stat_statements, and cloud native performance metrics to proactively detect and fix performance issues.
-
Work closely with developers to optimize queries and improve data access patterns.
Archival Strategy & Data Lifecycle Management
-
Define and implement a comprehensive data archival strategy to reduce resource consumption and improve performance.
-
Architect cold storage, tiered storage, or partitioning-based archival solutions (e.g., native partitioning, time-based partition strategies).
-
Automate archival, retention, and purging processes while ensuring compliance and auditability.
-
Ensure archival strategies align with cloud cost optimization and long-term retention needs.
Database Maintenance, Patching, & Upgrades
-
Develop and execute patching, minor version updates, and major upgrade strategies with minimal downtime.
-
Implement blue/green or rolling upgrade patterns where supported.
-
Ensure all PostgreSQL versions adhere to cloud provider support policies and internal governance.
-
Maintain robust upgrade automation (Ansible, Terraform, CI/CD pipelines, or cloud-native tools).
Reliability, Monitoring & Operations
-
Configure and tune monitoring and alerting for performance, replication health, vacuum performance, storage growth, and query latency.
-
Ensure strong HA/DR strategies leveraging built‑in or cloud-native replication and failover mechanisms.
-
Conduct capacity planning and performance forecasting to keep ahead of workload trends.
-
Troubleshoot database incidents and drive root‑cause analysis for performance degradations.
Automation & DevOps Integration
-
Automate provisioning, configuration, tuning, and lifecycle workflows using scripting (Python, Bash) and IaC tooling.
-
Integrate database tasks into DevOps pipelines to support continuous deployment and automated patching.
-
Build internal tools to improve operational consistency and visibility.
Qualifications:
Qualifications
-
5+ years of production PostgreSQL engineering experience, including cloud deployments.
-
Deep expertise in performance tuning, advanced query optimization, and PostgreSQL internals (WAL, MVCC, vacuum processes, query planner).
-
Strong experience with cloud‑managed PostgreSQL platforms such as AWS RDS/Aurora, Azure PostgreSQL, or GCP Cloud SQL. AWS RDS/Aurora is preferred.
-
Hands‑on expertise with replication, failover, vacuum management, and HA strategies.
-
Experience implementing data archival and lifecycle management practices at scale.
-
Proven experience executing patching and major/minor PostgreSQL upgrades.
-
Strong scripting skills in Bash or Python.
-
Solid experience with monitoring tools (pg_stat_statements, Prometheus/Grafana, pganalyze, CloudWatch, Azure Monitor).
-
Candidates must be authorized to work in the U.S. without the need for current or future sponsorship.
