• 3+ years hands-on experience with PostgreSQL (version 13 and above) in on-prem production environments.
• Strong understanding of SQL performance, query optimization, indexes, and execution plans.
• Good communication skills — especially when explaining database issues to non-DBA teams.
• Experience managing high-availability setups, multi-datacenter setups, replication, backups, and disaster recovery for Postgres.
• Ability to diagnose and resolve incidents involving both database infrastructure and application queries.
• Comfortable collaborating with software engineers to troubleshoot Postgres-related issues in their services.
• Experience working with infrastructure-as-code tools — especially Terraform and Salt (or strong equivalents with willingness to learn).
• A strong sense of ownership and a collaborative mindset.
• Familiarity with Linux systems and command-line tools.

• Experience with monitoring tools (e.g., Prometheus, Grafana, pg_stat_statements).
• Experience with private cloud (OpenStack).
• Exposure to CI/CD pipelines and release automation (GitHub Actions).
• Familiarity with other databases such as MySQL is a bonus, but not required.

The base salary range for this position is $114,120 - $25,000 CAD for Canadian residents or 129,960 to 144,400 USD for US residents. Other countries will differ.
