What's New at Tucows

As part of Tucows (NASDAQ:TCX, TSX:TC)—one of the world's largest Internet services companies—Wavelo is backed by outstanding resources and talent. We embrace a people-first philosophy that is rooted in respect, trust, and flexibility. We believe that whatever works for our employees is what works best for us.

The work we do genuinely changes lives. If this sounds exciting, we'd love to hear from you!

We're looking for an experienced Database Reliability Engineer to join our infrastructure team. You'll be a key player in maintaining, supporting, and improving our Postgres infrastructure. Our platform consists of multiple Postgres clusters of varying sizes, as small as two servers and a few gigabytes, to as large as ten servers and multiple terabytes.

We're looking for someone with solid PostgreSQL knowledge who's comfortable owning production incidents, supporting and collaborating with developers, and contributing to infrastructure-as-code.

You'll work closely with other DBAs, SREs, and application teams to ensure our Postgres environment is reliable, scalable, and high-performing.

This is a remote position for applicants in Canada or USA.

• Own, investigate, and resolve production issues related to PostgreSQL — whether they stem from infrastructure or application-layer causes.
• Collaborate with developers to debug and resolve Postgres-related application issues, and improve database performance.
• Maintain and improve our PostgreSQL infrastructure, including performance tuning, replication, backup/restore processes, and upgrades.
• Make infrastructure changes using Terraform and Salt — including configuration changes, deploy new clusters, and expand existing clusters.
• Monitor database health, implement and improve alerts, and contribute to capacity planning.

• 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. Range may vary on a number of factors including, but not limited to: location, experience and qualifications. Tucows believes in a total rewards offering that includes fair compensation and generous benefits. Learn more about Tucows Benefits.
