This is a remote position.

We are seeking two to three experienced Database Administrators (DBAs) to support a major database upgrade project. The successful candidates will play a critical role in planning, executing, and validating the migration of our PostgreSQL and AWS RDS environments, ensuring high availability, minimal downtime, and data integrity throughout the process.

Work will primarily follow Eastern Standard Time business hours, with flexibility required to perform critical upgrade activities during low-traffic windows such as late evenings or weekends.

In addition to core DBA responsibilities, this role requires hands-on experience with Bash scripting, GitHub version control, and automation to support deployment pipelines and operational runbooks.

•       Lead and execute major PostgreSQL and AWS RDS database version upgrades

•       Develop and maintain detailed upgrade plans, rollback procedures, and runbooks

•       Perform pre- and post-upgrade database health checks, validation, and performance benchmarking

•       Monitor, tune, and optimize database performance during and after the migration

•       Collaborate with application, infrastructure, and DevOps teams to coordinate upgrade activities

•       Document all procedures, configurations, and changes in a clear and auditable manner

•       (Role B only) Write and maintain Bash scripts to automate routine DBA tasks and upgrade steps

•       (Role B only) Manage version-controlled scripts, runbooks, and configs using GitHub

Primary working hours align with Eastern Standard Time (EST). Candidates must be available for scheduled maintenance windows — including evenings and weekends — during critical phases of the upgrade project. Advance notice will be provided for all off-hours activities.
