About Coalesce

Coalesce is on a mission to make the modern data stack effortless for everyone. Our platform powers data modeling, transformation, catalog, and governance for some of the world's most important analytics teams. Customers rely on Coalesce as the core platform for running their data operations, enabling the discovery and transformation of their data into useful, consistent analytics insights that power their business.

About the Infrastructure Team

We are small and nimble, but mighty and now… growing!  We are a team of DevOps generalists tasked with building and maintaining the cloud platform the Coalesce application runs on.  We all bring various experiences and skill sets to the table, and we appreciate new ideas and diverse viewpoints.  We work to ensure that the platform is scalable, resilient, auditable and reproducible and we do this by embracing Infrastructure as Code (IaC) using Terraform and automation, constantly refining and improving to add value to the business. As a department we’re responsible not only for cloud infrastructure, but also CI/CD used to test and deploy our application, and security compliance + audit in partnership with our Security Team.
