Introductory paragraph

We’re Enzyme, a remote-first team of around 15 dedicated professionals spread across North and South America. Our mission is to power innovation in the medical device industry with a robust Quality Management System (QMS) that has established significant industry traction.
Our application’s core, which handles all data writes, is built with Elixir and leverages CQRS/Event Sourcing (via Commanded) to transform events into consumable data for our Ruby on Rails backend. We recently launched a LiveView version of the app, and are in the process of migrating our clients to it. In the meantime most clients still use a previous version built with Ember.js.

Join us if you’re excited to work with a smart, kind, and collaborative team with a shared goal of improving lives through technology. You’ll have the opportunity to grow with us, shaping both our product and the future of Enzyme itself.If you’d like to learn more about our culture, please explore our Employee Handbook.
