<p><a href="https://fulcrum.lever.co/the-lever-tech-stack-1b30e27d2bb0">Blog Post on our Tech Stack</a></p> <p>Lever uses our own open source MVC framework called Derby that syncs all data via Operational Transformation (the algorithm behind Google Docs). OT is the way we handle concurrency conflicts for any piece of data that is edited at the same time. In addition to real-time sync, OT allows us to provide a smoother UI since we can render updates on the client instantly without waiting for our backend to respond, while still guaranteeing consistency.</p> <p>Lever makes extensive use of AWS, Docker, Node, Mongo, ElasticSearch, and Redis within our infrastructure. We use tools like Hubot to streamline deployments and Grafana to see what’s going on under the hood. In addition to automating all the things, we love to version them too! Our systems are all created using Terraform and Chef, working together to ensure consistency at all costs.</p>

<p>While we use a variety of cutting edge web and mobile technologies at Braze, we're constantly evaluating new tools and encourage everybody to identify the right tool for the job. Additionally, we care little about the language-specific knowledge that you have walking through the door - we're much more interested in finding talented team members who are quick learners with excellent software fundamentals.</p> <p>We build SDKs for Java/Android, Objective-C/iOS, and Javascript/Web. We also build wrapper SDKs for Unity, Xamarin, Cordova, Segment, and React Native. We support sending push notifications to Kindle devices and to Android devices via Baidu.</p> <p>Our dashboard is a Ruby on Rails web application built on top of Redis and MongoDB. We have a data streaming infrastructure built on Kafka. On the frontend, we use a combination of React, Knockout, ES6, and Coffeescript.</p>

GitHub is a Rails 4 application that is composed of a large monolith and a constellation of services written in Ruby, Go, and a handful of other languages. The app and its services are exposed both internally and externally via a GraphQL API. We primarily rely on MySQL for persistent storage, Redis for temporary storage, and, as you might expect, a lot of git repositories. We rely on Kubernetes for container orchestration.
