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. 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. 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.

We’re primarily a Python shop, using Django for our websites. We also have a few services written in Go and have started to build out our front ends using React. We use Github to host our code, Jenkins (for now) to automate our tests, and right now most of our applications and code live in VMs in a Colo just outside of Toronto. We’re in the process of transitioning to AWS. Other common technologies we use are Postgres (primary DBs), Redis (cache and key/value store), RabbitMQ (messaging broker) and Celery (task queue).

We are currently transitioning from a PHP backend monolith with Backbone.js and React.js, to a service-oriented architecture with micro-services built in Node.js or Go and React components on the frontend.
