<p>We have a service oriented stack deployed on AWS using containers. Most of our backend services are written in Go, with the exception of an NLP/ML service written in Python. Services talk to each other using gRPC.<p> <br> <p>Our web application is served statically from Cloudfront/S3 and is written using React. Is is a Progressive Web App, with a service worker to speed up delivery.</p> <br> <p>We integrate with third party software such as Google Drive, Calendar, Jira, GitHub, Asana, Slack. These areas are some of the most complex parts of our systems. They’re also some of the most important: integrations enable the “magic” of a user coming to Range in the morning and seeing all of their work from the previous day already gathered in one place.</p>

<p>The YC internal software is mostly written in Ruby on Rails and React. We’re hosted on AWS and PostgreSQL. Some experience developing web apps would be helpful, but we don't care if you've used Rails before.</p> <p>Note: Hacker News is written in Lisp, but Hacker News is run by a separate team. While we don't use Lisp anymore in our internal software, we retain the original motivation for it, and welcome Lisp hackers to join us.</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>

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).
