InVision SaaS Tech Stack

The Invision design collaboration tool has over 3 million users at companies like Airbnb, Disney, and Nike. InVision SaaS primarily uses Golang, NodeJS, Javascript, Angular, React as well as Ruby, Objective-C (the information is from the official Github's account, their engineering blog, employee's profiles on LinkedIn, and jobs' requirements).

Among requirements - "solid professional experience in one of the following backend languages: Java, Ruby, Python, PHP".

InVision is also looking for a Senior Engineering Manager who's familiar with the technologies "range from single-page Javascript applications to backend API servers to iOS and Android mobile applications", a Lead Full Stack JavaScript Engineer, who has a "strong proficiency in vanilla Javascript — you don’t need a framework to get things done", a Senior Software Engineer with "3+ years of experience designing and building native mobile applications in Android (Java and/or Kotlin)", and a Software Engineering Manager who "will get to work with the latest tech, including WebGL, and Kubernetes". 

According to Joshua Siok, a Principal Software Engineer at InVisionApp Inc, he has "contributed to almost every aspect of our primary application as well as several NodeJS services. I daily code in languages such as ColdFusion, JavaScript (AngularJS, jQuery, NodeJS), CSS (LESS), and T-SQL".

According to Boaz Ruck, a Software Engineer at InVisionApp Inc, he has "automated a Nodejs data-migrator as multiple Kubernete's jobs" and is "working on a new data-migrator (Golang) designed to support private cloud and a micro-service architecture".

The Basecamp project management tool helped over 285,000 companies in 2013 alone. Ruby on Rails is the heart and soul of Basecamp. David Heinemeier Hansson, Basecamp CTO, the creator of Ruby on Rails web framework, shared a job opportunity for a Rails programmer: "As an experienced Rails developer, you should be intimately familiar with the framework, with Ruby, and with the stables of full-stack web development: HTTP, JavaScript, CSS, HTML, SQL. It’s a bonus if you’re broadly familiar with other languages as well — we write our iOS app in Swift, our Android app in Kotlin, and have tooling written in Go — but your main work will be Ruby".
