Staff Product Infrastructure Engineer

About Hubs and Hubs Cloud

Hubs is a virtual communications platform that allows groups of people to meet, work or play together in a web-based, 3D environment, embodied in avatars, with access to a rich set of tools and media. At its core, Hubs consists of a set of real time services that use conventional web application server technologies, websockets and WebRTC for voice and video communication. Our stack runs on AWS, using a combination of infrastructure tools including Terraform, Ansible, and Chef Habitat. Primary services are built on top of the Erlang VM (via Elixir), Node.js and PostgreSQL.

Hubs Cloud is a product offering that allows our customers to spin up their own Hubs stack via the AWS Marketplace. Hubs Cloud stacks are independent instances of Hubs, fully controlled by each customer. However, our unique use of the Marketplace, in combination with AWS Cloudformation and Habitat, allows us to update the software on these independent stacks as we continue to improve Hubs. Hubs Cloud represents a new way of offering cloud solutions, as an alternative to conventional SaaS, that gives users control of their data and systems while providing a path for continuous software delivery.  In addition to offering Hubs Cloud as a product, we will be using it internally to run our own experiments as we explore new use cases for Hubs.

Our stack is open source! You can browse through it here:
