Description
ABOUT NABU CASA
Nabu Casa, Inc was founded in 2018 by the founders of both Home Assistant https://home-assistant.io/, the open source home automation platform, and Home Assistant OS https://github.com/home-assistant/operating-system, the operating system that turns your device into a smart home hub powered by Home Assistant. These projects have seen an immense growth and have helped shape DIY home automation communities around the world.
After being involved in the Internet of Things industry for many years, we realized that there is a need for a cloud service that aims to put users, their privacy and their data first. Such a cloud can only be built as an extension to a platform that does the same: Home Assistant.
With Nabu Casa we are building this cloud service and we’re calling it Home Assistant Cloud.
We are a profitable company with no external investors. Our funding comes directly from users who subscribe to Home Assistant Cloud and purchase Home Assistant hardware, ensuring our only stakeholders are our employees and our users. We also support other open-source projects, including those focused on hardware, standards, and voice technology.
THE ROLE
Nabu Casa is looking for a full-time Elixir Backend Engineer to join our Cloud & Infrastructure team and work primarily on Home Assistant Cloud services.
As one of the most active open-source projects in the world, Home Assistant exists because of its community. To empower this community and allow more users to enjoy the harder-to-reach features of Home Assistant, we have created our subscription service, Home Assistant Cloud. This service gives the community access to features usually reserved for power users with expensive hardware at home. Current features such as remote access and text-to-speech / speech-to-text support are made available without ever compromising on privacy.
We're looking for someone who will maintain the existing features and infrastructure and help us create valuable new features with efficiency and privacy in mind.
