About Nabu Casa
Nabu Casa, Inc was founded in 2018 by the founders of both Home Assistant, the open source home automation platform, and Home Assistant OS, the operating system that turns your device into a smart home hub powered by Home Assistant. These projects have seen 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 realised 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 backend developer 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.
What You Are Going To Do
- Contribute to the design and implementation of scalable, high-performance, and reliable backend applications
- Participate in code reviews as part of our collaborative development process
- Collaborate cross-functionally to define, design, and ship new features
- Contribute to maintaining and improving the performance, quality, and responsiveness of the cloud services
- Implement security and data protection best practices in your work
- Stay up‑to‑date with industry trends and share best practices with the team
What You Need To Have
- At least five years of professional experience in back‑end development
- At least two years of professional experience in Node.js/Typescript
- Basic knowledge of system administration
- Experience with cloud services (preferably AWS)
- Experience with Git & Github
- Fluent in English, both written and spoken
It would be great if you also have
- Experience in NestJS, Elixir, Terraform, Grafana or Python
- Personal experience using Home Assistant
- Knowledge in modern frontend app development
- Affinity with open‑source development and philosophy
