Elixir Backend Engineer

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.

• Build and maintain backend services primarily using Elixir.
  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.
• Help operate and support production services, including troubleshooting issues, improving reliability, and participating in the operational ownership of cloud systems.
• Work on authentication, subscription, and payment-related services that power Home Assistant Cloud.
• Stay up-to-date with industry trends and share best practices with the team.

What you need to have

• Professional experience developing production applications in Elixir.
• Experience with TypeScript.
• Basic knowledge of system administration.
• Experience with Git and GitHub.
• Be based in North America, Latin America, or Europe, and be able to regularly overlap with the team during the afternoon in Central European Time (CET). The team tries to schedule most meetings between 2:00 PM and 5:00 PM CET to maximize collaboration across time zones.
• Fluent in English, both written and spoken.
• Experience building or maintaining authentication and/or identity management systems.
• Experience working with payment, billing, or subscription platforms.
