Frontend Engineer (Home Assistant)

We are looking for

The Open Home Foundation is looking for a Frontend Engineer based in Europe to join our Home Assistant team.

Home Assistant is not a website or a content platform. It is a complex, real-time web application used by millions of people to control and automate their smart homes. The frontend is a full-featured progressive web application (PWA) that manages real-time state for hundreds of data and control points simultaneously, renders dynamic dashboards and data visualizations, communicates bidirectionally with a backend over WebSockets, and runs across desktop and mobile as an installable application.

We are looking for an engineer who thrives on building sophisticated, stateful applications, not someone whose experience is primarily in building websites, landing pages, or CMS-based projects.

Frontend Technical Stack

The Home Assistant frontend is a modern, performance-focused progressive web application (PWA). Our core stack relies on:

• TypeScript: All development is done in TypeScript, ensuring code quality and maintainability across a large, complex codebase.
• Lit and Web Components: We build with the Lit library and native Web Components. We have a large component library, and understanding the underlying platform (custom elements, shadow DOM, DOM APIs) is essential.
• Real-time state management: The application manages hundreds of data and control points with live state updates over WebSockets. Efficient rendering and state synchronization are core challenges.
• Modern Web Standards: We prioritize native browser capabilities over heavy frameworks. Understanding the web platform itself matters more than familiarity with any particular framework.
  
  

What You Are Going To Do

• Conduct code reviews of pull requests from your teammates and our community, identify and resolve technical issues, ensuring we maintain high coding standards.
• Collaborate closely with engineering, design, and product teams to develop our progressive web application for new features based on community feedback, product specifications, and requirements.
• Continuously improve our frontend codebase by elevating its quality, maintainability, and scalability, and actively participate in shaping frontend architecture and technical decisions to ensure long-term innovation and performance.
• Actively engage with our community by investigating and addressing user-reported issues, and prepare tasks that can be clearly defined and easily picked up by community contributors.
  
  

What You Need To Have

• 3+ years of professional TypeScript development experience.
• Experience developing and optimizing progressive web applications (PWAs).
• Hands-on experience with modern frontend frameworks and libraries (e.g., Lit, React, Angular, Vue).
• Strong grasp of Web Components principles.
• Ability to work independently, with strong problem-solving skills and attention to detail.

• Professional fluency in English, excellent written and verbal communication skills in English.
• European residency, you must be currently based in Europe and eligible to work within it.
  
  

It would be great if you also have

• Prior contributions to Home Assistant (especially HA cards or custom UI components) or other open-source projects.
• Passion for and experience with (ie: already a user of) Home Assistant, or a strong interest in smart home technology and automation.
• A drive to craft delightful user experiences, with attention to detail such as micro-interactions.
• Affinity for the open-source philosophy and community-driven development.
• Experience working with Lit or web components
• Knowledge of web accessibility standards and best practices.
• Familiarity with frontend testing framework (e.g, Vitest, Jest, Cypress).
• A knack for data visualization, understanding relevant principles, and best practices.
