Frontend Engineer

Role Description

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

• 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. 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.
• Modern Web Standards: We prioritize native browser capabilities over heavy frameworks.

What you are going to do

• Conduct code reviews of pull requests from your teammates and our community, identifying and resolving technical issues.
• Collaborate closely with engineering, design, and product teams to develop our progressive web application for new features.
• Continuously improve our frontend codebase by elevating its quality, maintainability, and scalability.
• Actively engage with our community by investigating and addressing user-reported issues.

Qualifications

• 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.
• Extensive proficiency with Git and GitHub workflows.
• Professional fluency in English, excellent written and verbal communication skills in English.
• European residency, currently based in Europe and eligible to work within it.

It would be great if you also have

• Prior contributions to Home Assistant or other open-source projects.
• Passion for and experience with Home Assistant or a strong interest in smart home technology and automation.
• A drive to craft delightful user experiences, with attention to detail.
• 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 frameworks (e.g., Vitest, Jest, Cypress).
• A knack for data visualization, understanding relevant principles and best practices.

Benefits

• Five weeks (twenty-five days) of paid time off.
• Fourteen days of paid sick leave if your country/laws treat them as unpaid.
• Six weeks of paid and six weeks of unpaid parental leave to be used in the first year after birth.
• A budget for your work hardware once you start.
• A 50% contribution to your internet connection fee at your home workspace.
• Ability to spend work time maintaining Home Assistant-related side projects.
• Total compensation package that matches the 75th percentile for the new hire's role, seniority, and local market rates.
