Job Description

Are you passionate about creating exceptional user experiences and shaping the future of smart homes?

Nabu Casa is seeking a Senior User Experience Designer to join our Product & Design team full-time, focusing on Home Assistant. You’ll transform our vision into tangible prototypes and design intuitive, user-friendly experiences for our users’ smart homes.

Home Assistant, one of the most active open-source projects globally, powers over a million households, providing convenience, comfort, security, personalization, and more by automating and controlling devices. We are committed to our Open Home vision — a smart home built on privacy, choice, and sustainability.

The Nabu Casa Product & Design team envisions the future of the Home Assistant project and guides us there. We oversee product roadmaps and manage the alignment, discovery, ideation, design, and validation phases of each product, collaborating with our engineering team for implementation and our marketing team for launch. Since our formation last year, we’ve been dedicated to steering Home Assistant towards a powerful yet user-friendly experience.

In contrast to typical corporate or startup roles, we actively maintain our project and its open-source community. We communicate transparently with contributors and users, keeping them informed and aligned with our direction. You’ll have easy access to users for feedback and validation via our forums. You’ll collaborate with Nabu Casa engineers and community contributors to bring your designs to life.

  • Open Source Collaboration: Work with community contributors on our products. Improve their contributions through better design.
  • Stay Updated: Keep abreast of the latest UX design methodologies, industry trends, and best practices to enhance our design processes and deliverables.


  • Mastery of Figma: Proficient in essential and advanced Figma features, including autolayout, design libraries, dev mode, prototyping tools, components, text and color styles, variables, and plugins.
  • Design Thinking Skills: Ability to solve problems using the best design methodologies and tools throughout the product development lifecycle.
  • Self-Driven: Proactively improve products and design processes. Become the design owner of specific product areas.
  • User-Driven: Empathetic towards users, understanding the importance of frequent user interactions. Document and iterate on user research findings using the right UX tools.
  • Craftsmanship: Keen eye for design details and aesthetics, ensuring precise alignment and consistency. Understanding of typography, color theory, grid systems, and composition.
  • Smart Home Knowledge: Familiarity with home automation and alignment with our Open Home values of privacy, choice, and sustainability. Experience with Home Assistant or other home automation software is a plus.
  • Accessibility Standards Knowledge: Deliver user experiences that are accessible to all users, including those with disabilities.
  • Basic Software Development Understanding: Knowledge of what frontend and backend developers need to implement designs, and a general understanding of how computers work.
  • Fluency in English.

Additional Preferred Skills:

  • Affinity with Open-Source Development: Experience contributing to open-source projects and engaging with their communities.
  • Software Experience: Proficiency with creative web development, collaboration, and design software.
  • Coding Skills: Basic knowledge of HTML, CSS, simple JavaScript, and YAML files.
