Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people.

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.

About this team and role:

As a Staff UX Product Designer with an AI focus, you’ll help define the future of browsing and shape the next generation of AI-powered features in Firefox. You’ll collaborate with product managers, engineers, researchers, and content designers to create elegant, scalable experiences rooted in Firefox’s values of privacy, simplicity, and performance. In this high-impact, cross-functional role, you’ll explore new ideas, bring design systems to life, and elevate product quality with refined, visually engaging, and thoughtful design. You’ll influence how millions of people interact with the web—balancing trusted UI patterns with bold, forward-thinking AI innovations.

You’ll design at the forefront of AI technology, shaping how people and businesses benefit from powerful new tools while influencing the future of Firefox—the only major browser not backed by billionaires. Join our distributed, mission-driven team and help make the web better for everyone as we build meaningful new AI experiences.

What You’ll Do:

Design AI-powered features for Firefox on desktop, guiding ideas from early sketches to live experiences.
Combine familiar interface patterns with inventive AI features so browsing feels fresh, fast, and easy to use.
Work autonomously to identify problems and propose solutions that align with product strategy, user insights, and technical constraints.
Use storyboards, wireframes, and prototypes to explore and refine new ways for people to interact with AI in the browser.
Work side-by-side with product managers, engineers, researchers, and content designers to make design decisions that work for people and for the product.
Design with privacy, accessibility, and trust at the core of every interaction.
Help grow and adapt Firefox’s design systems to keep the desktop experience consistent and cohesive.

What You’ll Bring:

7+ years of product design experience, ideally working with complex workflows or multi-step processes.
Experience designing AI experiences for consumer products with large user bases.
Background in ethical AI practices and privacy‑first design.
Familiarity with AI-powered tools or excitement to help shape how people use AI in everyday work.

A strong, user‑centric portfolio with polished UI craft and innovative interaction paradigms.
Proven track record of delivering end‑to‑end design in ambiguous, large‑scale projects.

Strong grasp of visual and interaction design principles: layout, typography, motion, accessibility, and brand expression.
Proficiency with Figma and other modern prototyping tools.
Ability to communicate clearly with cross‑functional partners and influence without authority.
Collaborative, flexible, low‑ego approach; thrives in fast‑paced, distributed teams.
Talent for turning complicated workflows into clear, intuitive experiences.

What you’ll get:

Rich medical, dental, and vision coverage
Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)
