Teams & Roles

Building & Designing

We are designers, engineers, creators and problem solvers. We work in the fishbowl known as open source, with a clear focus on making the Web better. Working with us, you’ll help build amazing things like Firefox, Rust and more. To be part of the team, we ask that you be awesome, intelligent and proud to be moving the mission forward. Rock on.

We also work hard to keep your identity secure, the lights on and the refrigerators filled. Yep, we do it all.

What do you want to change about the world of work?

Business at Mozilla is far from usual. Even for those who wear ties to work, things are a little more unconventional and creative. As the core growth and legal team, our efforts are focused on bringing in new business initiatives and partnerships that will support our current partners, team members, communities and, best of all, mankind. What do you say? Are you ready to get down to business?

At Mozilla, we have powerful stories to tell — and talented storytellers who share them with the world at large. Working with this team of product marketing, public relations and brand-building dynamos, you’ll have an opportunity to tell thousands of stories from all around the globe, to inspire thousands more and to build our legacy as an innovative, world-changing non-profit. Hope you have your pencils sharpened.

From the passionate people you’ll learn from to the chances you’ll have to make the Web a better place, your time with Mozilla will be unlike any other.

Life at Mozilla

What makes us… us.

At Mozilla, we like to find the best and most fun ways to do things, and we like to think it shows in all that we do. Throw in a good dose of freedom, teamwork and perks, and you’ve got life at Mozilla. And we haven’t even mentioned the snacks yet.

How we take care of our people

We offer a unique, flexible work environment where individual contribution and impact produce results greater than a paycheck and benefits. But pay and benefits are important, so we offer market-competitive salaries and cash-based incentives as well as a full stack of benefits.
