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, and Pocket, a service for keeping up with the best content online. 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:

At Mozilla, one of our four commitments is to build “...an internet that includes all the people of the earth - where a person’s demographic characteristics do not determine their online access, opportunities, or quality of experience.” Being inclusive and transparent for the betterment of humankind is at the core of our values. When you work at Mozilla, you give yourself a chance to make a difference in the lives of Web users everywhere. We take care of you by providing industry leading benefits.

Our Services Engineering team strategy is to fuel product growth and diversification by investing in flexible, easy-to-use, and reliable services. Our approach is privacy first as we help people get to the right information in the right context at the right time with less effort. We'd like you to join us in building services to help surface the content our customers want.

Our team is geographically-distributed, working in the open is the norm, and we value a culture of learning. We know that different experiences make engineering teams stronger.
