Acquisition Marketing Manager

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.

Mozilla is seeking an Acquisition Marketing Manager with a passion for growth marketing and digital media optimization to join our team focused on Firefox browser adoption!

• Generate weekly and monthly reporting decks that synthesize findings and highlight performance trends and optimization opportunities.
• Collaborate cross-functionally with data science, product marketing and other collaborators to ensure alignment between acquisition efforts and broader product goals.
• Use your knowledge of digital marketing trends and competitive benchmarks to help Mozilla succeed with its mission-driven, privacy-preserving marketing approach.

• 3+ years of experience in digital marketing, with a focus on paid media and/or performance marketing.
• Experience managing media campaigns in partnership with agencies or as part of an in-house team.
