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.

• Build and maintain strong relationships with key media, analysts, and privacy and advertising stakeholders.
• Identify and manage high-impact moments to insert Mozilla into relevant industry and cultural conversations.
• Partner closely with external vendors, agencies, and internal stakeholders to execute programs efficiently and at a high standard.
• Operate autonomously with a self-starter mindset—consistently generating fresh, creative ideas and uncovering new opportunities to drive visibility, even in the absence of major news or direction.

What you'll bring:

• 10+ years of relevant experience in communications, including experience in or an understanding of marketing and advertising.
• 3+ years working for a product-driven organization in tech. (Advertising or ad tech industry experience is a bonus).
