Selena will lead the product and technology teams at the Wikimedia Foundation. These teams support the technology infrastructure and innovation that powers Wikimedia projects, including Wikipedia, one of the most visited websites in the world with more than 16 billion pageviews per month. They also enable more than 300,000 global volunteers to edit Wikimedia projects each month.
“Selena has a proven track record of delivering results by enabling individuals and teams to tackle unique and often complex challenges,” said Maryana Iskander, CEO of the Wikimedia Foundation. “She has dedicated her career to open source technologies for empowerment and inclusion.”
At Mozilla, where she has been for nearly a decade, Selena currently leads the Firefox organization of more than 400 people responsible for all Firefox product and technology functions including desktop, mobile, web platform, and browser services. She oversaw some of the company’s most significant achievements including performance projects like Quantum Flow, architectural changes like Project Fission, key features like Enhanced Tracking Protection and Total Cookie Protection, and services such as Firefox Monitor. In her nine years at Mozilla, Selena held various other roles including Vice President for Firefox Desktop, Senior Director for Web Platform Engineering and Gecko Runtime, and Senior Manager for Gecko Security Engineering.
Selena also brings experience from her previous roles as co-founder of Prime Radiant, a software as a service business that explored how to improve business processes at scale with checklist automation software, and as Consulting Director of Development for The Ada Initiative, an organization that was dedicated to increasing the participation of women in open source and technology communities. She was a major contributor to PostgreSQL, one of the largest free and open source databases in the world.
“Open collaboration produces better solutions for the world, and technology is a critical enabler of making this true,” said Selena. “I look forward to contributing to Wikimedia’s inspiring free knowledge mission.”
As Chief Product and Technology Officer, Selena will work with Wikimedia Foundation staff, technical contributors, volunteer developers, researchers, and communities to support Wikimedia’s 2030 Movement Strategy to advance free and open access to knowledge. The majority of the Foundation is focused on product and technology development in service of our mission.
