Mozilla jobs, judged for you, free

What they do

Mozilla Corporation makes Firefox, a web browser that is focused on privacy. The non-profit Mozilla Foundation owns the company, so it has no shareholders. Mozilla builds open-source software with volunteers all over the world. The Mozilla family also includes MZLA, which makes the Thunderbird email app. Mozilla hires for these organizations on one board.

What they value

• Welcoming differences, because diverse views give better solutions.
• Being relationship-minded, with empathy and active listening.
• Responsible participation through transparent and open processes.
• Grit, which means facing obstacles with optimism and learning from results.

Where they hire

All roles are remote. Most are in Canada, the US, and Germany. Some are in the UK, France, Sweden, Spain, Belgium, Finland, and the Netherlands. Five Firefox engineering roles are contracts. Thunderbird roles need people who live in the listed country and have permanent work authorization. Thunderbird does not sponsor visas. Enterprise sales roles in Germany and France need travel.
