UK: London (Preferred) - Hybrid
About BraveBrave is on a mission to protect the human right to privacy online. We’ve built a free web browser that blocks creepy ads and trackers by default, a private search engine with a truly independent index, private AI assistant, latest privacy and security features, and a private ad network (opt-in!) that directly rewards you for your attention. Already over 120 million people regularly use Brave for a faster, more private web. Millions more switch every month.
The internet is a sea of ads, hackers, and echo chambers. Big Tech makes huge profits off our data, and tells us what’s true and what’s not. Brave is fighting back. Join us!

What We Do
Brave Software’s fast, privacy-oriented browser, combined with its blockchain-based digital advertising platform, is reinventing the Web for users, publishers and advertisers. Users get a private, speedier Web experience with much longer battery life, publishers increase their revenue share, and advertisers achieve better conversion. Users can opt into privacy-respecting ads that reward them with a frequent flyer-like token they can redeem or use to tip or contribute to publishers and other content creators. The Brave solution is a win-win for everyone who has a stake in the open Web and who is weary of giving up privacy and revenue to the ad-tech intermediaries. Brave currently has over 30 million monthly active users and 9.6 daily active users. Brave Software was co-founded by Brendan Eich, creator of JavaScript and co-founder of Mozilla (Firefox), and Brian Bondy, formerly of Khan Academy and Mozilla.
