Anti-Fraud Engineer

About Brave

Brave 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, a browser-native crypto wallet, and a private ad network (opt-in!) that directly rewards you for your attention. And we’re just getting started. Already 50 million people have switched to 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!

Summary

Brave is looking for an engineer who can help us stay one step ahead of fraud in our Brave Ads ecosystem. This position is vital to help us make sure that rewards go to Brave users, not to bad actors. We are looking to refine, automate, and expand the BAT ecosystem’s anti-fraud processes, and build more of the necessary tooling over time. We are looking for somebody who always prefers a simple solution over a complex one and who can take whole solutions from end to end.
