Sr. Anti-Fraud Engineer

(Remote, Full Time)


Job Description

About the Company: Brave Software International SEZC (Website)
Location: Remote
Salary: Based on experience

Brave is on a mission to protect the human right to privacy online. They’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 they’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 them!

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


  • Experience with Python, JavaScript, Ruby, C++, Go, Java or other similar language.
  • Experience with SQL, Postgres/Redshift, and building analytics queries.
  • Experience building robust API endpoints.
  • Experience stopping bad actors in a system, e.g. ad fraud, e-commerce fraud.
  • A working understanding of fraud vectors, both small scale (client-side hacks) and large scale (botnets).
  • Experience with software development via distributed development teams.
  • Comfort working in an open-source setting.
  • A passion for helping protect users’ privacy and security.
  • Proven record of getting things done.
Nice to haves
  • Have built/trained statistical / machine learning models at scale to solve real world problems.
  • Experience with ad-tech/martech ecosystem.
  • Familiarity with the world of cryptocurrency, especially Ethereum.
  • Familiarity with challenges in privacy preserving ecosystems.
Working at Brave
  • Industry-leader in privacy, with a research and engineering team that’s innovating every day to keep people safer online and beat Big Tech.
  • Highly competitive salaries & benefits, and generous home-office stipends.
  • Fully remote team (no office, no commute).
  • Welcoming, humble, ridiculously smart teammates, and a truly flat org structure.
  • Opportunity to get in early at a hyper-growth company and revolutionize the web.
  • Oh, and did we mention Brendan, their CEO & co-founder, invented JavaScript?
