One of our software clients has created a fast, privacy-oriented web browser that is combined with a blockchain-based digital advertising platform.  This technology is reinventing the Web for users, publishers and advertisers. Users get a private, speedier 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.

We are looking for an engineer who can help us stay one step ahead of fraud within our ecosystem.  This position is vital to helping us make sure that rewards go to users, not to bad actors.  We are looking to refine, automate, and expand the ecosystem’s anti-fraud processes, and build to a more self sustaining longterm model  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.
