Sift Science (<a href="http://siftscience.com" >) - San Francisco, CA
Sift Science uses large-scale, real time machine learning to fight online fraud. It's a problem that cost U.S. merchants  $10B last year, and 70% of it is organized crime. Attacks have rapidly evolved in breadth and depth, but current rule-based systems don't scale.
We're looking for engineers of all flavors -- distributed systems, web development, data visualization, and of course, machine learning. We're a tight-knit team that likes board games, yummy food, and solving challenging technical problems. Check out <a href="https://siftscience.com/jobs" >
We're also looking for account managers, solution engineers, sales, and a product marketing leader.
