Engineers needed to fight online fraud with machine learning. Join us!<p>Sift Science (http://siftscience.com) is a Y Combinator (S11) startup, ready for great engineers to join our cause in sunny/foggy San Francisco.<p>Last year there was $4B in online fraud and 70% of that was driven by organized crime. The opponents are no longer script kiddies -- they’re just as smart and capable as any of us, and their attacks are evolving in both scale and sophistication. As the world becomes more connected, this problem will only get worse. We’re building a large-scale machine learning system paired with elegant visualization/UI tools to help ecommerce businesses take a stand. We’re literally fighting bad guys, and have big plans beyond fraud.<p>Our team includes several ex-Googlers with experience spanning e-commerce analytics, search quality, ads quality, and speech recognition. We value respect, collaboration and creativity, and don't take ourselves too seriously. We want to create a great place to work -- a company is nothing without its people.<p>As an early engineer, you’ll have a huge impact on the product, direction and culture of the company.<p>You must:<p>* Get stuff done<p>* Respect and treat others well<p>* Be comfortable wearing different hats<p>* Thrive on responsibility and freedom<p>* Bulldoze through unfamiliar problems<p>A background in machine learning, HBase, Hadoop, Java, Rails, MongoDB, d3, jQuery, HTML/CSS, data visualization and/or AWS is great, but not required. Just be ready to learn quickly.<p>We can promise two of these five things:<p>* Daily inspirational quotes read in-person by William Shatner<p>* Interesting and meaningful technical problems<p>* All-you-can-eat caviar breakfast, lunch, and dinner<p>* Weekend Lamborghini rentals<p>* An incredible team that will challenge and respect you<p>Our investors include Union Square Ventures, First Round Capital, Max Levchin (PayPal co-founder), Marc Benioff (Salesforce CEO), Chris Dixon (Andreesen Horowitz), SV Angel, and others well-versed in e-commerce, payments, and enterprise software. We offer market salary, meaningful equity, health insurance, custom dev setup, beer o’clock, relocation help, etc. just like everyone else. But what’s most important is the work you do and who you do it with. Everything else is just icing on the cake.<p>Let’s make the world a better place.
