Python Engineer, Graph & Data Ingestion

New York, United States Full-time

Applecart deploys proprietary technology to run smarter advertising campaigns. We work with some of the nation’s most prominent corporations, non-profit organizations and political candidates to activate and communicate with key target audiences at a scale and level of efficacy previously thought impossible. Part high-level strategic consultancy, part cutting edge data R+D lab, Applecart offers proven solutions derived from objective, iterative experimentation. Our core offering is a proprietary social graph that leverages publicly-available data to map real-world relationships between individuals at national scale. Our roots are in politics, where we have tested and honed our methods at every level, in high-impact circumstances. We’re branching out beyond political campaigns to tackle new advertising challenges in which determining “who knows whom” provides decisive advantages for our clients.

Applecart’s political work has been featured by The Colbert Report, CNN, The Washington Post, The Associated Press, USA Today, The Huffington Post, among other prominent news outlets.

As a Python Engineer on our engineering team, you will be responsible for sourcing, enhancing and integrating data sources to our social graph while providing optimizations to said graph for creation of powerful machine learning applications. Your work will directly affect our clients in the form of election outcomes, increasing political and non-profit fundraising yields and optimizing advertising spends and risk assessments.
